Up close and personal
with an active volcano

On the Ebino Plateau, the explosion crater of Mt. Karakuni, the steaming vents of Mt. Iwo, crater lakes like Lake Rokkannon-miike and Lake Byakushi-ike are among the highlights of the volcanic landscape.

Volcanic activity creates
a diverse ecosystem

The Kirishima region is the only location on Earth that is home to nokaido crab apples and the Miyama kirishima Kyushu azalea, which turn the mountainside pink. The diverse landscape hewn by volcanic activity is a rich habitat for flora and fauna.

  • 05 Mt.Iwo Covered in beautiful Miyama rhododendrons in early summer
    From the Mt. Karakuni trailhead: 600m
    Standard time
    From the Mt. Karakuni trailhead: 20 mins

    This peak is located at the east of Ebino Plateau, relatively close to the road.
    The mountain has a yellow or sulfur-yellow hue, due to the emission of volcanic gases containing hydrogen sulfide and sulfites up to about 20 years ago.
    From the Meiji period to the mid-1950s, sulfur was mined here for the production of matches, and the fume vents from the mining can still be seen today.
    Vegetation is returning now that the volcanic gases have stopped venting.
    In early summer, Kyushu azalea beautify the slopes of the mountain, making this a popular stop.
    Due to the eruption in April, 2018, refrain from approaching the crater.


    Also known as Sai-no-Kawara, the rocks in the area around the summit are whitened by the fumes emitted from the volcano.
    It is a one-hour return journey from Ebino Plateau, with beautiful views on a fine day.

    This mountain is renowned as the spot where the grandson of the Sun Goddess is said to have descended to earth from the heavens in the first stage of "Tenson korin," an episode in Shinto mythology. The mountain is expressive of the character of the Kirishima mountain range, in both its historical associations and the formation of the mountain itself. With vegetation scarce on the mountainside, the reddish-brown earth presents a constantly-changing panorama of color from morning to evening.
    The summit of Mt. Takachihonomine features "Amanosakahoko," a legendary spear which features in the "Tenson korin" of Shinto mythology.
    Over the New Year period, the peak of the mountain is busy with people who come to watch the first sunrise of the new year from the summit.
    The mountain is also a much-loved spot in early summer, when its slopes are bright with flowering azalea.

    Mt. TakachihonomineHighlights

    Visitors can currently observe the mountain covered in lapilli, a kind of volcanic rock that was brought forth by the eruption of Mt. Shinmoe at the end of January 2011. As there is almost no plant growth on the mountain's slopes, insects buoyed up by upward air currents can be seen swarming around the peak of the mountain in large numbers, a phenomenon that cannot be observed anywhere else in the Kirishima mountain range.

  • 12 Lake Miike A great spot for birdwatching
    Standard time
    1h 30

    The deepest crater lake in Japan at 1km across, 4.3km in circumference and 103m deep, Lake Miike was created by a
    phreatomagmatic eruption which took place around 4,600 years ago. The pumice stone which is produced when eruptions occur is also known as "lake earth" in Japanese; large deposits of this have long been found in in Takahara-cho and are currently seen in the center of Miyakonojo as well.
    There are seven ports on the lake: Matsu Port, Mukurasemi Port, Oji Port, Urugizaki Port, Karukaya Port, Yanagi Port and Gomadan Port. Oji Port ("The Prince’s Port"), which currently has a boat platform, is said to have acquired its name from the legend that Emperor Jinno, the first emperor of Japan, played on the shore here as a young child.
    There is also a legend about a "shinryu" (divine dragon) associated with this lake. According to "Sangoku Meishozue" (Geography of Southern Kyushu), a book about scenic spots written in 1843, a priest called Shoku Shonin (910–1007), who established a mountain temple in Mt. Kirishima, described how a nine-headed divine dragon appeared to him while he was engaged in religious training on the banks of the river, whereupon Shoku offered a jewel to the dragon.

    Lake MiikeHighlights

    The National Lake Miike Wild Bird Forest centered on the lake attracts birdwatchers in every season of the year.
    The lakefront also features a campground, and waterfowl such as Mandarin ducks, common teal and Baikal teal are among the many birds that are found here.


SPRING Colorful wildflowers and birdsong on the plateau

Japanese witch hazel (hamamelis) and fragrant witch hazel (Corylopsis glabrescens) start to bloom and cover the mountain slopes in yellow, signaling the start of the active season for animals. Woodpeckers tap away at the trunks while small birds reveal beautiful birdsong at the treetops.

SUMMER The season of the rhododendron that symbolizes Kirishima

Early summer is the season of the Rhododendron kiusianum, the most famous flower of the Kirishima area. The song of the cuckoo rings out all over the Ebino Plateau. This is the busiest season for wildlife. In midsummer the cool breeze of the plateau is most pleasant, making this the perfect getaway from the heat everywhere else.

AUTUMN The dazzling contrast of autumn foliage and crater lakes

Look up at the beautiful leaves. At your feet, the colorful blooms of the Japanese gentian and assorted mushrooms. In the evening, the roar of stags pierces the silence across the plateau. The azure crater lakes contrast beautifully with the forest that surrounds them.

WINTER A frozen silver landscape

The season of the rime ice that creates artistic natural forms. The frozen vista from the top of Mt. Karakuni is breathtaking for its cold and its beauty. The serene hush of the early morning is so quiet you can hear your own heartbeat.
