Typhoons can be predicted by weather forecasts. In the summer, typhoons that form over the ocean south of Japan move north along the edge of a Pacific high pressure system, and move from west to east due to westerly winds. The speed at which they travel are constantly changing due to changes in the typhoon and its path, so it is important to keep up to date with the latest forecast. However, even if the typhoon is far away, it can stimulate fronts near Japan and cause severe weather. Please take proper precaution.

Mountain hut cancellation

When stormy weather due to typhoons is clearly forecasted, it would be reckless to force yourself to climb Mt. Fuji. Postpone your climb to the next opportunity and try again when the weather allows you to climb safely. Please contact the reserved mountain hut to cancel your reservation. The mountain hut will make preparations for guests and if someone is a no-show on the day without contacting them, they worry, ``Something may have happened.'' However, it would be selfish to simply cancel in the event of a light rain. In some cases, cancellation fee may be considered due to personal reasons.
