Tomakomai’s Only RV Park: Itoi no Mori — Rates, Booking, and 4 Nearby Backups When It’s Full [2026]

There’s only 1 certified “RV park” you can stay at inside Tomakomai city. Checking the Hokkaido list of 45 RV parks certified by the Japan RV Association (JRVA), as published on the official kurumatabi.com directory, against every municipality name, RV Park Itoi no Mori is the only one located in Tomakomai city (confirmed August 4, 2026). Tomakomai is Hokkaido’s gateway, with 3 ferry routes converging on it — yet there’s just 1 certified overnight-parking facility.

Having only 1 option means you need a backup plan ready before it fills up. This article covers Itoi no Mori’s rates, facilities, and booking method, plus 4 nearby facilities (Atsuma, Chitose, Eniwa, and Muroran) you can use when it’s full.

The rates, facilities, and booking methods in this article were confirmed on August 4, 2026, using the kurumatabi.com official site’s facility pages and each facility’s own official page. Rates and acceptance conditions can change, so please check each facility’s latest information before booking.

Tomakomai’s Only RV Park Is “Itoi no Mori”

An RV park is a designation for overnight-parking facilities certified by the Japan RV Association (JRVA) — it’s not a name anyone can just use. The kurumatabi.com official site, which lists certified facilities, states that “a facility certified by the Japan RV Association becomes an RV Park” (confirmed August 4, 2026). For how this differs from a Michi-no-Eki or a campsite, see What Is an RV Park? Rates, Facilities, and How It Differs From a Michi-no-Eki.

The figure “just 1 in Tomakomai city” comes from checking every one of the kurumatabi.com Hokkaido list’s 45 facilities against its municipality name, one by one (confirmed August 4, 2026). All 45 facilities across Hokkaido are compared on rates, power, and onsen access in Hokkaido RV Parks: The Full List of 45 JRVA-Certified Sites.

Beyond certified RV parks, there are also campgrounds and paid parking lots that accept overnight vehicle stays. The “1” in this article refers strictly to the count of JRVA-certified RV parks.

RV Park Itoi no Mori: Rates, Facilities, and Booking

At ¥2,500 a night, it’s a standard rate compared to Sapporo’s 3 facilities (¥1,500–¥4,000). Powered sites are limited to 4, so if you want power, confirm availability when you book. Details are on the kurumatabi.com facility page.

There’s no bath on-site. The nearest bathing facility listed is the onsen “Tomakomai Onsen Honoka” (4.3 km away), among others (confirmed August 4, 2026). You’ll need to bathe first, then come back to sleep.

One thing worth noting: Itoi no Mori has no official website of its own. Its only official channel is an X (formerly Twitter) account, where operating-status announcements are also posted (confirmed August 4, 2026). Booking by phone is the surest route. Same-day use is accepted with a reservation by 5:00 PM, so making one phone call before your ferry departs or while you’re en route makes things much easier.

Can You Use It the Day You Arrive or Depart by Ferry?

Most people searching for an RV park in Tomakomai are looking for a ferry stopover, before or after their sailing. Whether it works depends on your arrival and departure times. Since Itoi no Mori’s same-day booking cutoff is 5:00 PM, it pairs well with ferries that reach Tomakomai by evening or depart the next morning — but you can’t book same-day after arriving late at night. If you’re arriving late at night or early morning, finish your booking before boarding and call ahead to say your arrival will be late (check-in hours weren’t stated in official information, so confirm this when you book).

If your plan is to rent a campervan after arriving by ferry, the first thing to sort out is whether the 3 ferry routes’ arrival times line up with rental shop hours. That comparison is covered in Can You Rent a Campervan in Tomakomai Right After Your Ferry Arrives?, which also covers staying overnight in your own vehicle and picking up the rental the next morning if you can’t collect it on arrival day.

When Itoi no Mori Is Full: 4 Nearby Options

Having just 1 facility in the city can only be offset by having a backup ready. Around Tomakomai, there are certified RV parks in Atsuma to the east, Chitose and Eniwa toward New Chitose Airport, and Muroran to the west.

All figures confirmed August 4, 2026. Direction of travel and bathing are the deciding factors. If you’re heading toward Hidaka or Erimo the next day, RV FOREST 310 in Atsuma fits your route; if you’re picking up or returning your vehicle at New Chitose Airport, Shin-Chitose Airport BASE or Hana Road Eniwa lines up better. If you want to walk to an onsen, only Muroran ZEKKEI BASE CAMP meets that condition — the neighboring “Muroran Onsen Yurara” is about a 1-minute walk away (confirmed August 4, 2026). Just note that booking cutoffs and methods vary: Hana Road Eniwa needs 3 days’ notice, and ZEKKEI BASE CAMP is online-only.

If you’re extending your trip toward Sapporo, Sapporo RV Parks: Only 3 in the City gives you your next stopover; crossing the Hidaka mountains into Tokachi, Obihiro & Tokachi’s 4 Certified RV Parks does the same. To search all of Hokkaido by area, open Hokkaido RV Park List: All 60 Sites.
