Mt. Kurikoma (Kurikoma-yama) is located in the center of the Tohoku region, where the borders of Miyagi, Iwate and Akita prefectures meet, and is selected as Kurikoma Quasi-National Park. It is an active volcano, and fumarolic activities can be observed in various spots of the mountain today. Out of nine trailheads, this route introduces the traverse route that originates in Iwakagami-daira, which is on the Miyagi prefecture-side and has convenient access. It continues on to the summit of Mt. Kurikoma, and comes down to Sukawa Onsen hot spring on Iwate prefecture-side through the Ubu-numa course via Ubu-numa Swamp, Sanzuno-kawa River and Nagorigahara Wetland.

From Iwakagami-daira, take the Higashi-kurikoma course that separates from the main course. Proceeding along the swampy trail and over the ladder-equipped rocky section, the trail enters a shrub zone. After a total of about 40 minutes of hiking, you will arrive at Shin-Yuzawa.

Hiking up the rocky section of the riverbed along the swamp for about 100 meters, the trail turns back to shrub zone with a steep slope. The surrounding area changes to creeping pine belt and shrubs in a grassy plain, which opens wide as you continue on.

Mt. Higashi-Kurikoma (Higashi-Kurikoma-yama) is about 20 minutes away from Shin-yuzawa, and about 30 minutes more to the Higashi-Kurikoma fork. The trail continues on through a gently sloping grassy field, and turns into wooden stairs. It takes about 30 minutes to Mt. Kurikoma.

To get to Sukawa Onsen, descend Ubu-numa course (nature observation course) via Ubu-numa Swamp, since the route via Lake Showa (Showa-ko) is off-limits due to hydrogen sulfide gas eruption. Descend the trail with small bamboo and grass growing thick for about 40 minutes, and you will arrive at Ubu-numa Swamp.

Take a left at the fork and descend for approximately 30 minutes, and cross a stream called Sanzuno-kawa River, which name comes from Japanese mythological river that is believed souls must across after physical death.

Traverse on a small ridge for approximately 15 minutes, and you will arrive at Nagorigahara Swamp. Continue hiking on a flat wooden walkway through a grassy field and descend through a shrub zone, and you will get to Sukawa Onsen in about 20 minutes.

Other Info

Though the beauty of alpine plants that blossom from July to August cannot be missed, Mt Kurikoma is the busiest with many hikers during the autumn foliage season, which is from late September to mid-October. The combination of colors consisting of red and orange of trees such as nanakamado (Japanese rowan) and the green of creeping pine and bamboo leaves, adorns the entire surface of the mountain, earning the alias of “divine carpet.“ Nagorigahara grass field also pleases visitors’ eyes with golden autumn foliage.

High Season:June to October


The Higashi-Kurikoma route introduced in this course will become a stream when it rains due to its swampy geographical feature. There are wet places that need to be crossed so hiking from the main route is recommended when raining.
