Shinjuku is the commuting capital of Tokyo, and contains the busiest train station in the world. To the west, there's an office district with the Tokyo Metropolitan Government Office at its center. To the east, there’s a district with long-established department stores, cinemas and theaters. Shinjuku Gyoen is a park originally built as the garden for the Imperial Household. It is quite famous as a venue for cherry-blossom viewing in March and April. In Shinjuku, many restaurants operate all night, and districts such as Omoide Yokocho (Memory Lane) or Shinjuku Golden Machi have back streets filled with tiny restaurants and bars that reflect each owner’s unique taste and style.
