Nagai Uminote Park Soleil Hill

About this Attraction

Nagai Uminote Park Soleil Hill in Yokosuka, Kanagawa, is a vibrant, family-friendly park that offers something special in every season. Set against a stunning coastal backdrop overlooking Sagami Bay, this expansive hillside park is famous for its colorful flower fields, interactive attractions, and wide-open spaces, making it a perfect destination for both relaxing strolls and outdoor adventures.

One of the biggest draws is the park’s seasonal flower displays. In winter, fields of bright yellow nanohana (canola flowers) blanket the hills. In spring, the landscape transforms with sky-blue nemophila (baby blue eyes) and cheerful poppies. Summer brings tall, golden sunflowers, while autumn dazzles with swaying pink and purple cosmos—offering year-round beauty for photographers, couples, and families alike.

The park also features a variety of recreational activities. Families can enjoy the Flower Train, petting zoo, BBQ areas, and even a giant Ferris wheel. Children love the adventure playground and go-karts, while adults appreciate the peaceful walking trails and relaxing onsen-style foot bath. There’s also a farm shop selling fresh local produce and unique souvenirs.

Entry to the park is free, though some activities like the train or go-karts require a small fee. With amenities like cafes, restrooms, bike parking, and pet-friendly zones, it’s easy to spend 2–3 hours or even a full day enjoying everything the park has to offer.

Easily accessible from Yokosuka or even central Tokyo as a day trip, Nagai Uminote Park Soleil Hill is a scenic, all-season escape where nature, fun, and family experiences come together on the coast of Kanagawa.
