Staying in Shinjuku in 2026 is arguably one of the best decisions a first-time or returning visitor to Tokyo can make. Shinjuku Station is the busiest railway station in the world, serving as a massive hub that connects you to almost every part of the city and beyond, including direct lines to Mount Fuji and Hakone. Shinjuku offers a diverse range of districts: the neon-drenched nightlife of Kabukicho, the atmospheric "piss alley" (Omoide Yokocho) for yakitori, and the tranquil Shinjuku Gyoen National Garden for a nature break. While it can be overwhelming due to its scale and constant movement, the convenience of having thousands of restaurants, department stores, and various accommodation tiers at your doorstep makes it the most practical and vibrant home base for exploring the Japanese capital.
