March in Japan marks a gentle shift from winter to spring. The air softens, though a light chill lingers, and the landscape begins to glow with deep pink plum blossoms and the first early-blooming cherry blossoms, such as Kawazu-zakura, in warmer areas.

This is also when the main cherry blossom season begins to unfold. In Tokyo, blooms typically open around March 18, followed by Kyoto around March 22 and Osaka around March 23, with full bloom arriving roughly a week later in each city.

It is the season of “Sanko-Chon,” when three colder days are followed by four milder ones, creating ever-changing conditions. In the north, ski season winds down, while in cities like Tokyo, Kyoto, and Osaka, terrace dining and garden strolls begin to feel inviting again.

Seasonal flavors turn fresh and slightly bitter, with bamboo shoots, sweet strawberries, and sakura-inspired treats appearing in shops and restaurants. As the school year wraps up in late March, a celebratory buzz fills the air, making it an especially lively time.

Tokyo will have a fairly mixed week, with lots of clouds, a few light showers, and a brief spell of sunshine early on. Daytime temperatures will gradually rise from the low teens to the high teens, while mornings and evenings stay cool at around 9 to 11°C. Since rain could pop up on and off, it is a good idea to keep plans flexible if you will be out exploring.

Sapporo starts the week with a bit of rain, then shifts into a more pleasant mix of sun and clouds. Midweek looks brighter, but cloudier skies return as the weekend gets closer. Highs will stay fairly steady at around 8 to 12°C, while nighttime temperatures will feel much colder and may drop to around freezing before easing back up.

Sendai begins the week with clear, bright weather before cloudier skies take over. The first half of the week looks mostly dry, but light rain becomes more likely toward the weekend. Highs will range from about 12 to 16°C, while mornings stay chilly, especially early in the week.

Osaka will see a mostly cloudy week with a little sunshine mixed in from time to time. Rain chances come and go, with wetter periods more likely around midweek and again near the weekend. Temperatures will stay quite comfortable overall, with highs around 15 to 19°C and lows around 8 to 11°C.

Fukuoka starts the week on a bright note, but conditions turn cloudier and more unsettled as the days go on. Highs will mostly stay around 18 to 19°C, although there may be a cooler dip in the middle of the week when temperatures struggle to get much above 14°C. Early mornings will still feel crisp, with lows around 9 to 11°C.

Naha will have a mostly cloudy week with a few brighter breaks. The first part of the week looks a little damp, followed by a pattern of clouds and occasional light rain. It should stay pleasantly warm overall, with the kind of mild days and comfortable evenings typical of Okinawa at this time of year. Rain is not likely to last all day, but brief showers will be possible on and off.
