Cape Tappi, Remote cape in Sotogahama, Japan

Cape Tappi occupies the northwestern tip of Honshu island and marks where the Tsugaru Strait meets the Sea of Japan at its western edge. The rocky shoreline features the Tappizaki Lighthouse, which stands as a prominent structure overlooking the coastal waters.

The cape's name is traced to the Ainu word tampa, "sword's edge", though a folk etymology links it to the strong winds that "make dragons fly". An older layer of legend ties the place to Minamoto no Yoshitsune, who according to the tradition preserved at the Gikei-ji temple of Ryūma-yama fled from Koromogawa to this shore and crossed to Ezo on horseback. The cape lies within Tsugaru Quasi-National Park.

Near the lighthouse stand monuments to Osamu Dazai, the poet Yoshida Shōin, the writer Ōmachi Katsuki and the haiku poet Kawakami Santarō. A button on the Tsugaru Kaikyō Fuyugeshiki song monument plays one verse of the enka sung by Sayuri Ishikawa. The former Okuya inn, where Dazai stayed, now serves as the Ryūhikan tourist information office.

Reaching this remote location requires personal transportation, as public transit options are limited in the area. Visitors should prepare for winding roads and variable weather, particularly during colder months.

Route 339 includes a stretch of steps at Cape Tappi, so the national highway is walked rather than driven. The cape's ridge also carried eleven wind turbines of the Tappi Wind Park, a power facility that was shut down at the end of March 2007.
