Traveller notes on Matsumoto in May
Matsumoto's forum calls May genuinely changeable — regulars describe a run of three sunny days followed by a day or two of rain, so packing for everything from short sleeves to a rain parka is standard advice. Up at Kamikochi, in the mountains within Matsumoto's borders, early mornings can still flirt with freezing even in May, considerably colder than the city itself; a light down layer for the evening is worth it if you're heading up there.
