Another Great Hike in Hinohara Village

Hinohara Village is a popular playground for Tokyoites and includes several noteworthy drawcards including Mt. Mito, and the Odake and Mitsugo limestone caves. I also discovered on this hike it includes a waterfall listed in the One Hundred Waterfalls of Japan, the Hossawa Falls 払沢の滝. Being on the fringes of Tokyo also means its trails are well marked and with most mountains falling under the 1,000 metre ceiling makes them family friendly.

To get to the Hossawa no taki iriguchi bus stop 払沢の滝入口 take a 20 minute bus ride (470 yen) from Musashi-Itsukaichi Station (bus stop 1). It is definitely recommended to make a short detour via the waterfalls which takes around 10 minutes up a dirt path. Best advice is to jump on an early bus to avoid the place swarming with sightseers. After taking in the beautiful cascades return to the road and turn left where there is a sign pointing towards Mt. Sengenrei 浅間嶺. After heading up the road the first marker you should look for is on the left hand side, leading up some stairs (this isn’t the trail head, but a shortcut bypassing a section of road you’re walking). After hitting back onto the road keep heading up and look for a sign directing you to the Tossaka Pass 時坂峠.

Next is another short section of paved road passing by a historic homestead. Shortly afterwards the road diverges so take road on the left and begin the gradual climb up to Mt. Sengenrei. The trail is easy going and after 45 minutes the trail forks with the option of heading directly to the summit or passing via the Sengenrei rest place. Given the top of Mt. Sengenrei (903 m) has terrific views towards Mt. Odake and Mt. Gozen I would suggest making this your lunch spot.

After refuelling with some calories the trail to the Kamigawanori bus stop 上川乗 commences on your left and takes around 50 minutes to reach. On the way down there were several large contingents of hikers making their way up, presumably making the hike in reverse finishing at the waterfall. The 40 minute bus ride (700 yen) back to Musashi-Itsukaichi Station returns via the same Hinohara Road.

  • Start this trail from the opposite end. That way if you have to wait for the bus you will have something to do. A cafe a walk to the falls. On the other end the bus ride is long and nothing there.

  • WARNING!!!!!Also watch out at about half way there is a trail to the left with i think a sign that says itsukaichi kago. The old Samurai trail . It looks like a steep short cut up to the summit. ITS NOT THE TRAIL ENDS SHORTLY ABOVE AND ITS REALLY DANGEROUS. There is not footing. Take the well worn path. i had my dog and daughter and we all almost went tumbling down the side.

  • Hey, thanks for the blog & post. Just a head’s up that the waterfall at the start of the trail freezes in winter and is quite pretty. You can check how much of it is frozen here:, updated daily.

    For anyone going, there is some snow/ice on the top (as of 1/26/2017) which requires a bit of caution, but not necessarily crampons

    • Thanks Tim, well-timed advice. I was actually thinking about making a return trip in the coming weeks, though was hoping for some snow to bump up the frozen look of the falls. Cheers for the link showing what proportion of the falls has frozen – it’s gone from 5% to 65% this past week!

  • Just finished this trail yesterday. I think starting at hossawa falls is a better choice, so you can eat your victory lunch while taking in the view atop Mt. Sengenrei. The instructions above worked for me and the view was def worth it.
