Mt. Daifukuyama

Mt. Daifukuyama (大福山, 292 m) in Ichihara, Chiba Prefecture is the highest peak in Ichihara and one of the 100 Famous Mountains of Kantō. Set in a corner of the Yoro Valley, it is walked together with the scenic Umegase Gorge on a popular hiking course. Highlights are the sheer cliffs 30–50 m high, the great maples of the former Hidaka residence (Umegase Shodō), where the Meiji-era educator Hidaka Sanezane tried to build an ideal community, and the observation deck and Shiratori Shrine near the summit. It is famous for some of the latest autumn colours in Kantō, from late November to early December.
The nearest station is Yorokeikoku Station on the Kominato Railway; from the station you walk up through Umegase Gorge to the summit — a hike completed entirely by public transport.

Mt. Daifukuyama is one of the 100 Famous Mountains of Kantō. The trailhead is reached on foot from Yorokeikoku Station on the Kominato Railway: about 30 minutes from the station to the Umegase Gorge entrance (near the Umegase tea house), and about 2 hours up the gorge to the summit. The usual plan climbs the valley route to the ridge and returns by the paved “lookout road” to the station.

1. [Outbound] Yorokeikoku Station → Umegase Gorge → Mt. Daifukuyama (on foot)

The gateway is Yorokeikoku Station on the Kominato Railway (change to the Kominato Railway at Goi Station on the JR Uchibō Line). Walk south from the station along the paved road to the Umegase Gorge entrance (near the Umegase tea house, the trailhead), about a 30-minute walk. From here the valley route crosses the Umegase River many times on stepping stones, passes the former Hidaka residence (Umegase Shodō) of Hidaka Sanezane and climbs to the ridge, reaching the summit of Mt. Daifukuyama (292 m) about 2 hours from the station. An observation deck stands about 200 m east of the summit, and Shiratori Shrine is at the top. The river can be impassable when in spate, so take care after rain.

2. [Return] Mt. Daifukuyama → the lookout road → Yorokeikoku Station

To descend, take the paved forest road, the “lookout road” (Miharashi-no-michi), down from the summit back to Yorokeikoku Station. Going up through Umegase Gorge and down the lookout road — rather than retracing the valley — makes a varied loop of about 12.6 km and roughly 5 hours of walking. The lookout road is easy paved walking but long, so descend in good time to catch your train.

3. Routes, recommended plans & area info

Standard plan (loop from the station): Yorokeikoku Station → Umegase Gorge entrance → former Hidaka residence → Mt. Daifukuyama (292 m, observation deck, Shiratori Shrine) → lookout road → Yorokeikoku Station, about 12.6 km, roughly 5 hours of walking, with about 400 m of climbing. The valley route has many stepping-stone crossings and slippery rocks, so trekking shoes are recommended.
Shorter plan: a half-day walk going up to the former Hidaka residence and back through Umegase Gorge without climbing to the summit — ideal for autumn-leaf viewing.
