Abstract：Gas hydrate researches in adjacent sea regions around Japan especially on Nankai Trough are introduced.First，history，plans，teams and early results of gas hydrate researches in Japan are introduced.Second，gas hydrate exploration and drilling results on the slope of western Nankai Trough are presented.Third，gas hydrate exploration and drilling results on the slope of eastern Nankai Trough by five-year plan are presented.At last it is pointed out that comprehensive research of new geophysical，geochemical and geological data on Nankai Trough will make new contribution to gas hydrate research in the world.
Keywords：Gas hydrates；Japan；Nankai Trough
