Destination de Voyage calculation based on these normals: May is 4 to 6 °C (7 to 11 °F) warmer than April in every city in the table (Tokyo +4.2 °C / 7.6 °F, Kyoto +5 °C / 9 °F, Sapporo +6.2 °C / 11.2 °F). It is also the sunniest month of the season in Hiroshima (211 hours) and Fukuoka (204 hours). Rainfall rises only slightly on Honshu (Tokyo: 134 → 140 mm / 5.3 → 5.5 in), but jumps in Naha (161 → 245 mm / 6.3 → 9.6 in). June then brings much less sunshine to Tokyo (124 hours versus 180 in May). These normals match those on our page best time to visit Japan.
When does the rainy season start?

| Northern Kyushu (Fukuoka) | around 4 June | around 4 June |
| Kinki (Kyoto, Osaka) | around 6 June | around 4 June |

Typhoon season in Japan runs from June to December, peaking from July to September (UK FCDO, GOV.UK, updated 28 August 2026): keep an eye on the forecasts during your stay.
