The transport ministry has found that the operator of the chartered ski-tour bus that crashed in Nagano Prefecture late last week was running the tour without providing its drivers with the required instruction paperwork, officials said Monday.
Conducting the tour without the paperwork required by the ministry is a violation of the Road Transportation Law.
Tokyo-based ESP provided its drivers with an instruction paper together with a basic itinerary given by Keyth Tour, the travel company that organized the tour.
