Free Campgrounds with Hot Springs Near Tokyo

The two best things about camping in Japan — free campsites and hot springs — are rarely found together in the same facility. But they do not need to be. The best budget strategy is to camp for free near a public bathhouse, spending ¥0 on accommodation and ¥500-1,000 on the best bath of your life.

Why free camping + onsen is the move

A glamping site with a private onsen runs ¥15,000-40,000 per night. A free riverside campsite plus a walk to a ¥700 day-use bathhouse gives you the same core experience — sleeping outdoors and soaking in hot mineral water — for under ¥1,000 total. The tent is less luxurious, but the water is the same.

This approach works because Japan has an incredible density of public bathhouses. Nearly every mountain town and river valley has at least one day-use onsen (日帰り温泉), and many are within walking or short driving distance of campable areas.

How the setup works

1. Find a free or cheap campground — riverside spots, municipal sites, or budget campgrounds under ¥1,000
2. Locate the nearest day-use onsen — search Google Maps for 日帰り温泉 (higaeri onsen) near your campsite
3. Time your soak — most day-use onsen are open until 8-9 PM. Go after setting up camp and before dinner for the best experience
4. Bring your own towel — rental towels cost ¥200-300. Save money by packing a quick-dry camp towel

Tanzawa: riverside camping + day-use onsen

The Tanzawa mountain area in Kanagawa is the best free-camping-plus-onsen combination near Tokyo. Free riverside camping along the Nakatsugawa River puts you within striking distance of several bathhouses.

• Tsurumaki Onsen (鶴巻温泉) — A small onsen town on the Odakyu Line. Multiple day-use facilities from ¥700. About 30 minutes by car from Tanzawa riverside spots.
• Nanasawa Onsen (七沢温泉) — Tucked into the eastern Tanzawa foothills. Several ryokan offer day-use bathing from ¥1,000. Strong alkaline water known for smooth skin.

For camping details, see our Tanzawa riverside camping guide. The river, the mountains, and a hot bath at sunset — hard to beat for free.

Hakone area: cheap sites near famous springs

Hakone is synonymous with hot springs but also with high prices. The trick is to camp on the outskirts and visit Hakone's bathhouses as a day guest. Several campgrounds in the ¥1,000-2,000 range sit within the greater Hakone area, putting you within reach of some of Japan's most famous spring water.

Hakone has over a dozen distinct spring sources, each with different mineral compositions. Day-use options range from ¥500 municipal baths to ¥2,000 luxury ryokan baths open to non-guests. Our Hakone glamping guide covers the luxury end, but the same springs are accessible on a camping budget.

Okutama: mountain camping + Moegi-no-Yu

Okutama, at the western end of Tokyo's JR Ome Line, has excellent camping and one standout onsen: Moegi-no-Yu (もえぎの湯). It is a 10-minute walk from Okutama Station, with indoor and outdoor baths overlooking the Tama River. Entry is ¥950.

Camp at one of the budget campgrounds along the Tama River (several are under ¥1,000), then walk to Moegi-no-Yu before catching the last train back. Or camp a second night and make it a full mountain weekend. The combination of JR access, cheap camping, and a quality onsen makes Okutama the most practical option for visitors without cars.

Tokyo Islands: free camps + volcanic springs

The Tokyo Islands offer something mainland Japan cannot: free campgrounds next to volcanic hot springs in a subtropical setting. Several islands have free public baths fed by natural geothermal activity.

• Hachijojima (八丈島) — Multiple free campgrounds plus several free or cheap outdoor onsen. Sokodo Campground (底土野営場) is free, and the island has at least four public baths including a free ocean-view rotenburo. Ferry or 55-minute flight from Tokyo.
• Izu Oshima — Free campgrounds (Toushiki, Umi no Furusato Mura) plus the Hama-no-Yu public bath near Motomachi Port. The combination of volcanic landscape, free camping, and ocean onsen is unique.
• Kozushima (神津島) — The island's public bath uses natural geothermal water. Camp at Takou-wan Family Campground (多幸湾公園ファミリーキャンプ場) for free and soak after a day of hiking.

Onsen tips for campers

• Bring a quick-dry towel — saves ¥200-300 on rental every visit
• Go before dinner — you will sleep better clean and warm
• Check tattoo policy — rural onsen are generally more relaxed, but confirm ahead. See our onsen etiquette guide
• Carry coins — many day-use onsen are cash only, and lockers require ¥100 coins
• Last entry is usually 30-60 min before closing — do not arrive at closing time
• Shampoo and soap are provided — at most paid facilities. Free outdoor baths may not have any
