I like to talk about Rainy season in Japan.
In Japan, the rainy season lasts from early June to mid-July for most of the country (on the main island of Honshū and the islands of Kyūshū and Shikoku), approximately June 7 to July 20 for the main Kansai and Kantō regions.
Kids does not like rainy days & They make TERU-TERU-BOUZU(small doll for stop rain)
Enjoy your Japan trip!!
