Local government authorities have not found any solution to prevent accidents similar to the one that took place a week ago when 18 campers on the Kurokura River were swept away in the town of Yamakita, Kanagawa Prefecture.

Tetsuro Ito, chief of Kanagawa Prefecture's River and Port Division, said the prefecture has no guidelines for instructing campers who refuse to respond to flood or other warnings.

Since the accident, the prefecture has launched a discussion on camping, responding to calls that local authorities should introduce ways to regulate camping at rivers.
