Japan was attacked by the huge typhoon called Hagivis (we call it Typhoon No.19) last Saturday. It was probably the biggest in the last 30 years or so. At least, I cannot remember past typhoons had affected Kanto area this much.
Hakone area was affected much, too. The volume of the rain was the record heavy in the area. People said that roads were like rivers.
It is reported that some of roads in the area are still closed. I checked roads by myself and confirmed some roads are actually closed.
