The biggest surprise for visiting families is how much Japan changes around New Year. Christmas isn’t a public holiday here, so December 25 is a normal working day. The real slowdown comes from December 29 to January 3: government offices close by law, banks close December 31 to January 3, and many museums take a few days off. Shops, restaurants and attractions set their own hours, and much of the country travels home.

I live in Tokyo with my daughter. This guide covers what December in Japan is actually like with kids: the weather, the lights, what’s closed when, and how to plan around the New Year rush.

Ramen Dad’s note: My daughter and I have our own December traditions in Tokyo. It’s a good month to visit, as long as you plan around New Year.

Quick answer: Japan in December with kids

Weather figures are the Japan Meteorological Agency’s 1991–2020 averages for Tokyo.

December weather in Japan

December in Tokyo is cold but bright. Here are the official averages for four cities families often visit:

(Japan Meteorological Agency, Japanese). “Snow days” are days when any snow falls, even a few flakes, not days with snow on the ground.

What that means with kids:

• In Tokyo and Osaka you’ll need a warm coat, but snow boots are rarely necessary. Midday in the sun can feel mild; evenings at an outdoor illumination feel cold fast.
• Kyoto is a little colder and has more snow days than Tokyo: 6.9 on average. Most are light flurries, though: the average total snowfall for the month is only 2 cm, so don’t expect snowy temples.
• Sapporo is real winter: below freezing on average, with snow falling on most days. In an average December, 113 cm of snow falls in total. Pack waterproof boots with good grip, gloves and a hat for everyone.
• Sunset is early. In Tokyo the sun sets at 4:28 p.m. on December 1 and 4:37 p.m. on December 31 (National Astronomical Observatory of Japan, Japanese). Plan outdoor sightseeing in the morning and save the lights for after an early dinner.

What to pack for Tokyo in December

1. A warm coat and layers. Trains, shops and restaurants are heated, so kids get hot inside and cold outside. Layers you can take off beat one thick sweater.
2. Hats and gloves for evening light shows.
3. Lip balm and moisturizer. Tokyo’s December humidity averages 56%, much drier than summer’s 70%-plus.
4. Comfortable shoes that handle a long walk; snow boots only if you’re heading to Hokkaido or the mountains.
5. A small blanket or footmuff for a stroller at night.

If you’d rather not carry winter coats for the whole family between cities, luggage forwarding lets you send big bags ahead.

Ramen Dad’s note: I dress my daughter for Tokyo’s December weather. Pack layers, plus hats and gloves for evening lights.

Christmas lights and December events

Tokyo lights up with winter illuminations: festive light displays all over the city. Many are free and outdoors, which makes them easy with kids: go after dinner, walk for 30 minutes, head back.

Tokyo Disney’s Christmas

Tokyo Disneyland and Tokyo DisneySea run Disney Christmas from November 11 to December 25, 2026. At Disneyland that means the “Toys’ Wonderous Christmas!” parade, a Christmas version of the Electrical Parade Dreamlights, and the “Starbright Christmas” fireworks. The Disney hotels add decorations from November 11. (Oriental Land press release, Japanese)

Tickets are priced by date. In late 2026, most December weekdays are ¥10,900 (≈$69) per adult, December 25–26 are ¥12,400 (≈$78), and New Year week is ¥11,900 (≈$75). Children 3 and under are free. Tickets go on sale every day at 2:00 p.m. Japan time for the same date two months later, so December 25 tickets go on sale on October 25 (Tokyo Disney Resort). If you buy through a third-party seller, compare the date and cancellation conditions first. My Tokyo Disney with a toddler guide explains the prices, Premier Access and Rider Switch.

The amusement park Yomiuriland, in western Tokyo, lights up for its Jewellumination season from October 29, 2026. You can ride attractions under the lights, and there are fountain shows. Check the official site (Japanese) for hours and tickets.

Tokyo Dome City

Last winter, Tokyo Dome City’s free illumination ran from November 17, 2025 to March 1, 2026, 5 p.m. to midnight, with about a million LEDs. The 2026–27 dates hadn’t been announced when I checked; GO TOKYO lists it each year. It pairs well with the ASOBono! indoor playground on the same site, in my guide to indoor playgrounds in Tokyo.

Other big illuminations, such as the street lights in Marunouchi and Roppongi, usually announce their dates in October or November. Search the name plus “2026” on the official site before you go.

Ramen Dad’s note: We’ve gone to see Tokyo’s winter lights with my daughter. Check the official dates before you go, since many illuminations announce them late.

New Year closures: what shuts and when

This is the part to plan around. Japan’s New Year (shōgatsu) is a family holiday, and the closures follow rules:

Tokyo National Museum closes earlier than the table suggests. It’s closed on December 15, 2026 for maintenance, and from December 22 to 25 only the Horyuji Treasures Gallery and Kuroda Memorial Hall are open. The Asian Gallery (Toyokan) is closed from November 30 to December 31 (TNM). If the main galleries matter to you, go before December 22.

In 2026–27, December 31 is a Thursday, so January 2 and 3 fall on a weekend.

A few practical points:

• Cash: bank branches close December 31 to January 3, and don’t count on an exchange counter. Convenience-store ATMs are the backup: Seven Bank ATMs (in 7-Eleven stores) run 365 days a year and take many overseas cards (Seven Bank). Still carry some yen for small shops and shrines.
• Museums: the ones I checked close for a few days between December 26 and January 1, and the exact days differ, so check each one.
• Theme parks such as Tokyo Disney stay open, and get busy.
• Shops and restaurants set their own New Year hours, so check before you go, especially for January 1.
• If a child gets sick over New Year, regular clinics are closed. In an emergency, call 119 for an ambulance; Tokyo arranges interpretation in English (Tokyo Metropolitan Government). Visitors aren’t covered by Japan’s public health insurance, so bring travel insurance. My guide to what to do if your kid gets sick in Japan covers holiday clinics and Tokyo’s #7119 advice line.

Ramen Dad’s note: Living here, I’ve learned how the New Year shutdown works. Check each place’s hours for January 1 rather than assuming.

New Year customs your kids can join

New Year is one of Japan’s most important holidays, with traditions families can join.

• Toshikoshi soba (年越しそば): buckwheat noodles eaten on New Year’s Eve.
• Joya no kane (除夜の鐘): temple bells rung at midnight on New Year’s Eve.
• Hatsumōde (初詣): the first shrine visit of the year. Meiji Jingu, next to Harajuku Station, draws several million visitors between December 31 and January 3, and stays open all night on December 31 (GO TOKYO, Japanese). With small kids, I’d skip midnight and go on a weekday morning later in the first week, when it’s calmer. At big shrines expect long lines, packed paths and little room for a stroller; a quiet neighborhood shrine can be a better first visit.
• Omikuji (おみくじ): paper fortunes you draw at shrines. Kids enjoy reading them.
• Kadomatsu and shimekazari: pine-and-bamboo decorations and straw ropes at doorways, a good thing to spot on a walk.

Ramen Dad’s note: We go for hatsumōde with my daughter. Big shrines like Meiji Jingu draw huge crowds from December 31 to January 3.

Crowds and transport around New Year

• Shinkansen: the year-end and New Year are peak season. On the Tokaido Shinkansen, smartEX reserved fares rise by ¥200–¥400 per adult in peak seasons, and the EX Family Hayatoku 7 family discount isn’t available from December 25, 2026 to January 5, 2027 (smartEX, Japanese). smartEX takes requests up to a year ahead and confirms seats one month before the travel date (smartEX). Book early so the family can sit together.
• Airports are busy at the same time. My Narita and Haneda arrival guide lists last trains and buses if your flight lands late.

A family plan for December

Early to mid-December (my pick): lights are up, museums are open, prices are lower. Do sightseeing in the morning and illuminations after an early dinner.

Christmas week: Disney’s Christmas event ends December 25, and December 25–26 are among the most expensive Disney days. Book tickets as soon as they go on sale.

December 28 to January 3: plan around New Year traditions, theme parks and outdoor walks rather than assuming museums are open. Check every museum date first.

An easy December day in Tokyo with kids:

• Morning: parks or outdoor sights while it’s sunny.
• Midday: lunch somewhere warm.
• Early afternoon: an indoor museum or a rest at the hotel.
• From about 4:30 p.m.: it’s dark, so head to the lights. Each illumination sets its own hours.
• Dinner, then back before everyone gets too tired.

FAQ from parents

“Is Christmas a big deal in Japan?” It’s a festive season with lights and Christmas events, but not a public holiday: there are no national holidays in December, so offices run as normal on December 25.

“Will everything be closed on New Year’s Day?” Not everything. Government offices and banks close by law, and many museums close for a few days. Shrines and theme parks like Tokyo Disney stay open.

“Will we see snow in Tokyo?” Probably not. An average Tokyo December has 0.6 snow days. For snow, head to Hokkaido or the mountains.

“Is December good for Tokyo Disney with kids?” The Christmas parade and fireworks are a highlight, and early-December weekdays are cheaper than Christmas week. Dress the kids warmly for the evening.

Before you go: December checklist

1. Check museum dates from about December 22 to January 4.
2. Carry some cash and know where the nearest convenience-store ATM is.
3. Book Shinkansen seats early if you’re traveling around New Year.
4. Buy Disney tickets the day they go on sale: October 25 at 2 p.m. Japan time for Christmas Day.
5. Pack layers, hats and gloves for evening lights.
6. Plan sightseeing before 4 p.m.; it’s dark by about 4:30.
7. Save 119 and #7119 and the holiday clinic info.

Ramen Dad’s note: My one piece of advice: plan sightseeing before 4 p.m., since it’s dark by about 4:30. The lights are worth staying out for after that.

Weather figures are the Japan Meteorological Agency’s 1991–2020 averages. Dates, prices and closures were checked against official websites on October 9, 2026. Many venues publish their 2026–27 year-end schedules in November or December, so check again closer to your trip.
