The month the whole country slows down
January opens with Shogatsu, Japan's most important holiday, when temples are hushed and families gather at home. After the first week the streets empty out and the season belongs to snow country: onsen towns dusted in white, monkeys warming in Nagano's hot springs, and Hokkaido slowly stacking up the powder that explodes into festival season in February.
Why January Is Special
Onsen season at its peak
January is the true start of onsen season, and it transforms Japan's hot-spring towns into something out of a film. Ginzan Onsen in Yamagata is the postcard: a preserved Taisho-era village where steam rises off the river and guesthouses glow lantern-lit under fresh snow. Nearby Zao Onsen adds its famous "snow monsters" — trees encased in ice that catch the light at sunrise. The trick is timing: onsen towns are at their quietest midweek after January 4, when the New Year crowds go home.
The skiing and the slow lane
Powder season peaks this month. Niseko regularly sees 10-15 meters of annual snowfall, and runs are emptier than February's festival weeks; Hakuba and Shiga Kogen are the Honshu alternatives with better access from Tokyo. If you'd rather skip the snow, January is one of the quietest months at Tokyo's major sights — Senso-ji and Meiji Jingu have genuine breathing room except for the January 1-3 hatsumode rush, when temples like Meiji Jingu draw over three million visitors in a single day.
Photo opportunities
- Snow-covered torii gates and shrines at first light.
- Onsen steam against morning frost — best at 6-7 AM with a telephoto.
- Lantern-lit snow streets in Ginzan and Otaru after dusk.
Local tips
- New Year week (Dec 28-Jan 3) closes shops and restaurants nationwide — stock up before then.
- Pack an extra layer: Japanese indoor heating is weak, and ryokan rooms can sit near 18°C.
- Ski rentals are cheapest bought in Japan rather than abroad; Niseko gear runs about ¥5,000-8,000/day.
What's On in January
- Hatsumode shrine visits (Jan 1-3) for Japan's New Year tradition
- Coming-of-Age Day ceremonies in every city (2nd Monday of January)
- Winter illuminations still glowing in Tokyo, Osaka & Nagoya
- Ski season in full swing at Niseko, Hakuba & Shiga Kogen
The Short Answer
In January, Japan’s temperatures average 1°C to 10°C, with about 6 rainy days and a crowd level of 3/5. It’s best for onsen soaks, snow-country scenery and winter illuminations in Hokkaido.

Where to Base Yourself in January
Base yourself in Tokyo or Nagano
Tokyo keeps the biggest choice of shops, food and illuminations, and day trips to snow country are easy. Nagano is the smarter pick if skiing, snow monkeys and onsen are the real goal — Hakuba, Nozawa Onsen and Jigokudani are all within an hour.
Best January Day Trips
- Jigokudani Snow Monkey Park, Nagano — wild macaques bathing in steaming pools
- Ginzan Onsen, Yamagata — a preserved Taisho-era hot spring village under snow
- Kawagoe, Saitama — 'Little Edo' lantern-lit streets and cozy winter cafés
Money in January
January is a quiet-value month after the New Year rush clears: hotel prices drop sharply from Jan 4, and only New Year week itself is expensive. Flights booked before mid-December are the cheapest of the winter.
Local Tip
Japan's indoor heating is weak by Western standards — pack an extra layer for evenings, and always carry warm socks. A portable hand warmer (kairopo) is a cheap game-changer in January.
