Shinjuku Gyoen National Garden

Blending French formal, English landscape, and Japanese garden styles, it offers over 1,000 cherry trees for spring hanami picnics. Admission costs just 500 JPY per adult, with children under 15 entering free—an exceptional 2-3 hour family outing. The massive greenhouse displays tropical plants year-round without extra charge, while spacious lawns let younger children play freely. Located 10 minutes from Shinjuku Station South Exit, it’s more accessible than attractions like Sanrio Puroland.
