How cold is Gero Onsen in winter? Temperatures in December, January, and February

According to observation data from Hagiwara, Gero City (about 10km north of the hot spring resort area), the average minimum temperature in January and February is -2.8℃. Even during the day, the maximum temperature is around 5-7℃.

Month	Maximum temperature (average)	Minimum temperature (average)	Clothing guidelines
December	7.9℃	-0.4℃	Thick coat + knit
January	5.1℃	-2.8℃	Down jacket + winter accessories
February	6.6℃	-2.8℃	Down jacket + winter accessories
March	11.2℃	0.3℃	Coat (use the same precautions as in winter for mornings and evenings)

*These are average values ​​from the Japan Meteorological Agency (1991-2020) and are based on observations at the Hagiwara observation point in Gero City. Values ​​may differ slightly in the hot spring resort area.

Once the sun sets, the temperature drops sharply. Keep in mind that the perceived temperature will be significantly different when walking around the hot spring town during the day compared to when watching fireworks and illuminations at night.

Recommended clothing for December, January, and February

December: When the Cold Really Sets In

Daytime temperatures are around 8°C, but they drop to near 0°C at night. Wear a knit sweater or fleece with a thick coat. If you're going out at night, a scarf and gloves would also be a good idea.

January: The coldest time of year

Temperatures are typically below freezing in the mornings and evenings, and it sometimes snows. Layering thermal underwear, a knit sweater, and a down jacket is recommended. Protect your neck, wrists, and ears with a hat, gloves, and a scarf.

February: Just as Cold as January

The minimum temperature is about the same as in January. It gets a little milder during the day towards the end of the month, but you should dress in full winter clothing when going out at night.

Inns and shops are usually well heated in winter. Layering clothes that are easy to put on and take off is more comfortable than wearing just one thick sweater.

Staying Warm at Winter Fireworks and Illuminations

In winter, Gero Onsen hosts a series of evening events. Since you'll be standing still outdoors for extended periods, you'll need to dress even warmer than you would for walking.

- Since your feet will get cold first, wear thick socks and insulated boots.
- Wear thermal underwear (top and bottom) under your down jacket.
- Put disposable hand warmers in your pockets and on your back.
- Your smartphone battery will drain quickly in the cold, so bring a portable battery.

Winter Fireworks at Gero Onsen (December 2026)

The fireworks will be launched at 8:00 PM on December 5th, 12th, and 19th (all Saturdays). There will be a special Christmas performance on December 24th (Thursday). Since you'll be watching from along the river, it will be especially cold on windy days.

Shoes and walking techniques for snowy days

Gero Onsen is a hot spring resort nestled in the mountains, and the town has many slopes and stone steps. On days with snow or ice, these paths become much more slippery than flat roads. Particular caution is needed in the mornings and evenings, as melted snow freezes, making the paths extremely slick.

Go Beyond "Slip-Resistant": Prepare Your Footwear Properly

- Wear snow boots or waterproof boots with deep treads for snowy roads.
- If you wear your regular shoes, it's a good idea to bring anti-slip devices (simple spikes) to attach to them.
- Heels, flat-soled leather shoes, and sneakers are very slippery on slopes.
- Avoid walking outside in the snow wearing traditional Japanese inn clogs or slippers.

How to walk on slopes and snowy roads

- Take smaller steps and land gently on the entire sole of your foot.
- When going downhill, shift your weight slightly forward and walk slowly.
- Do not put your hands in your pockets; keep them free by wearing gloves (so you can put your hands out if you fall).
- Stone steps, bridges, manhole covers, and shaded areas are especially slippery.
- Do not look at your smartphone while walking.

Take Extra Care When Walking to Gassho Village

Gero-Onsen Gassho-mura is located uphill from the hot spring town. It's about a 20-minute walk from Gero Station, but the route involves a continuous uphill climb, and there are also slopes within the village itself.

If you plan to walk there on a snowy or icy day, be sure to wear snow boots and leave with plenty of time to spare. The downhill section on the way back will be more slippery than the way up.

If you're feeling unsure, take the bus (about 6 minutes from Gero Station) or a taxi instead of walking. During the winter illumination period, a free shuttle bus also operates from the hot spring town.

Large suitcases are difficult to pull on snowy roads and slopes, so it's easier to leave them at your inn before exploring.

Precautions unique to hot spring towns: Footbaths and getting chilled after bathing

There are many free footbaths scattered throughout the Gero Onsen town. In winter, be careful as your feet can get cold easily after using them.

• Carry a small towel with you and thoroughly dry your feet before putting on socks.
• Wear shoes that are easy to put on and take off so you can easily enjoy the footbath.
• After soaking in the hot spring, make sure to dry your hair thoroughly before going outside.

If you're walking around the hot spring town in a yukata (traditional Japanese robe) from your inn, be sure to wear a padded jacket called a tanzen over it. Even then, winter nights can be cold, so it's best to stick to short walks.

Things to be aware of when traveling to Gero Onsen in winter

The journey from Nagoya to Gero Onsen takes approximately 1 hour and 30 minutes by JR's "Hida" limited express train. Even on snowy days, you don't have to worry about driving, so the train is ideal for winter travel.

However, from December 25, 2026 to January 5, 2027, all seats on the Limited Express "Hida" will be reserved. Those traveling during the New Year's holiday period should reserve their seats early. Trains may be delayed on days with heavy snow, so please check JR's service information before departing.

If you're going by car, snow tires are essential. The mountain roads leading to Gero Onsen and the slopes in the hot spring town become very slippery with snow and ice. Do not go with normal tires. It's also a good idea to carry tire chains in case of heavy snow.

If you're renting a car, be sure to check if it has snow tires when you make your reservation. If you're not used to driving on snowy roads, taking the train is recommended.
