This paddy is absent due to uncultivation.
A Landscape of Traditional Paddy in Kii Oshima island in Southern Honshu of Japan in 1999.

Rich plant diversity in Himalayan Highlands in Yunnan, China. There are numerous flowers and landraces of cultivated plants near dwellers' hamlets.

RESEARCH SUBJECT:
　My research major is plant biodiversity at past, present and future in the levels of gene, individual, population, species, community and landscape analyzed by bioscience technology for human beter life and sustainable utilization of plant genetic resources and for development of new crops with harmonies of living organisms.
