The best time to visit Japan depends on what you want to experience. Spring (March to May) is famous for cherry blossoms, while autumn (September to November) offers colorful foliage. Summer brings lively festivals, and winter is ideal for skiing in Hokkaido or enjoying hot springs.
The easiest way to travel between cities is by Shinkansen (bullet train), which connects most major destinations quickly and comfortably. For longer distances, domestic flights are efficient, while buses are a more budget-friendly option.
