Koishikawa Botanical Garden

Koishikawa Botanical Garden is one of Tokyo's oldest and most historically significant green spaces, operated by the University of Tokyo and tracing its roots to a medicinal herb garden established in the 17th century. The garden's ancient trees — some centuries old — create a forest atmosphere remarkably unlike the manicured parks found elsewhere in the city, with winding paths that feel genuinely exploratory.

For families with curious children, this is an educational and atmospheric outdoor experience. Kids who love nature will respond to the scale and age of the trees, the seasonal flowers, and the sense that the garden has been here for generations. The terrain is varied with hills, slopes, and unpaved paths, which makes it a more active walking experience than flat botanical gardens — but also means it is not ideal for strollers.

A baby carrier works much better for younger children.

Admission is modest — around USD 4-5 per adult with children under 15 entering free. Spring cherry blossom season is particularly rewarding here since the garden's blossoms are spectacular and far less crowded than Ueno Park just a short distance away. There are no food vendors inside, so pack snacks. The garden is closed on Mondays and between late December and early January.
