Did any dinosaurs live in Japan?

Perhaps the first question should be "did the Japanese islands even exist when dinosaurs lived?"  I'm discussing this in a bar in Gifu-ken, Japan, and nobody seems to know.

>Japan was originally attached to the eastern coast of the Eurasian continent. The subducting plates, being deeper than the Eurasian plate, pulled Japan eastward, opening the Sea of Japan around 15 million years ago. The Strait of Tartary and the Korea Strait opened much later.

Dinosaurs disappeared around 65 million years ago (?), which means that the land that made Island of Japan was connected to Asia when there would have been dinosaurs.
