Saiko Sightseeing Bus Cancellations

The operator lists six cancelled departures from Kawaguchiko Station: 9:10, 9:40, 10:10, 10:40, 11:10, and 11:40 AM. Service is scheduled to resume with the 12:10 PM departure, but race operations and road conditions may still affect running time.

Later Saiko departures at 12:10, 12:40, and 1:10 PM will detour. During the detour, stops from Fuji-no-Yado Ohashi through Roadside Station Katsuyama cannot be used; the operator directs passengers to Kawaguchiko Herb Hall or Tenjinshita instead.

Kawaguchiko And Local Route Detours

Selected Kofu Line departures from Kofu Station at 7:40, 8:10, 8:50, 9:30, 10:40, and 11:40 AM will detour and will not serve Kawaguchiko Museum of Art-mae. Use Kaitabi-mae instead. The 10:18 AM Tenka Chaya Line departure from Tenka Chaya is included in the same notice.

Kawaguchiko Sightseeing Bus and Oishi-Ashigawa services departing Kawaguchiko Natural Living Center from 9:27 AM through 1:12 PM will not serve the Kawaguchiko Museum of Art stop. Use Music Forest Museum / Hotori-no-Hotel Ban as the alternative.

Plan A Flexible Lake Day

This is a newly published bus-operator notice with exact affected journeys. It adds service details beyond the broader road-restriction information already announced for the triathlon.

If your itinerary depends on one of these stops, travel before the affected window, walk only where a safe public route is available, or move the lake visit to later in the afternoon. Do not enter a closed race section or wait at a stop the operator has marked as unavailable.

Traveler Actions

  • Avoid the six cancelled Saiko Sightseeing Bus departures between 9:10 and 11:40 AM.
  • Use the official replacement stop for any detoured route you plan to take.
  • Allow extra connection time at Kawaguchiko Station and around the north shore.
  • Check live bus operation shortly before boarding because road conditions can add delays.
  • Keep out of race-control areas and follow police, marshal, and bus-staff directions.
