The following link takes you to an article in English. I found more details, however, in a video on that page (the screenshots are taken from that video).

  1. 150mm (6 inches) per hour of rain in Kosa, a record
  2. One elderly man in Kosa died when he went to look at river
  3. In Kami Amakusa, a mudslide killed a man in his 90s
  4. Landslides in Uto have trapped two people in their homes
