This is an important public service message for any and all hikers and pilgrims on the Shikoku Pilgrimage at this time. You may not have access to news reports, especially in Japanese, and could possibly be unaware of the typhoon that is steadily approaching Japan at this time.
The size of the typhoon was classified today by Meteorological experts as a “Super Typhoon” or a “Class 5” typhoon. The course of the typhoon is to reach Japan sometime during the weekend, but speed and direction of any typhoon can only be measured in estimates. The centre of the storm may be to the east of Shikoku, but there are very strong cautions regarding dangerous winds that need to be considered.
One of the most dangerous elements of a typhoon is not so much the wind and rain itself, but rather, wind strong enough to move debris. As you may have noticed, many rural houses have clay tiled roofs. These can fall apart and become projectiles in heavy wind and have been known to cause serious injury to people. There is also a danger of falling trees, light posts, and power lines. It may not be safe.
If you are on the Shikoku Pilgrimage I strongly suggest that you make your way via train or bus to the nearest city to you. Takamatsu, Tokushima city, Kochi city, and Matsuyama are the best places for you at this time. In the wake of a disaster there can be a great deal of infrastructure trouble and damage. I would recommend that you take a three day break and enjoy and explore the local restaurants and amenities of Japanese city life until it is safe enough to get back out on the trail.
While it may be true that this giant typhoon may adjust course and have minimum impact on Shikoku, your health and safety are not things to risk. So, please be prudent and smart and stay out of the weather for a few days.
