My name is Haruka Mizuno and I guide walkers in snow country. I live in Yamanouchi, the town Jigokudani Yaen-koen sits in, and this site is mine. It is independent. The park does not run it, has no say in it, and is not responsible for anything on it.

Why I write it

I have walked the path from Kanbayashi Onsen up to the park in every month of the year. In August it is a warm half-hour through the forest and you arrive with damp hair. In late January the same 1.6 km is packed snow over a slope, and the last stretch before the gate is the steepest part of it. I have stood at the trailhead and watched a family set off in city trainers, carrying a toddler, at four in the afternoon in February.

People arrive here having read a great deal about the monkeys and almost nothing about getting to them. The photographs travel; the bus timetable does not. So the pages here spend their time on the journey: the shinkansen and the bus, the walk itself, the cold, and which months actually produce the bathing behaviour you came for. The monkeys are the straightforward part.

What this site is not

I am not the park. Jigokudani Yaen-koen runs its own website at en.jigokudani-yaenkoen.co.jp, and that is where official answers live: opening hours, the rules, and the live update on whether the monkeys have come down that day. If what I write ever disagrees with the park, believe the park.

I do not sell admission either. Entry is ¥800 for an adult and ¥400 for a child aged 6 to 17, paid at the park, and none of it comes through me. The park has announced an online ticketing system from late August 2026; when it arrives, it will be run by the park, not by this site. What the day costs in total is set out on the cost page.

I am not a tour operator. I have no vehicles, no drivers and no seats of my own. The booking panels on the tour pages belong to GetYourGuide; if you book through one, your booking is with GetYourGuide and the company running the tour.

How the site is paid for

When a booking is made through a link or a panel here, GetYourGuide pays me a commission out of its own margin. The price you pay is the price you would pay booking on GetYourGuide directly. There is no surcharge and no booking fee at my end. The detail is on the affiliate disclosure page.

Being plain about what that changes. It gives me a financial interest in you booking a tour, and you are entitled to read every sentence I write about tours with that in mind. What it cannot touch is the factual layer of the site. Jigokudani is about 250 km from Tokyo, the walk in is 30 to 35 minutes each way, the gate price is ¥800, and the monkeys bathe most reliably in the coldest months. Those numbers do not move for my convenience.

It also has not stopped me writing the obvious thing: assembling the trip yourself, by shinkansen and local bus, is entirely possible and costs less than booking a seat on a tour. Plenty of people should do exactly that, and the page that compares the two says so in as many words. A tour buys timing, transfers and someone who knows whether the trail is ice today. If you do not need those things, keep your money.

One consequence you will notice: where a tour price would normally sit, you get a live booking panel instead of a figure. Prices and departure dates change through the season, and a number I typed last winter would be wrong by the time you read it.

Corrections

Bus timetables change, the park adjusts its hours between summer and winter, and the ticketing system is due to change too. If a page here has gone stale or has something wrong in it, tell me and I will fix it: contact.
