The Kawaguchiko Music Forest is a charming little theme park and museum all about musical instruments. Visitors can check out antique music boxes, mechanical organs, and other cool musical contraptions from Europe. The highlight is a massive French fairground organ from 1905 that plays every half hour. Outside, you can stroll through European-style gardens with a view of Mount Fuji across the lake. It's a fun spot to explore for music lovers and anyone looking for a unique experience in the Fuji Five Lakes area.
