This is a bench located in Botsu-cho, Minamisatsuma City, Kagoshima Prefecture, where the movie "You Only Live Twice" was filmed.
The table is shaped like a wine glass, and you can take photos at sunset with the setting sun appearing in the glass.
There is also a memorial hall for Jianzhen, a historical figure, near the monument, so it seems like a good place to stop by and take a break during your touring trip.
