Why Mitsukejima
Mitsukejima is an uninhabited islet situated in the town of Takadate-cho within Suzu, a municipality in Ishikawa Prefecture, Japan. Historically recognized for its distinct silhouette, the site earned the alternative name Gunkanjima, or Battleship Island, a moniker shared with Nagasaki's Hashima Island. The island serves as a prominent scenic destination within the boundaries of Noto Hantō Quasi-National Park.
According to regional folklore, the location received its name from Kūkai, a famed Buddhist monk, artist, and scholar. Local tradition states that he was the first person to spot the island during his travels from nearby Sado Island.
Geographically, the island spans roughly 150 meters in length and 50 meters in width, rising to an elevation of approximately 30 meters above sea level. Its geological composition consists of diatomaceous earth from the Neogene period. This specific mineral material is traditionally harvested in Suzu to manufacture shichirin, which are local portable clay cooking stoves. The upper surface of the island supports vegetation primarily comprising Japanese black pine and Japanese knotweed.
Mitsukejima has faced significant physical changes due to seismic events in the region. Local observers recorded landslides on the island during an earthquake in 2023. A subsequent major earthquake in 2024 caused additional large-scale landslides, altering the terrain and leading to the loss of its signature battleship-like shape. Following this event, local authorities in Ishikawa Prefecture announced plans to create a virtual 3D scan of the island for tourism purposes.
In addition to its natural and historical aspects, the location holds a place in contemporary Japanese culture. Mitsukejima was depicted in the manga series Insomniacs After School, created by Makoto Ojiro, as well as in its media adaptations.
