Oshino Hakkai, also known as the Eight Seas of Oshino, is a charming village in Yamanashi Prefecture, Japan, famous for its eight picturesque ponds fed by melted snow from Mt. Fuji. Visitors can stroll around the tranquil ponds, admire traditional thatched-roof buildings, and enjoy views of the iconic mountain. The village offers a peaceful retreat year-round, with maple trees turning amber in autumn and snow adding a magical touch in winter. Don't miss the gift shop selling Mt. Fuji-themed souvenirs and local treats like kusamochi—a green rice cake filled with sweet red bean paste.
