Watch out for heavy rain in the first half
Heavy rain can occur toward the end of the rainy season. Hiroshima's July precipitation is 279.8mm, the most of any month, so check the weather forecast often.
Guard against heatstroke after the rainy season ends
Avoid spending long periods outdoors during the day, and take in water and salt frequently. Be especially careful in places with little shade, like the Tottori Sand Dunes and the Shimanami Kaido.
