Japanese follows English. 英語の後に日本語が続きます。

This is prunus lannesiana 'Hisakura' or commonly Ichiyo cherry in the Tokyo National Museum. I thought the cherry blossom season had been over, but they were still in bloom with many buds. Ichiyo cherry🌸 is a member of the sato-zakura or sato cherry group. The mother of the group members is all Oshima cherry.
