Yes, you can walk around the grounds of Sensoji Temple in Asakusa, Tokyo, at night, and it is highly recommended for a more peaceful experience. While the Main Hall (Hondo) and the amulet shops typically close around 5:00 PM, the temple grounds themselves remain open to the public 24 hours a day. Every evening from sunset until 11:00 PM, the temple's iconic structures—including the Kaminarimon Gate, the Hozomon Gate, and the stunning five-story pagoda—are beautifully illuminated. Visiting at night allows you to appreciate the intricate architecture without the overwhelming daytime crowds, offering a serene atmosphere that is perfect for photography. The nearby Nakamise-dori shopping street also takes on a different charm after the shutters come down, as many of the storefronts feature hand-painted murals depicting local history and seasonal festivals, which are only visible when the shops are closed.
