Lake Inawashiro, affectionately known as Tenkyo-ko or Mirror of Heaven, is the fourth-largest lake in Japan, situated in central Fukushima Prefecture at the foot of Mount Bandai. The lake's remarkably clear and slightly acidic water creates clear reflections of the surrounding mountains, particularly the volcanic cone of Bandai. In winter, hundreds of swans migrate to the lake, creating a scenic view against the snow-covered landscape. The lakeshore offers swimming beaches in summer, watersports, and cycling paths, while the nearby Inawashiro Herb Garden provides seasonal flower displays. The area is also the birthplace of Dr. Hideyo Noguchi, the renowned bacteriologist featured on Japan's 1,000-yen banknote, and his memorial museum stands near the shore.

### How do I get to Lake Inawashiro from Tokyo?

Take the Tohoku Shinkansen from Tokyo to Koriyama (about 80 minutes), then transfer to the JR Ban-etsu West Line to Inawashiro Station (about 35 minutes, around ¥510). From the station a local bus runs to the lakeshore in roughly 10 minutes.

### What is Lake Inawashiro known for?

It is Japan's fourth-largest lake and is called "Heaven's Mirror Lake" for the way its water reflects Mt. Bandai. From November to March hundreds of whooper swans winter at Shidahama, and in summer the lakeside beaches are used for swimming.

### Is there an entry fee, and when is the best time to visit?

The lakeside is free and open all year. Come in summer for swimming or from November to March for the wintering swans; the nearby Hideyo Noguchi Memorial Hall charges ¥800 if you want to add it.
