The Tsugaru Peninsula (津軽半島, Tsugaru Hantō) is a peninsula in Aomori Prefecture, at the northern end of Honshū island, Japan. The peninsula projects north into the Tsugaru Strait separating Honshū from Hokkaidō. The western coast is on the Sea of Japan, while on its eastern coast are Aomori Bay and Mutsu Bay. The peninsula is bisected from Cape Tappi at its northern end to the Hakkōda Mountains on its southern end by the Tsugaru Mountains. Across the Tsugaru strait to the north is Hokkaidō's Matsumae Peninsula, to which it is linked by the Seikan Tunnel.

👉 Tsugaru Peninsula in the context of Tsugaru Strait
The Tsugaru Strait (津軽海峡, Tsugaru Kaikyō) is a strait between Honshu and Hokkaido in northern Japan connecting the Sea of Japan with the Pacific Ocean. It was named after the western part of Aomori Prefecture. The Seikan Tunnel passes under it at its narrowest point 12.1 miles (19.5 km) between Tappi Misaki on the Tsugaru Peninsula in Aomori Prefecture, Honshu, and Shirakami Misaki on the Matsumae Peninsula in Hokkaido.
Western maps made prior to the 20th century also referred to this waterway as the Strait of Sangar.

Tsugaru Peninsula in the context of Oshima Peninsula
The Oshima Peninsula (渡島 半島 Oshima-hantō) is the southernmost part of Hokkaidō, the northernmost of the Japanese islands. Where the peninsula starts is open to interpretation. A more generous interpretation is to draw a line southeast from Ishikari Bay across the Ishikari Plain to Yūfutsu District, Hokkaido. A narrower interpretation is to draw a line connecting Suttsu on the Sea of Japan and Oshamambe on Uchiura Bay. This narrow interpretation encompasses the subprefectures of Oshima and Hiyama.
At its southern end it forks into the southwest-pointing Matsumae Peninsula and the southeast-pointing Kameda Peninsula. These two peninsulas face Tsugaru and Shimokita Peninsulas of Honshū across the Tsugaru Strait. The Ōnuma Quasi-National Park is located on the peninsula.
Tsugaru Peninsula in the context of Cape Tappi
Cape Tappi (竜飛崎/龍飛崎, Tappimisaki) is a headland on the northwestern point of the island of Honshu in Japan. The name is believed to be derived from tampa which means "sword's edge" in the Ainu language. It is located on the northern tip of the Tsugaru Peninsula within the borders of the town of Sotogahama in Aomori Prefecture. Much of the cape is also a part of the Tsugaru Quasi-National Park. The cape marks the western limit of the Tsugaru Strait, separating it from the Sea of Japan. The area is known for its almost constant strong winds.
The cape's Tappizaki Lighthouse is listed as one of the “50 Lighthouses of Japan” by the Japan Lighthouse Association. Near the lighthouse are stone monuments commemorating a number of people associated with Aomori Prefecture, including the author Osamu Dazai. On clear days, Matsumae Peninsula in Hokkaido across the Tsugaru Strait can be seen from this location.
