Shikoku in January

Spring and fall own Shikoku's calendar. Cherry blossoms peak in early April, when temple grounds explode in pink and hiking trails become outdoor galleries. But crowds follow flowers, so consider late March when buds are swelling but tour buses haven't arrived. Fall colors start in the mountains during October, then cascade toward the coast through November. This is prime pilgrimage season when walking 1,400 kilometers actually sounds appealing. Summer brings festivals—Awa Odori in Tokushima during mid-August turns the entire city into a dance party. But temperatures hit 35°C and humidity makes every step feel like swimming through soup. Winter stays mild along the coast but mountain temples can see snow. The upside? You'll have ancient halls to yourself, and hot springs feel like salvation instead of luxury. Avoid Golden Week in early May unless you enjoy sharing temple steps with half of Tokyo.
