The Inawashiro Lake area of Bandai-Asahi National Park is Inawashiro-ko, where the parental home of Hideyo Noguchi (1876–1928) can still be found. It was preserved along with some of Noguchi's belongings and letters as part of a memorial. Noguchi is famous not only for his research on yellow fever, but also for having his face on the 1,000 yen note.
