Soaking in a Slower Pace of Life at Gero Onsen
This is part of Uncovering Japan, a collection of stories that spotlight the lesser known gems that belong on your Japan itinerary, offering everything from a wellspring of local craft and a vibrant street-food culture to traditional wellness. Read more here.
From the perennially roiling waves of Kanagawa's seas to Mount Fuji's snow-capped seat in the sky, some of Japan's most iconic natural sights claim their status through their striking appearances. But peer past those wonders, since immortalized odes and ukiyo-e woodblock prints, to find Gero, a quiet onsen town in Gifu prefecture with the placid, pastoral charm of a Studio Ghibli movie. Though the town may not seem like much upon first look, it's part of a celebrated trinity of hot springs dating back to the 17th-century Edo period, when prominent poet Hayashi Razan first dubbed Kusatsu, Arima, and Gero's hot springs the best in the country. Ever since, generations of locals have sought to experience the legendary waters for themselves.
Tokyo-based chef, sommelier, and writer Yukari Sakamoto has been making the four-and-a-half hour journey to Gero every year since the '80s. Below, she shares why she comes back time after time to soak in the waters, plus her favorite things to do in Gero, and how she makes the most of her time at the onsen town.

Gero, the Goldilocks onsen
Kusatu, Arima, and Gero all possess distinctive charms that make for three unique onsen experiences. Kusatsu sits in a remote region of Gunma prefecture, a little over 100 miles north of Tokyo. 'It's like, once you're there, you're there, you're in the middle of the wilderness,' says Sakamoto.
The town's 13 locally maintained public baths source their water from volcanic origin, particularly from Mount Kusatsu-Shirane. As a result, the springs range from cloudy to clear depending on their acidity and mineral composition, properties which were championed by 19th-century physician to the imperial family Erwin Bälz for their seeming health benefits, ushering in a new wave of popularity for the onsen during the 1800s.
Located about an hour's drive to the southeast of Kusatsu, Arima has a far less demanding transit. The onsen is known for its famous duo of golden (kinsen—named after the sienna hue of the iron-rich water) and silver (ginsen—which is actually colorless) waters and being one of the oldest known onsens in the country with a history tracing back at least 1,300 years. 'The onsen is nice, but it's in quite an urban area, so the surroundings aren't quite as bucolic,' says Sakamoto.
For an onsen that is conveniently located and immersed in natural scenery, Sakamoto finds that Gero strikes the just-right balance. 'What I love about Gero is that you're in the Japanese Alps,' she says. 'You're located inside a valley with mountains on both sides and a river running between them.' From Tokyo, Gero is just two trains away, with the passage after Nagoya being Sakamoto's particular favorite as rolling hills gradually transition into the mountainside and the river runs parallel.
Gero Onsen's public foot bath, right next to the city's main bridge, sees locals stopping daily to soak their feet in the healing waters.
Gero's waters leave an inimitable impression. 'We say in Japanese, tsuru tsuru,' Sakamoto says, 'You sit in the water, and after two or three minutes, you start rubbing your skin, and you feel silky. Even after you've gotten out of the onsen and you're dried up, you still feel that silkiness.' The characteristic custard-smooth feeling the water leaves visitors with is owed to its high alkalinity. Sitting around 9.2 on the pH scale, the water takes on a gently exfoliative, soap-like property.

The joys of taking things slow in Gero
The onsen is a nearly year-round destination, though Sakamoto cautions against visiting in the summertime as it gets a bit too hot to fully immerse in a warm onsen experience. 'Once you get to the city, there are many baths where you can take your shoes off, soak your feet,' Sakamoto says, "and there are always the onsens, the hot springs at the ryokan or the hotel that you're staying at, but there's also a public foot bath that's on the river.' Sitting right next to the city's main bridge, she says its part of the area's everyday life to see somebody stop to soak their feet in the waters.
