Around Shinjuku
Neon chaos, tiny bars, and a surprisingly serene garden
Shinjuku is the Tokyo people picture before they arrive, and it's every bit that intense. The trick is knowing when to switch modes. Golden Gai and Omoide Yokocho are for tiny-bar nights, and Shinjuku Gyoen is for when you need the volume turned down. The entry fee at Gyoen keeps the crowds manageable even in cherry blossom season, which makes it one of the best value tickets in the city.
Shinjuku has 16 places on the Roam Tokyo map: 4 restaurants, 4 bars, 2 parks and gardens, 2 bathhouses, 1 shrine or temple, 1 viewpoint, 1 landmark and 1 neighbourhood. Read the Shinjuku guide.
