About Japan
Japan blends ultra-modern city energy with timeless tradition, making it one of the most rewarding places to explore. In Tokyo, neon neighborhoods, world-class food, and cutting-edge culture sit alongside serene shrines and quiet gardens. Kyoto and Nara offer classic Japan—temples, bamboo groves, geisha districts, and centuries-old streets—while Osaka brings a laid-back vibe and legendary street food. Beyond the cities, Japan opens up into dramatic landscapes: Mount Fuji views, alpine villages, coastal islands, and forested national parks. Travelers can unwind in natural hot springs (onsen), ride the shinkansen to cover huge distances fast, and plan around the seasons—cherry blossoms in spring, festivals in summer, fiery autumn leaves, and powder snow in winter.
