Kumamoto in January The fewest wet days of the year. Walking in town at midday is fine, but it gets cold fast after sunset. Highland areas such as Aso run much colder than the city, so pack warmer if you plan to go.
January in Kumamoto was brisk: 11°C by day, 1°C at night. Standing in the shade felt chilly. With about 5 rain days, showers were an occasional nuisance rather than the rule. Across 20 years the count stayed between 2 and 8, with little spread.
10 nights a month dropped below freezing on average. Gloves earned their place for early starts. Not every year was typical: 2020 ran 2.3°C warmer than the mean, with highs of 13.2°C. The lowest night on record was −8.6°C in 2016.
