SECTIONDo not base the departure decision on the weather forecast alone
Combine Japan Meteorological Agency warnings/advisories and snowfall outlooks with road-manager closure information and JARTIC traffic information. Conditions can worsen on an intermediate segment or on the return journey even when the departure area is clear. Do not check only the destination.
| Source | What to check | How to use it |
|---|---|---|
| Japan Meteorological Agency | Warnings for heavy snow, blizzards, snow accretion and snowfall outlook | Identify dangerous periods for departure, activities and return travel |
| Hokkaido road information / JARTIC | Road closures, restrictions, incidents and road cameras | Judge rerouting and whether arrival may become impossible |
| Transport operators | Suspensions, delays and changes to reserved services | Judge whether public-transport participants can still join |
| Facility / venue | Arrival acceptance, parking and use changes | Confirm communication procedures for delay or cancellation |
SECTIONTreat vehicle, driver and passengers as one safety condition
Winter tires do not eliminate poor visibility or icy roads. In addition to vehicle equipment, check driver experience, continuous driving time, substitute drivers, fuel and emergency supplies.
Condition of winter tires and, where needed for the route/vehicle, carrying and fitting chains
Snow brush, gloves, light, charging method, drinks and warm clothing
Fuel level and refueling points
Driver rotation and rest points
A timetable that allows adequate following distance and avoids abrupt driving
SECTIONWork backward from sunset and the tasks after arrival
In winter, getting out of vehicles, unloading baggage and finding the entrance become harder after dark. Work backward not just from arrival time but from when parking, headcount, baggage move-in and facility orientation will be complete. Check sunset time for the specific date using official calendar or forecast information.
SECTIONAgree on criteria for cancellation, postponement or shortening before departure
| Decision factor | Conditions that should trigger consideration of cancellation/change |
|---|---|
| Weather | Potential warning-level conditions, blizzard or expected poor visibility |
| Roads | Closure of a main route, major detour or risk of long immobilization |
| Transport | Cancellation of a reserved service or impossible connection |
| Operations | Unable to secure a safe driver, vehicle or alternative route |
| Facility | Unable to confirm safe arrival, parking or acceptance conditions |
Waiting until everyone has gathered to decide is too late. Decide the decision time, decision-maker, participant communication method and how cost changes will be handled in advance.
SECTIONAdjust training and daily life for winter conditions
If delays are absorbed by cutting sleep or meals, safety the next day can decline. Keep arrival day focused on light confirmation and rest, and prepare layers that are easy to add or remove for temperature differences between outside and indoors. Do not assume wet shoes, gloves or coats can be dried; bring replacements.
SECTIONConfirm winter conditions with BASE NIIKAPPU
The current site notes that snow, icy roads and poor visibility can increase travel time and that parking numbers, vehicle types and positions should be confirmed in advance. Confirm snow-removal coverage, acceptable arrival time, large vehicles, unloading location and delay communication for the actual date of use.
