What to Wear in Tokyo in December
Tokyo in December: 12°C / 54°F afternoons, 4°C / 39°F nights, about 5 wet days and 174.4 hours of sun, with dark at half past four.
- Beige wool overcoat, knee length — 3.8°C / 39°F at dawn and 12°C / 54°F in the sun by two
- Rust lambswool crew — the whole outfit once the coat comes off indoors
- Cream cotton button-down — enough under the open coat on the brightest afternoons
- Deep brown wool-flannel trousers — the minimum drops below freezing on 1.6 mornings
- Plaid wrap midi skirt with dark tights — for the Marunouchi Illumination, lit from 12 November
- Black penny loafers — 5.2 wet days, and shoes come off at restaurant doors
- A rain shell — 57.9mm across the month; a ¥700 conbini umbrella covers the odd wet afternoon
- Snow boots — snow falls on 0.6 days in an average December
- A down puffer — too warm for a 12°C / 54°F walk in full sun
- Evening plans that assume daylight — the sun sets at about 4:30pm all month
Pack for cold sun. The Japan Meteorological Agency (JMA) gives Tokyo's December 57.9mm of rain on 5.2 wet days and 174.4 hours of sunshine, which on the same station's figures makes it drier and brighter than November. The catch is the range. Afternoons reach 12°C / 54°F, dawn falls to 3.8°C, and the sun sets at about 4:30pm from the first of the month to the last. So the capsule is wool, with no rain gear in it: a beige overcoat you can open at noon, a rust knit under it, flannel by day and a plaid skirt with tights for the evening. From 12 November the Marunouchi Illumination lights about 1.2km of Naka-dori's street trees in champagne gold, and that walk starts after dark.
Tokyo's December asks for wool, not waterproofs. The rain has gone, the sun shines for 174 hours, and the dark comes at half past four.
The capsule
01Beige single-breasted wool overcoat, notch lapel, knee lengthStart with the coat, because the day runs from 3.8°C on the first train to 12°C / 54°F by two. A knee-length beige wool overcoat, single-breasted with a notch lapel, buttons for the morning platform and hangs open in full sun at noon. Beige holds the rust knit and the brown plaid together, and it stays light against a dark street after half past four.
02Rust lambswool crew-neck sweaterTwelve degrees in full sun is a knit day, not a coat day. A rust lambswool crew carries a 12°C / 54°F afternoon with the overcoat hanging open, and it becomes the whole outfit once the coat is on a hook at lunch. Rust is the one strong colour in the capsule, chosen to sit between the beige coat and the oxblood bag.
03Cream cotton button-down, chest pocketWear it under the rust crew in the morning and alone under the open coat on the brightest afternoons. JMA counts 21.7 December days that get at least 40% of their possible sunshine, and on those a cotton shirt under wool is enough by two. Cream rather than white, so it meets beige wool without a hard line, and the chest pocket takes an IC card.
04Deep brown wool-flannel straight trousersOn 1.6 mornings in an average December the minimum drops below freezing, and denim lets that cold straight through. Deep brown wool flannel holds warmth from the 7am platform to a late lunch, and a straight leg sits cleanly over a penny loafer. Brown also picks up the darker stripe in the plaid skirt, so both bottoms share one coat and one bag.
05Beige-and-brown plaid wrap midi skirt, tie at the hipSave it for the illuminations. A beige-and-brown plaid wrap skirt tied at the hip, with sheer dark tights and loafers, is the evening outfit for walking about 1.2km of lit street trees on Marunouchi Naka-dori. The wrap adjusts over a knit, and a midi hem keeps the cold off your knees once the sun has gone at half past four.
06Black leather penny loafersDecember is dry enough for smooth leather: 5.2 wet days, and only 1.8 of them bring 10mm or more. Black penny loafers slip off at a restaurant door or a temple hall and go back on without a shoehorn, and they work with both the flannel trousers and the tights. Snow falls on 0.6 days in an average month, so a boot buys you nothing here.
07Oxblood structured leather shoulder bag, gold claspOne bag for the day and the lights. An oxblood structured shoulder bag with a gold clasp keeps its shape with the ivory scarf folded inside at noon, sits close under the coat on the walk down Naka-dori, and the clasp picks up the champagne-gold trees after dark. Oxblood is the deepest colour in the capsule, and it anchors all that beige.
08Ivory lightweight cotton scarf, fringedCotton, not wool, because the cold sits at the two ends of the day and the middle is 12°C / 54°F in sun. A light ivory scarf with a fringed edge closes the open collar of the coat on the 8am train and folds into the bag by lunch. For the midnight bell at Zōjō-ji on 31 December, wind it twice and button the coat.
Day to night
Beige overcoat buttoned · cream button-down under the rust crew · deep brown flannel trousers · black penny loafers · oxblood bag · ivory scarf. Out at eight near 4°C / 39°F, the Issey Miyake stores in Minamiaoyama at eleven, the coat open in the sun by one.
Rust crew · plaid wrap skirt tied at the hip · sheer dark tights · black penny loafers · overcoat open · ivory scarf loose · oxblood bag. Dark by half past four; walk the lit length of Marunouchi Naka-dori under the trees, then dinner in Marunouchi.
A suggested look — beige wool overcoat, rust crew-neck sweater, beige and brown plaid wrap midi skirt, black penny loafers, black sheer tights.
What to avoid
- A rain shell — 57.9mm on 5.2 wet days; buy a conbini umbrella on the day it rains
- Snow boots or lug soles — snow on 0.6 days, and shoes come off at the door
- A down puffer — too warm for a 12°C / 54°F walk in full sun
- Photo plans for five o'clock — the sun sets at about 4:30pm all month
- Just a knit at Zōjō-ji on New Year's Eve — the bell rings at midnight, hours after dark
Frequently asked questions
Cold, dry and bright. The Japan Meteorological Agency's 30-year averages for the Tokyo station give December a mean daily maximum of 12.0°C / 54°F and a mean minimum of 3.8°C / 39°F, with a monthly mean of 7.7°C. Rain totals 57.9mm on 5.2 days of 1mm or more, and sunshine adds up to 174.4 hours, against 149.8 in November. The minimum drops below freezing on 1.6 days, snow falls on 0.6, and average humidity is 56%. Daylight runs about 9h 55m on 1 December and 9h 45m from mid-month, with sunset near 4:30pm.
A knee-length beige wool overcoat, a rust lambswool crew, a cream cotton button-down, deep brown wool-flannel trousers, a beige-and-brown plaid wrap midi skirt with sheer dark tights, black leather penny loafers, an oxblood structured shoulder bag and a light ivory scarf. That covers a morning near 4°C / 39°F, a sunny 12°C / 54°F afternoon and an evening under the Marunouchi lights. Leave the rain shell, the snow boots and the down puffer at home. December has 5.2 wet days and snow on 0.6, and a conbini umbrella handles the rest.
The Marunouchi Illumination, in its 25th edition, runs from 12 November 2026 to 14 February 2027. Marunouchi.com describes "シャンパンゴールド色の光" (champagne-gold light) across about 1.2km of street trees on Marunouchi Naka-dori. MARUNOUCHI BRIGHT HOLIDAY, a Harry Potter theme with a symbol tree at the Marunouchi Building, runs alongside it from 12 November to 25 December, some elements excepted. Lighting hours were still unpublished in late September, with details promised for late October. Dress to walk the whole street after a 4:30pm sunset: wool coat, knit, closed shoes.
Early December for the lights, the last week for the New Year. The Marunouchi Illumination is lit from 12 November and Bright Holiday runs to 25 December, and Zōjō-ji in Shiba traditionally opens sales of its bell-ringing tickets on 1 December. Late December brings the solstice on 22 December and Joya no Kane: Zōjō-ji's events page describes "深夜0時108の煩悩を取り除く「除夜の鐘」", the midnight bell that clears the 108 worldly desires. Tokyo's holiday ordinance closes metropolitan government offices from 29 December to 3 January, so check a public venue's hours before planning that week around it.
December is colder, drier and brighter. JMA's figures for the Tokyo station give November 16.7°C by day and 8.8°C at night, against December's 12.0°C and 3.8°C, so both ends drop about five degrees. Rain falls from 96.3mm on 7.4 wet days to 57.9mm on 5.2, and sunshine rises from 149.8 hours to 174.4. Our November guide, built on NOAA's record, dresses the koyo weeks in a slim charcoal coat and a camel knit. December swaps them for a beige wool overcoat, a rust crew and tights, and leaves every piece of rain gear behind.
A wool overcoat over a knit, straight trousers or a midi skirt with tights, and leather shoes that slip off. BEAMS is the local reference: it opened as American Life Shop BEAMS in Harajuku in 1976 and added BEAMS F for traditional menswear in 1978. Issey Miyake, whose design studio dates from April 1970 and whose stores sit in Minamiaoyama, covers the pleated end with PLEATS PLEASE, launched in February 1994. For the bag, Yoshida & Co., founded in Kanda Sudachō in 1935, launched PORTER in 1962 and opened PORTER MARUNOUCHI, its second own store, in 2002.
