Overview
Sengokudai Auto Campground is a small, tranquil camping facility tucked deep in the mountains of Kimitsu City in Chiba Prefecture's Boso region. With just 19 tent sites and one bungalow, this campground offers an intimate escape where nature takes center stage — far from the crowds of larger commercial campgrounds.
The site is divided into distinct areas: forest sites nestled among trees and open field sites where vehicles can park directly alongside tents. A standout feature is the availability of tent sail experiences, where elevated tents are suspended between trees, creating a unique floating camping sensation that children and adventurous adults love.
For relaxation after a day of outdoor activities, guests can enjoy the campground's jacuzzi bath set in nature, available for a small fee of 500 yen for adults and 300 yen for children. The combination of mountain air and warm water under the stars creates a memorable experience rarely found at campgrounds of this size.
The location offers remarkable variety in outdoor activities. A clear mountain stream is just a 10-minute walk away, perfect for summer river play and cooling off. Even more surprisingly for a mountain campground, a beach known for its water clarity is only 10 minutes by car, giving families the rare ability to enjoy both mountain and ocean activities in a single trip.
The area around Sengokudai is known for exceptionally dark skies, making it one of the better stargazing locations accessible from the Tokyo area. Seasonal highlights include spring wildflowers, summer insect collecting, autumn foliage around nearby Kameyama Dam, and winter visits to historic Seichoji Temple.
Access from Tokyo takes approximately 2 to 3 hours via the Kisarazu-Higashi Interchange, followed by about 30 kilometers of scenic rural driving. The campground welcomes families, couples, solo campers, and seniors seeking a quiet, nature-immersed experience.
