SIGHTSEEING SPOT
Mt. Mihara

Mt. Mihara

Having been both worshiped and feared by local people from ancient times as “Gojinka-sama” (God of fire), Mt. Mihara is considered one of the world’s top three liquidity volcanoes. An active volcano, the mountain has repeatedly erupted since more than 15,000 years ago, changing the shape of the island each time. From a walking trail around the crater you can see up close the volcanic fumes and vestiges of the past eruptions.

Motomachi Hama-no-yu

Motomachi Hama-no-yu

Hama-no-yu is an open-air hot spring facility using hot springs that gushed out after Mt. Mihara’s eruption in 1986. It offers splendid views of the Pacific Ocean in front of the bath and Mt. Mihara on the back side.

Tsubaki Tunnel

Tsubaki Tunnel

Located in Sentsu close to Oshima Park, Tsubaki Tunnel is a camellia-lined street that represents Oshima, an island famous for camellias (tsubaki in Japanese). The camellias were planted for about 100 meters along both sides of a road circling the island. The trees are about 200 years old and create a natural tunnel.

Oshima Park

Oshima Park

Oshima Park is a natural park making full use of the great natural environment of the island, with a total land area of 3,270,000 sqm. It has a zoo and a camellia grove, which is one of the largest such groves in Japan. A walking trail stretches along the beach nearby. A camping site is also available at “Umino Furusato Mura” in the south to the park.

Senba Stratum Section

Senba Stratum Section

Senba Stratum Section is a geological cross section running 600 meters and discovered in 1953 when a road construction project between Motomachi Port and Habu Port was under way. Well over one hundred eruptions of Mt. Mihara have created 90 layers of strata with a tremendous amount of volcanic ashes. Because of its wavy layers, called “Baum kuchen” by local people, it creates a unique landscape.
