The concept of the Mesolithic/Neolithic transition is difficult to apply in the Japanese archipelago. The earliest pottery usage occurs in late Palaeolithic contexts. Holocene foragers lived in stable, permanent village settlements and constructed large scale monuments, and the first real ‘agriculture’ arrived as part of a cultural package which also included metallurgy. This paper will examine the use of the term ‘Neolithic’ in the history of Japanese archaeology, with particular emphasis on what happened in the western part of the archipelago in the latter part of the Jomon period (c. 5000 BC – c. 500 BC). Recent investigations in Kyushu and Western Honshu are leading to a re-assessment of the nature of Jomon culture and society in this region, traditionally considered to have ‘lagged behind’ the more developed societies of the eastern part of the archipelago, expressed in part through much lower population densities.

AbstractThe generation of the high species diversity of insects in Japan was profoundly influenced by the formation of the Japanese Archipelago. We explored the species diversification and biogeographical history of the Nemouridae family in the Japanese Archipelago using mitochondrial DNA and nuclear DNA markers. We collected 49 species among four genera: Indonemoura, Protonemura, Amphinemura and Nemoura in Japan, China, South Korea and North America. We estimated their divergence times—based on three molecular clock node calibrations—using Bayesian phylogeography approaches. Our results suggested that Japanese Archipelago formation events resulted in diversification events in the middle of the Cretaceous (<120 Ma), speciation in the Paleogene (<50 Ma) and intra-species diversification segregated into eastern and western Japan of the Fossa Magna region at late Neogene (20 Ma). The Indonemoura samples were genetically separated into two clades—that of Mainland China and that of Japan. The Japanese clade clustered with the Nemouridae species from North America, suggesting the possibility of a colonisation event prior to the formation of the Japanese Archipelago. We believe that our results enhanced the understanding both of the origin of the species and of local species distribution in the Japanese Archipelago.

In the summer of 1953, the small village of Yukamura in Okayama Prefecture, Japan, became a major archeological site. The excavation of the Tsuki-no-wa tomb (created in late 4th — early 5th century) was initiated by the local residents with no professional training in archeology. The project became one of the most ambitious and successful endeavors of the People’s History Movement (kokumin-teki rekishigaku undo) led by the Marxist historians in early 1950s in Japan. The “memory” of the excavation has been meticulously documented in scientific papers, tourist pamphlets, individual memoirs, as well as in the film. A short documentary, The Tsuki-no-wa Tomb (1954), was created at the behest of the people involved in the project. While the film was favorably received by the critics, the Minister of Education refused to grant it with an official “recommendation.” Today the short documentary is considered a symbol of the political and cultural mainstream, which adheres to the ideas of social equality and democracy, the importance of a scientific approach, the concept of the “monoethnic” origins of Japan, and the symbolic status of the emperor. In this paper, the paradoxical role of the Japanese leftists in supporting the dominant worldview is examined though the study of The Tsuki-no-wa Tomb. Through analyzing the cinematic text, as well as the history of its production and reception, we come to a better understanding of the ideological and organizational underpinnings of the People’s History Movement, illuminating the film’s role in the development of historical science and documentary filmmaking in postwar Japan.

A series of heavy rainfalls hit the western half of Japan from June 28 to July 8, 2018. Increased river water overflowed and destroyed river banks, causing flooding over vast areas. In this study, two pre-event and one co-event ALOS-2 PALSAR-2 images were used to extract inundation areas in Kurashiki and Okayama Cities, Okayama Prefecture, Japan. First, water regions were extracted by threshold values from three-temporal intensity images. The increased water regions in July 2018 were obtained as inundation. Inundated built-up areas were identified by the increase of backscattering intensity. Differences between the pre-and co-event coherence values were calculated. The area with decreased coherence was extracted as a possible inundation area. The results of a field survey conducted on July 16, 2018 were used to estimate the optimal parameters for the extraction. Finally, the results from the intensity and coherence images were verified by making comparisons between a web-based questionnaire survey report and the visual interpretation of aerial photographs.
