What kind of belongings should I bring?

The weather on the island is changeable, and solid preparation is required.
Rain preparation is especially important, as the annual precipitation on the island is about twice as much as in the interior.
Wind is often so strong that umbrellas are useless, so rainwear is recommended.
In addition, most of the island is covered with mountain forests, and the surface temperature drops in the morning and evening. In addition, since the actual temperature often feels cooler than the forecasted temperature, a light jacket or windbreaker is useful as a countermeasure against the cold.
