Mt.Sakaigatake・Sekimon A pristine forest where Hahajima’s rare animals and plants still remain
This is a special protection zone within the national park, and also a Forest Ecosystem Reserve of Hahajima’s east coast, designated by the Tokyo Regional Forestry Office of the Forestry Agency.
Visitors must be accompanied by a guide certified by the Tokyo Metropolitan Government to enter the forest.
It is a pristine forest where moist-tall shrubs mainly grow.
Extremely rare endemic plants only found on Hahajima, such as the Sekimon tree (claoxylon centinarium), Oyama Ichijiku (ficus iidaiana), Sekimon Raisou (Procris boninensis), and Taiyo Futo Kazura (piper postelsianum) are found.
Sharply jagged rocks called lapies can also be seen in the forest, as it is a limestone district.
An hour away from the entrance and along the way to Sekimon is the summit of Mt. Sakaigatake (elevation of 444m).
*Make sure to join a guided tour if you wish to visit the forest. According to Hahajima’s local regulation, entry to the Sekimon area is prohibited between October and February, which is the breeding season of the endemic red headed wood pigeon. Only the ridge trail becomes open in March.
The Hahajima Tourist Association issues a memorial certificate for climbing to the top of Sekimon (300 Yen).
Please apply at the Hahajima Tourist Association desk before climbing if you wish to order one.
