Kyoto and Osaka
The verdict for August
Peak heat, lantern-lit evenings
+Memorable summer festivals
–Extreme heat and humidity
August is the hottest and most humid month, and Obon brings domestic travellers in mid-month. The Daimonji bonfires light the hills on 16 August. Escape to Kibune or Ohara if the city feels too hot.
Osaka in full summer mode
+Summer fireworks and a genuinely lively festival season.
–The hottest month, typhoon risk building, and Obon (13–16) jams domestic transport.
