Nagano Prefecture, in the center of Japan’s Honshu island, is known for its mountains, hot springs and architecture. The capital, Nagano, is home to 7th-century Zenkō-ji temple, with a hidden Buddha statue whose replica is shown publicly once every 6 or 7 years. Its 16th-century Omine Castle is now a butterfly museum. The Togakushi district has ancient Togakushi Shrine and weapons at Togakushi Ninja Museum.
