Sakafune-ishi Ruins is a vast granite slab about 1,300 years old, with straight channels feeding into round basins. “Sakafune-ishi Ruins,” or “sake boat stone,” is a nickname, not a translation. It belongs to a group of at least a dozen carved Asuka-region stones, and archaeologists still debate whether it was a water-filtering system or something else.
