Yokohama Nature Sanctuary, Nature observation park in Yokohama, Japan

Yokohama Shizen Kansatsu no Mori is a nature park in Yokohama with several walking trails that pass through wooded areas and different habitats. The paths wind through sections with native trees, shrubs, and undergrowth where visitors can spot birds, insects, and other animals.

The sanctuary opened in 1986 as the first project of the Environment Agency's nature observation forest programme, launched in 1984 to promote nature conservation education. It was developed with subsidies from Kanagawa Prefecture and the Environment Agency, and volunteer activities support its running.

The park serves as a place where people come to observe plants and animals living in their natural surroundings. School groups regularly walk the trails to learn about the local species that thrive here.

The nature observation center is open 9:00–16:30 and closed on Mondays (the following day if Monday is a holiday) and over the New Year period. To reach the sanctuary, take a Kanachu bus from Kanazawa-Hakkei or Ofuna Station and get off at Yokohama Reien-mae; a hiking trail also connects from Konandai and Kamakura Tenen. There is a paid car park for 100 vehicles.

The sanctuary opened in 1986 as the first project of the Environment Agency's nature observation forest programme, with funding from Kanagawa Prefecture. Volunteers help run it. The adjacent Kamigo Mori no Ie lodging house has a 150-seat hall and a swimwear-required bathing facility called Kenko Bade.
