Kirishima Mountains
霧島山きりしまやまKirishima-yamaA field of volcanoes where Japanese myth places the descent of the gods.
The Kirishima Mountains (霧島山) are a group of more than twenty volcanoes on the border of Kagoshima and Miyazaki prefectures, whose highest peak, Karakuni-dake, reaches 1,700 m. Takachiho-no-mine, where the grandson of the sun goddess is said to have descended to earth, and the active Shinmoe-dake make it both a sacred and a closely watched landscape.
Overview
The Kirishima Mountains stretch about 20 km from the Ebino plateau in the north-west to Takachiho-no-mine in the south-east, a cluster of cones, craters and crater lakes on the border of southern Kyūshū's two prefectures. Karakuni-dake is the highest; from its summit, on clear days, Sakurajima and Kaimon-dake appear to the south.
Kirishima is one of the places where Japanese mythology locates the Tenson kōrin, the descent of Ninigi-no-mikoto, grandson of the sun goddess Amaterasu, to rule the land. Kirishima Jingū at the foot of Takachiho-no-mine commemorates this, and the area was among Japan's first national parks in 1934. Hot springs such as Kirishima Onsen, Ebino Kōgen and Hayashida lie around the massif.
Landscape and formation
The Kirishima volcanoes lie on the rim of the Kakutō caldera and have been active for several hundred thousand years. The group includes stratovolcanoes (Karakuni-dake, Takachiho-no-mine), maars and crater lakes such as Ōnami-ike, and the young, steep crater of Shinmoe-dake.
Historic eruptions have come mainly from Ohachi (next to Takachiho-no-mine), Shinmoe-dake and Iōyama on the Ebino plateau, which erupted in 2018 after a quiet interval of more than 200 years.
Highlights
Karakuni-dake

Takachiho-no-mine
高千穂峰Takachiho-no-mine1,574 m, the sacred peak of the heavenly descent, crowned by the Ama-no-sakahoko halberd.
Shinmoe-dake
新燃岳Shinmoe-dakeThe active volcano whose 2011 eruption filled its crater with lava.
Ōnami-ike

Ebino plateau
えびの高原Ebino kōgenA highland at about 1,200 m with crater ponds, pampas grass and the main visitor centre.
Ecology
Kirishima's volcanoes carry a sequence from evergreen broadleaf forest to deciduous forest and, near the summits, azalea shrubland. The Miyama-kirishima azalea takes its name from these mountains.
Flora
Miyama-kirishima
ミヤマキリシマmiyama-kirishimaThe azalea named after Kirishima, colouring the upper slopes pink in May and June.

Fauna
Sika deer
ニホンジカnihonjikaCommon around the Ebino plateau, where they are easily seen.

Culture
The Kojiki and Nihon Shoki place the descent of Ninigi-no-mikoto on "Takachiho peak in Himuka", identified with Takachiho-no-mine (the other candidate is Takachiho in northern Miyazaki). Kirishima Jingū, rebuilt several times after eruptions, stands at the south-western foot. Shugendō flourished here in the Middle Ages under the monk Shōkū. In 1866 Sakamoto Ryōma and Oryō visited, and Ryōma's letter describing the climb and the Ama-no-sakahoko is famous.

Practical notes
- Access to individual peaks changes with volcanic activity; the Japan Meteorological Agency and Kirishima city publish current restrictions.

- Scoria slopes are slippery; boots with good grip are advisable.
Frequently asked questions
Which Kirishima peaks can be climbed?
Access depends on the activity of individual volcanoes. Takachiho-no-mine from Takachihogawara and, when open, Karakuni-dake from the Ebino plateau are the classic ascents; trails near Shinmoe-dake and Iōyama are frequently closed. Check the Japan Meteorological Agency and the local authorities.
What is the Ama-no-sakahoko?
An ancient bronze halberd planted upside down on the summit of Takachiho-no-mine, associated with the myth of Ninigi-no-mikoto's descent from heaven.
When did Shinmoe-dake erupt?
Shinmoe-dake had a major eruption in 2011, with explosive activity and a lava dome that filled its crater, and further eruptions in 2017 and 2018.
Why is Kirishima linked to Sakamoto Ryōma?
In 1866 Sakamoto Ryōma and his wife Oryō travelled to Kirishima to recover from his wounds – often called Japan's first honeymoon – and climbed Takachiho-no-mine.
