Aomori's Absolute Essentials

Aomori features a diverse landscape ranging from the volcanic terrain of Osore Yama, one of Japan’s most sacred sites, to the ancient beech forests of the Shirakami-Sanchi UNESCO World Heritage site. The region includes Lake Towada, Honshu’s largest crater lake, and the historic Sukayu Onsen, known for its massive wooden bathhouse. Cultural landmarks like the Tsugaru clan’s Chosho-ji Temple and the Iwakiyama Shrine complement engineering feats like the Seikan Tunnel, which connects Honshu to Hokkaido beneath the Tsugaru Strait.
