About this spring
A wild mountain onsen deep in Kurikoma Quasi-National Park in Iwate Prefecture, founded in 1134. Seven outdoor bathing pools sit along a rocky riverbed with no walls between you and the forest. The water bubbles up directly from the riverbed and banks. Access is closed from mid-November through early May when the mountain road is buried in snow.

History
Geto traces its origins to 1134, making it one of the oldest established hot spring retreats in Tohoku.
The founding legend speaks of a warrior whose descendants discovered the springs with the help of a giant white ape. In the Edo period the spring was formally ranked as the eastern ozeki in Japan's official hot spring assessments, second only to the highest rank, placing Geto among the most esteemed baths in eastern Japan. Today the site is recognized as one of Japan's Top 100 Famous Hot Springs.
Local guide
To reach Geto Onsen from Kitakami, you drive north on a road that climbs steadily into Kurikoma Quasi-National Park, passing through tunnels of beech trees until you cross a small bridge and arrive at a cluster of low wooden buildings beside a mountain stream. The access road closes in November and does not reopen until May, which means the entire place hibernates under snow for half the year. If you arrive in late spring, just after the road reopens, the beech leaves are still a bright yellow-green, and snowfields remain on the upper ridges above the valley.
Geto Onsen was founded in 1134, which makes it one of the older operating hot springs in the country, though the buildings themselves are modest and functional rather than grand. The spring complex draws from seven separate sources, all of them simple alkaline water that surfaces clear and clean with no strong sulfur smell. The outdoor pools sit along the stream bank, built from rough stone, and the water flows continuously through them at a natural pace. In the higher pools, the temperature is close to what comes out of the earth. In the lower pools, where river water mixes in slightly, it eases down to something more manageable on a hot afternoon. You choose your pool based on how much heat you can take.
What makes Geto unusual is the cooking arrangement. Several of the inn rooms here come equipped with a small stove and basic provisions, so guests can prepare their own food in the evening. There is no elaborate restaurant service, no kaiseki performance. You eat what you brought or what you cooked, and then you walk outside to the pools in the dark. The stream runs close enough to the outdoor baths that you can hear it clearly from the water, and the beech forest comes right to the edge of the bathing area. In summer, fireflies appear above the stream after ten at night.
The nearest train station is Motoyashiki on the Kitakami Line, about seven kilometers back toward the valley floor. Getting here without a car requires planning, and the limited access hours mean this is not a place you drift into on a whim. That is also why it stays quiet. Geto draws people who specifically want the isolation, the unattended outdoor pools, the simple alkaline water, and the sound of a Tohoku mountain stream with no other noise competing with it.
