Our guide
Lake Inawashiro is the fourth-largest lake in Japan, in central Fukushima Prefecture, south of Mount Bandai. Its other name, Tenkyōko, means “Heavenly Mirror Lake”. It covers about 104 km², is 63 km around and up to 94 m deep, and lies at 514 m above sea level, within Bandai-Asahi National Park.
If you are choosing a season, winter has something the rest of the year does not: swans migrate to the lake's shores and stay until spring. We have not checked a public-transport route to the lake, so plan the journey on the map.
