Polyploidy is an important evolutionary mechanism and speciation mode in plants; however, delimitation of species boundaries in polyploid complexes is often a difficult task. In the present paper, we explore morphological variation in a group of East Asian Cardamine polyploids that have long been shrouded in taxonomic and nomenclatural confusion. We relate the present morphometric data of 41 sampled populations with recently published ploidy-level data, and propose a revised taxonomic treatment, including the designation of several lectotypes. The following species are recognised in Japan: C. schinziana O.E.Schulz (2n = 6x, 8x), C. torrentis Nakai (2n = 8x), C. valida (Takeda) Nakai (2n = 4x) and C. yezoensis Maxim. (2n = 6x−12x). C. amariformis Nakai (2n = 4x) from Korea is also discussed, although it may be conspecific with C. valida, pending further studies. Distribution of these taxa in the Japanese Archipelago is characterised, including comments on their occurrence outside of Japan.

Abstract In response to the arrival of Iberian traders and missionaries on the Japanese archipelago in the sixteenth century, local craftsmen developed a unique type of lacquer, called today Nanban, for European export. They adapted traditional techniques to produce chests, writing desks, reliquaries and oratories for this new peripatetic clientele. This paper will explore the assimilation of East Asian lacquered objects within the Iberian world, treating the physical and ontological transformations that occurred as they travelled throughout the vast Iberian mercantile empire in the Indo-Pacific. The very portability of such lacquered objects engendered new realms of artistic experimentation. Like the layered quality of lacquer itself, these mobile works served as vehicles of material assemblage and hermeneutic accumulation, gathering new receptions and identities as they traveled through these Pacific networks and beyond.

Anchitherium (Mammalia, Perissodactyla, Equidae) from the early Miocene Hiramaki Formation, Gifu Prefecture, Japan, and its implication for the early diversification of Asian Anchitherium

An Anchitherium specimen with a nearly complete series of the upper cheek teeth (P2–M3), from the upper part (ca.17–18 Ma) of the Hiramaki Formation, Kani Basin, Gifu Prefecture, Japan, was previously referred to Anchitherium “hypohippoides” nomen dubium. Despite that it provides one of the best examples of significant dental characters of Asian Anchitherium, it has remained undescribed and unprepared until recently. Although a paucity of materials from Asia makes the taxonomy of Asian Anchitherium difficult to assign, comparison showed that the specimen should be reassigned to Anchitherium aff. A. gobiense; it differs from A. aurelianense and is rather similar to A. gobiense from China by virtue of large size and expanded hypostyles. The Japanese Anchitherium also shows distinct features including straight (flattened) ectolophs with narrow mesostyles, rudimentary crochets, and enamel protuberances at the lingual mouth of the median valleys. This combination of accessory features has not been known in Asian Anchitherium and seems to be rarely observed among the diversified European species. The existence of Japanese Anchitherium implies early species diversification in East Asia that predates a greater diversification in Europe associated with the Middle Miocene Climatic Optimum and supports paleogeographical and paleozoological connection to the Asian mainland under a warm and humid climate prior to the formation of the Japanese archipelago (ca. 16.5 Ma).

The ebb and flow of human migration across the planet can nowadays be probed with advanced archaeology, linguistics, anthropology and genomics. Together, these can provide a convincing picture of the various divergences and convergences of different human populations across vast areas. It is now possible to better understand how, why and where a particular group or society arose. Professor Naruya Saitou of the Population Genetics Laboratory at the National Institute of Genetics in Mishima has dedicated his career to the synthesis of these disciplines. The current focus of his research is on understanding the origins and formation of the Yaponesian people. This broad term was coined by writer Toshio Shimao in 1960s to encompass the diverse peoples of the Japanese Archipelago over its many thousands of years of inhabitation. Saitou's research is helping to uncover Japan's ancient past.
