Sightseeing in Hinohara and Akiruno

Mt. Mito, One of the Three Mountains of Okutama

As the name “the three mountains of Okutama” indicates, there are three peaks at the headwaters of the Akigawa-River. These mountains straddle Okutama Town, Hinohara Village, and Uenohara-shi and Kosuge-mura, Kitatsuru-gun in Yamanashi Prefecture. Mt. Mito boasts a height of 1,531 meters (5,023 feet). This mountain is popular because it is the only place in Tokyo where you can see a virgin beech forest. The view from the summit is amazing, and you can see Mt. Fuji, Mt. Kumodori, the Okuchichibu Mountains, and the Tanzawa Mountains, among others. Mt. Mito, Mt. Otake (1,267 meters/4,157 feet), and My .Gozenyama (1,405 meters/4,610 feet) are collectively referred to as “the three mountains of Okutama.” If you climb Mt. Mito by using the Beech Trail (Buna no Ji), which passes by Mitoodake Falls, you can reach the summit in about 1 hour and 55 minutes. This trail, which passes by Mitoodake Falls, a large waterfall with a height of 35 meters (115 feet), is very popular.

Hossawanotaki Falls, One of Japan’s 100 Best Waterfalls

Hossawanotaki Falls is the only waterfall in Tokyo to have been selected as one of the 100 best waterfalls in Japan. It is located in the back regions of the headwaters of Akigawa-River, and has a total height of 62 meters (203 feet) in four steps. Only the bottommost step, with a height of 23.3 meters (76 feet) can be viewed from the trail. The deep pool at the bottom of the last step of the falls is shrouded in mystery, and according to an ancient legend, a giant snake lives there. Hossawanotaki Falls is also famous because it freezes beautifully in winter. The falls are located approximately 15 minutes from the parking lot, which is about a three-minute drive from the Hinohara Village Office.

Hassawa Falls


Kanotoiwa is a large stone peak that was formed by the clear, running water of the rivers that run past it on either side. Because the rock that composes the canyon and the stone wall is of the chert strata formed during the Jurassic period, it is resistant to the erosion caused by wind and rain. This is thought to be the reason that Kanotoiwa remains, towering over the rivers in the canyon. The name Kanotoiwa means “Gods’ door rock.” This name is said to originate from the fact that the rock, when viewed from below, looks like a stone door being opened, which calls to mind the legend of Amano Toiwa, the cave in which the sun goddess hid. In addition, because Ootake Shrine is located above the rock, people say that this is the entrance to the sacred realm of the gods, and that Kanotoiwa serves as the door to the sacred realm. To get to Kanotoiwa, take a bus from Musashi Istukaichi Station. After about a 35-minute bus ride, get off at the Kanotoiwa Iriguchi bus stop. Kanotoiwa is about a 30-minute walk from the bus stop.


Mt. Sengenrei

Mt. Sengenrei, with a height of 895 meters (2,936 feet), is a mountain in Hinohara Village. On a sunny day, you can see Mt. Fuji from the peak. There are also many double-flowered cherry trees on the peak, and in the spring when the flowers bloom, many visitors come to see them. The Sengen mountain ridge was formerly used as a trading road for daily goods such as charcoal, rice, and salt, and is said to have been the main street for the distribution of goods and for the villagers’ daily lives. Stone buddhas alongside the gently sloping road serve as reminders of this history even today. You can walk along the ridge road, which is also a part of the History Trail (Rekishi no michi), one of the Tokyo area nature trails. From the trail, you can see a brilliant view of the mountains of Tanzawa and the mountains of Okutama, such as Mt. Gozenyama and Mt. Otake. A bus, operated by the Nishi-Tokyo bus company, can take you directly to Mt. Sengenrei from JR Musashi Itsukaichi Station. Get off the bus at the Sengen-One Tozanguchi bus stop.

In the past, most people in Hinohara Village grew crops for their own consumption, and each family cultivated crops on a small scale. Recently, however, the village has started renting farmland that previously lay fallow as a result of the aging population and damage caused by animals. This farmland is now used for the village’s “weekend farmer” program, which serves the needs of people who want to work with the soil, and leads to further interaction with people from the city center. Potatoes, which grow in well-drained fields, as well as processed foods and specialty dishes made from potatoes, and helping to increase the output of this farmland. The official village character, Hinojaga-kun, is also based on the image of a potato.

In Hinohara Village, where 93% of the area of the village is forested land, forestry has always been a vital source of livelihood. Many villagers work in the forestry industry. Although the market for wood is sluggish these days because the price of wood has fallen, the people of Hinohara Village have found other uses for wood outside of construction, and have been working to present “Hinohara wood” as a high-quality brand, by utilizing a system that allows the buyer to see the face of the person who cultivated the wood. The village is also making efforts in arboriculture, utilizing the treasures of the mountains, where many trees reach cutting age, to examine the calming effects of trees and to contribute to education.

Hinohara-Shikino-Sato: A Restaurant Featuring Local Cuisine Made with Local Ingredients

Hinohara-Shikino-Sato is a restaurant where you can enjoy homestyle cuisine featuring home-grown vegetables from Hinohara Village. In Hinohara, vegetables come into season slightly later than they do in central Tokyo, and they are grown in small fields on steep slopes. Great care is taken to use these vegetables, as well as the precious mountain vegetables that are gathered in the mountains. The restaurant specializes in meals that allow diners to experiencing Hinohara as it is now, rather than using early ingredients from the coming season. The maitake mushrooms used here are cultivated by the Hinohara Kinoko Center (Hinohara Mushroom Center) at an altitude of 840 meters (2,756 feet), where the temperature is maintained at about what it is in Hinohara Village in October. This allows the restaurant to use not only wild mushrooms, but also mushrooms cultivate locally.
