26 Documenta Praehistorica XLVIII (2021) Introduction Caches of various types of artefacts are one of the most interesting and intriguing archaeological finds. In many cases they are unpredictable, unexpected and, very often, accidental, especially, when we are dealing with the Stone Age period. While extreme- ly spectacular, examples of lithic caches consisting of highly elaborated bifacial points are known for the Solutrean culture (Volgu) in Europe (Thévenot et al. 2019), and for the Clovis (Anzick, Fenn, Richey- Roberts etc.) in North America (Frison, Bradley 1999; Huckell, Kilby 2014). There are also many manifestations of caching strategy in other parts of the World (Eastern Europe, Near East, Mesoamerica, Siberia, Central Asia and Far East). Chronologically lithic caches are mostly connected with the Middle- Late Palaeolithic and the Neolithic periods; they illustrate special technological decisions both for mobile and sedentary users, and, in terms of econo- Knap & keep> Late Palaeolithic-Neolithic caches, Far East ABSTRACT – The tradition of lithic caches illustrates a special strategy of storing lithics which were extracted from chaîne opératoire for some time to be kept/hidden in a special place with/without subsequent return and use. For the Palaeolithic – Neolithic/Jōmon of the Far East (Russian part and the Japanese Archipelago) within the frame of 35 000–2400 cal BP, this tradition demonstrates an impressive multiplicity (more than 400 cases), high diversity, duration, dynamics, and local varia- bility. Such an abundant source of data opens rich perspectives for detailed technological analysis, functional interpretations, and interregional correlations, with analogies in the Stone Age cultures of the Near East, Europe, and North America.

This list includes only finds that are not related to the burial context, and are not the part of burial offerings. On the one hand, such rich material requires detail- ed technological use-wear analysis, classification and contextual subdivision, regional and inter-regional correlation. On the other, and the authors put a spe- cial emphasis on this, it creates unique prerequisites for the interpretation of behavioural attitudes (the ‘knap & keep’ strategy) within the economic and ri- tual activities of hunter-gatherers-fishers. The follow- ing overview of the caches in the Russian Far East will be done in more detail, while for the caches on Japanese Islands we will try to demonstrate the sta- tistical data, contextual tendencies and local tech- nological variabilities. mical context, lithic caches are typical both for the hunter-gatherer and agricultural societies. So far, the data about lithic caches dated by the Pa- laeolithic – Neolithic/Jōmon times on the territories of the Russian Far East and the Japanese Archipe- lago is presented only in a preliminary form in a se- ries of articles. Most of these, with a very few excep- tions (e.g., Dyakov 1997; Kanomata, Tabarev 2020), are in the Russian and Japanese languages and not known by a wide archaeological audience. It is noteworthy, however, that the first information about the accidental find of a lithic cache (Naruka- sanka) comes from as early as the second half of 19th century. According to the publication of Nobu- taro Ono (Ono 1897)1, somewhere between 1865– 1867 and while digging an irrigation channel near the villages Naruka and Sanka (Fukui prefecture), local farmer Kanji Nozawa discovered a huge stone axe (54cm) arranged upon two chipped pebbles and about 30 arrow-points (Fig. 1.1–2)2. The evidence of possible lithic caches in the Russian Far East appeared in the archaeological literature only in the 1950s and 60s due to the later start of wide-scale field inves- tigations in the region as a whole. One of the first hints of caches is connected with the finding of a large leaf-shaped biface artistically made from the local grey chert on Sakha- lin Island3 – its length (32.5cm), thickness (0.7cm), and sophisticated technology of pressure flaking puts this find on a par with the best Solu- trean and Clovis (Paleoindian) bifa- cial points. Note also the general mor- phological similarity of the point from Sakhalin with the points from Narukasanka cache (Fig. 1.3). Since these early discoveries the in- formation on lithic caches in the Rus- sian Far East (Amur Region, Mariti- Fig. 1. 1,2 First publication and reconstruction of the Narukasan- ka cache, Japan; 3 bifacial point, Sakhalin Island. 1 The detailed story about the Narukasanka cache, along with photos and drawings, was published in a special paper in late 20th century (Matsui 1980). 2 If the dates (1865–67) are correct the cache in Japan was found even earlier than the famous Volgu cache in France (1874). 3 The artefact has no documentation, but with high probability was located within a destroyed archaeological site near Nogliki vil- lage (Sakhalin Island) in the mid-1950s and could be dated to the Early Neolithic (11 000–9000 BP). Currently the biface is on show in the Archaeological Museum, Institute of Archaeology and Ethnography, Novosibirsk, Russia (Tabarev 2012). 4 The language aspect of the problem is also important: the Russian word ‘klad’ means “something very precious for the owner and hidden, buried in the ground”. The term ’cache’ in the translations of Russian archaeological articles into English is in recent use, and before this the authors preferred another word – ’hoard’ – for special finds of bronze or gold items. In the Japanese lan- guage the English word ’cache’ is equivalent to ’Intoku Ikou’ and ’Heitan ikou’ (caching feature). Andrey V. Tabarev, Darya A. Ivanova, and Yoshitaka Kanomata 28 Evidence of a caching strategy on the territory of the Russian Far East It would be logical to preface an overview of lithic caches on the territories of the Russian Far East with some information about similar complexes known in Siberia and Mongolia. They confirm the very early and wide geographical spread of this tradition. Several finds were mentioned in the archaeological literature devoted to the Palaeolithic of Kemerovo District (Western Siberia) in 1960 – e.g., a complex of 19 preforms and tools near Ail village, and a pos- sible cache of eight tools near Shestakovo village (Okladnikov 1968). Another remarkable discovery was made during the excavations of Tumulur site (Aldan River, Yakutia)5 in Strata IV within the Upper Palaeolithic context belonging to Dyuktai culture. Eight lenticular bifaces (from 7 to 13cm long) were located in a compact cluster (20x25cm), and due to the absence of any dwelling or hearth features the researchers interpret- ed them as a possible cache (West 1996.197–198). The first Palaeolithic cache with- in a clear stratigraphic context was found in Northern Mongolia (the Tolbor river valley) in 2010 – it consists of 57 standard flakes carefully piled in a shallow pit (30x30cm), and could be con- nected to the local hunting activi- ties within the frame of 27 000– 17 000 cal BP (Gladyshev et al. 2011; Tabarev et al. 2013). Re- cently, one more cache (11 core preforms from local jasper) was found in Southern Mongolia (Go- bi) by a joint Polish-Mongolian expedition and preliminary da- ted by the Middle Palaeolithic (Masojc 2019). Directly on the territory of the Russian Far East, several sites with lithic caches of various type, content, and location have been recorded there (Fig. 2). The most obviously interesting of these is Novopetrovka-II, one in a series of sites excavated in the Middle Amur stream near Blagoveshchensk during the 1960s. These sites belong to the Novopetrovka Neo- lithic culture (Novopetrovka ‘blade culture’) which is dated by charcoal and charred remains on pottery to between 12 600 and 10 800 cal BP (Derevianko et al. 2020). The first cache was found on the floor of dwelling #2 in a small pit (40cm in diameter), and consists of seven blade cores with the negatives of recent removals and one blank for the core (Fig. 3.1; Derevianko 1970.42–44). Two more similar pits with lithic caches (about 10cm deep and 35cm in diameter) were described in dwelling #4 – both in- cluded three blade cores each in the initial stage of the exploration (Derevianko 1970.66–67). The next evidence of caching is connected to the Lower Amur region (near Khabarovsk), where since the 1920s archaeologists have studied the sites of the Osipovka culture. It was successively identified as Palaeolithic, then Mesolithic, and – after the dis- covery of early pottery – as the Initial Neolithic, and dated between 14 200–9900 cal BP. Despite the long history of exploration and representative archaeolo- gical collections a data connected to the lithic cache only appeared in 2015 in the course of the excava- 5 Tumulur site was discovered in 1964 and studied during 1964–1982. It is dated between 16 600–13 600 cal BP. Fig. 2. Russian Far East. Sites with the caches listed in the text. 1 No- vopetrovka-II; 2 Osinovaya Rechka 10; 3 Ustinovka IV; 4 Ustinovka III; 5 Ushki I. Knap & keep> Late Palaeolithic-Neolithic caches, Far East 29 tions at Osinovaya Rechka 10 site6. Three bifacial artefacts (axes) were found stacked in a pile in the very southeast part of the unit in layer 4 (Hashidu- me et al. 2019.27, 36–37, Pl. 2). The context does not point to any special pit or dwelling floor (Fig. 4.1–3). Two examples of lithic caches are known in the Ma- ritime Region. Both were recorded at the sites of the Ustinovka group (complex) in the Zerkalnaya River Valley. The sites are dated between 18 000–10 000 cal BP, and demonstrate the transition from the Final Palaeolithic to Early Neolithic periods. In 1997 Vladimir I. Dyakov (Fareastern Federal University, Vladivostok) published a short paper in English about the excavations at the Ustinovka IV site with a brief description of the compact complex (30x 30cm) of eight bifaces grouped around the biggest one which, possibly, was set vertically. According to the author, this complex was located between the depressions of dwellings #1 and 3, although no pho- tos or drawings have been presented which con- firm this observation (Dyakov 1997.20). In a later version, Dyakov clarified that the central biface (10.3cm) was erected on a small ’pedestal’ with a height of 6cm. He again gave no photos or figures with the original position of the complex, but only the plan of the unit and schematic drawings of only seven (of eight) bifaces (Dyakov 2000.41–42, 193). Unfortunately, there are no carbon dates for the sites and its age (14 000–12 000 cal BP) is determined solely based on analogies with neighbouring com- plexes in Zerkalnaya River Valley. Another location about 1.5km from Ustinovka IV site, namely Ustinovka III, was discovered during the early 1960s and excavated over several research cycles. The last one was conducted by a joint Rus- sian-Japanese expedition and took place from 1992– 1997. It was crowned with the discovery of the ear- liest Neolithic pottery for the Maritime Region7. Moreover, according to the related publications dur- ing the 1995 field season in the northwestern part of the unit specialists located in situ a concentration (44x36cm) of lithics, including 171 flat flakes (11x8– 7x7cm) in a very dense context, which was inter- preted as a “cache of flakes hidden in container, possibly a kind of leather bag“ (Derevianko, Kono- nenko 2003.68–69; Kononenko 2001.47). Unfortu- nately, even in this case only a description, statisti- cal data and an approximate drawing are available to readers (Fig. 3.2). A large cluster of multilevel settlements near Ushki Lake on Kamchatka Peninsula has been under per- manent archaeological research since 1961. All lev- els (VII-I) vividly illustrate the development, evo- lution, and peculiarities of the Final Paleolithic-Neo- lithic cultures (various types of dwelling construc- tions, burials with rich offerings, adornments, work- ing areas, storage pits, etc.). In 1983 during the ex- cavation of the entrance of sub-terranean dwelling #9 (i.e. cultural complex of Level VI, 12 200–11 600 cal BP; Ponkratova, Chachula, and Clausen 2021) at the Ushki I site, archaeologists met with a com- pact set of 12 bifacial preforms for microblade cores. They were made from local grey chert and techno- logically are very similar to the microblade cores explored in frames of the Yubetsu technique which is typical for the Final Palaeolithic of the Japanese Islands. These cores were described in several arti- cles about Ushki I Site, but the exact context of the feature became known only recently after the pub- 6 Osinovaya Rechka 10 was a part of multi-year joint Russian-Japanese archaeological project. There are two carbon dates for the site: 11 150–10 930 cal BP and 13 094–12 952 cal BP. 7 The authors published two dates for Ustinovka III site – 10 500 (OSL) and 9305±31 BP (14C) (Kononenko 2001.46–47).

Ivanova, and Yoshitaka Kanomata 30 lication of the photos and drawings from the original field report (Fig. 5.1–3; Fedor- chenko, Belousova 2020.314). Thus, despite the small number and incom- plete documentary support for all the finds (exact provenience, detailed photos, and drawings, etc.), the strategy of lithic caches on the territory of the Russian Far East de- monstrates a long technological tradition and contextual/functional variability. There are caches of preforms (cores, flakes) and finished tools (bifaces, axes), caches in as- sociation with dwelling constructions and without it, technical (prosaic) caches kept for further use, and caches of ritual arran- gements. Lithic caches in the Palaeolithic-Jō- mon, Japanese Islands In comparison with the continental part, the archaeological data on the number of lithic caches on the Japanese Archipelago is impressive – even according to the pre- liminary statistics for the Late Paleolithic- Neolithic (Jōmon) period there is informa- tion about at least 420 features. A total of 316 features at the sites and in the form of separate complexes have clear prove- nance and field documentation. This num- ber will be used for the statistics8 in the current study, and some major sites illus- trated in the text are marked on the map shown in Figure 6. At least 13 caches are recorded in the ar- chaeological literature and reports for the Late Palaeolithic (35 000–16 000 cal BP) – some of them are presented by concentra- tions of tools (axes with polishing edges and trape- zoidal flakes) (Hinatabayashi site, Nagano; Tsuchiya, Tani 2000), but most of these finds consists of raw material (obsidian in particular; Shirataki-Hattoridai 2 site, Hokkaido; Naoe, Suzuki 2007) or preforms of cores (Onbara 1 site, Okayama; Fig. 7.1; Inada et al. 2009), which correlates with the strategy of high- ly mobile hunter-gatherers. The amount of data on lithic caches increases signi- ficantly in the subsequent period of the Stone Age on the Japanese Islands – Jōmon (16 000–2400 cal BP)9. Twenty-three cashes are known for the Inci- pient Jōmon (16 000–10 000 cal PB) and 24 for the Initial Jōmon (10 000–7000 cal PB). Climatic chan- ges and the gradual transition to a sedentary way of life are logically reflected in the evolution of the li- thic technology and hunting gear. This is vividly il- lustrated by the spectacular caches with artistically made spear points (Fig. 7.2; Mikoshiba site, Sonoda site; Hayashi et al. 2008; Tahira, Nohira 2004), large bifacial cores and bifacial tool blanks (Nogawa, Kashiwabara, Sendai-Uchimae, Iwase), and big pol- ished and chipped axes (Fig. 7.3; Hinata Cave, Nana- Fig. 4.

(2010). Knap & keep> Late Palaeolithic-Neolithic caches, Far East 31 tsuguri, Karasawa B site) found in the southern, central, and, especially in the northeastern parts of Honshu Island (Sagawa, Suzuki 2006; Kanomata 2008; Hayashi et al. 2008; Nakamura, Tsuiki 2008; Shimamuro et al. 2009). Another group of caches is represented by compact features with raw material cobbles, preforms of cores and tools, flakes, and instruments (arrowheads, scrapers, knives, adzes, etc.) in special pits directly in the dwellings or near the living areas. In the case of caches with polished axes some specialists suggest their symboli- cal meaning and connection with ritu- al exchange by analogy with stone and shell axes in Island Southeast Asia and Oceania (Kaner, Taniguchi 2017.328). In turn, large bifacial cores and points at- tracted the attention of experts due to the amazing similarity with the artefacts in Clovis caches, and the discussion about the origin of the latter in Solutrean tech- nological complex in Western Europe (Kornfeld, Tabarev 2009). The significant shift to sedentism with the develop- ment of large multi-dwelling settlements in the in- land and, first of all, coastal areas, took place in the Early Jōmon (7000–5400 cal PB). The number of known lithic caches is growing (33), and the over- whelming majority of them are connected with the special pits in dwelling structures – e.g., specialized caches of six adzes at the Minamitashiro site (Kago- shima; Miei et al. 2005), caches with various tools and blanks at the Karasuno-uwadai site (Akita; Shin- kai et al. 2006) and the Ondashi site (Fig. 7.4; Ya- magata; Sato et al. 1990), caches of flakes and raw material (obsidian) at the Shutoyabayashi site (Naga- no) (Kobayashi, Naoi 1982) and the Choshichiyachi site (Aomori; Kurimura et al. 1982). Middle Jōmon (5400–4300 cal PB) was the most comfortable time in terms of climate and variety of biological resources. This is confirmed by various data on population growth, the number and size of settlements along with the evolution of social com- plexity. Therefore, despite the shorter than Initial or Early Jōmon duration, Middle Jōmon presents in- formation on about 137 lithic caches (more than 40% of the total amount) recorded all over the ter- ritory of the Japanese Islands. The variety of caches is connected to the multiplicity of activities of hun- ters, gatherers and fishers, while it also corresponds to local differences in raw material quality and avai- lability. The tradition of caches of bifacial blanks and tools continues in Northeastern Japan, e.g., a cache of 29 items at the Tsukinoki site (Fig. 7.5; Aomori; Ichimachida, Hatakeyama 1983), while the other caches demonstrate the deposits of obsidian cobbles (Obora site, Nagano; Ichizawa et al. 1987) or flakes (Ota site, Akita; Yachi, Osanai 1991)10, adzes (Ka- buttsuppara site, Yamanashi; Yamamoto, Imahuku 1992) or points (Ueshimizu 4 site, Hokkaido; Koshi- da et al. 1991), or even special tool-kits, hidden in clay vessels (Musashidai site, Tokyo and Tsukakoshi- mukoyama site, Saitama; Sakazume et al. 1991). The Late (4300–3200 cal PB) and Final (3200–2400 cal PB) Jōmon sub-periods are characterized by cold- er temperatures, visible decrease in population and a local fragmentation of cultural characteristics, and more than 50% of all the Final Jōmon sites are in northern Honshu. The lithic caching is confirmed by Fig. 5. Russian Far East.

Ivanova, and Yoshitaka Kanomata 32 66 examples at the Late and at least 20 at the Final Jōmon sites from Kyushu in the south to Hokkaido in the north. In terms of content, lithic caches demonstrate the keep- ing of raw materials and flakes (Komakino site, Aomori; Kodama 2006), core preforms and tool blanks (e.g., Ichinohara site, Ka- goshima; Shigemasa et al. 2006), along with caches of arrowpoints and axes/adzes (Fig. 7.6; Fujiishi site Shizuoka, Ahyou 6 Ku site, Iwate; Katsumata et al. 2012; Segawa et al. 2000). Of special interest are caches of neatly polished axes and chisels placed as precious and prestige items in ceramic vessels (Shudainojo site, Akita; Sugawara, Yasuda 1992). This review of the Palaeolithic – Jōmon lith- ic caches clearly shows that these materials are an extremely informative research base. It is clear that the high acidity of far eastern soils prevents the preservation of any orga- nic materials in the caches (bone, antler, wood, etc.), which could represent instruments for knapping and pressure11, leather or bark containers for keeping items, and, in some cases, burial contexts and burial offerings. Despite this, lithic caches illustrate the wide range of technological and behavioural aspects of culture. Conclusions and perspectives The tradition of lithic caches in the Palaeo- lithic – Neolithic of the Far East demonstra- tes their multiplicity (more than 400 cases), high diversity, duration, dynamics, and lo- cal variability. As a historical phenomenon it fully meets the longue durée model requi- rements. In terms of archaeology, we are dealing with the special strategy of storing lithics which were extracted from chaîne opératoire for some time to be kept in a special place with/without subsequent re- turn and use. The further research perspective includes three important directions. First of all, it is necessary to study the ‘biography and ana- tomy’ of lithic caches which suggest the detailed technological analysis of the arte- facts, dating of caching features, raw mate- rial tracking, contextual data, and use-wear study. The last method, for example, can help to fi- gure out if some of the tools were in use right before caching (Kanomata 2010). Secondly, it is extremely important to understand and interpret the functional division of lithic caches. There are several theoretical approaches to this prob- lem in the archaeological literature devoted to the caches in the other regions of the world. For exam- 11 Such instruments are known, for example, for some Clovis caches (Anzick, Richey-Roberts) in North America (Clovis Caches 2014). Fig. 6. Japanese Islands.

Knap & keep> Late Palaeolithic-Neolithic caches, Far East 33 ple, some researchers working with the materials of Pre-Pottery Neolithic B (PPNB) in the eastern Me- diterranean distinguish ’deposits’ (dépôts) composed of a series of homogenous items, ’reserve’ (réserve) comprising a wider, heterogeneous set of selected preforms, and ‘caches’ as a whole package hidden for a specific (secret, ritual, ceremonial) reason (Ast- ruc, Ibáñez, and Gonzalez-Urquijo 2003.70). Ac- cording to another model with the subdivision into functional (stocks) and symbolical (caches) mean- ings, stock includes ’deposits’, ’reserves‘ and ’hoards’ (Barzilai, Nigel Goring-Morris 2007.280). The term ’cache’, for many scholars, is connected to various forms of ritual or ceremonial activities. For example, caches of highly elaborated obsidian bifaces or pris- matic blades in the Maya area (Mesoamerica) may be ’dedicatory caches’ (prior the construction of any sacred building or temple), or ’intrusive caches’ (placed into the existing structure). Both types of caches were prepared for special occasions and with final destination without return (Kunen, Galindo, and Chase 2002). Any of these approaches and mo- dels could be useful for the functional division of the far eastern lithic caches. Third, it may be very interesting and productive to correlate the data on the far eastern region with the neighbouring territories, such as the Korean Penin- sula, where the information of lithic caches is still waiting for the study (Seong 2015), and with the other regions of the world (Near East, Europe, etc.). Recent experience of the comparisons of the Clovis Paleoindian in North American caches, and Solutrean Volgu biface cache in France (Kilby 2018) fully de- monstrates the promise of this approach, so the fur- ther study of the ’knap & keep’ strategy awaits intri- guing continuation. The authors are deeply grateful to Dr. T. Tsutsumi (Asama Jomon Museum, Japan) and Dr. D. Kilby (Te- xas State University, USA) for the chances to observe some important archaeological collections, for advice and priceless comments on the topic of lithic caches. The research was supported by the Russian Scientific Foundation (Project #19-18-00003 “Neolithic Civiliza- tions of Eurasia: Jomon, Japanese Archipelago – Ori- gin, Early Stage, Local Peculiarities”).
