(Ishi-no-Hōden, Japan) A mysterious megalithic stone cut from the surrounding rock quarry. This stone is among the three biggest mysteries of Japan. At present, he is worshiped as the god Ōshiko jinja Shinto Shrine.

Although the top is covered with pine trees, there is reason to believe that there are two holes similar to Masuda-no-Iwafune and Kengoshizuka-kofun.
