The recommendations were received by residents of the prefectures of Kagoshima, Ehime and Kumamoto, the NHK broadcaster reported. The heavy rainfall has reportedly increased the risk of landslides in the affected areas.
According to newspaper The Japan Times, one woman has already died in Kagoshima after a landslide on a mountain behind her house buried the building in mud.
The situation is not going to improve within next the 24 hours as the heavy rainfall will continue on the southern Japanese islands of Kyushu and Shikoku.
