Dump Stations and Water Supply Spots in Hokkaido (2026 Edition): 53 Places to Empty and Refill Your Camper Van Tanks

According to the Japan RV Association (JRVA), the number of certified RV Parks nationwide is expected to exceed 600 in 2026 (JRVA official site, “What is an RV Park,” confirmed July 31, 2026). Of these, 44 are certified in Hokkaido, listed on the official Kurumatabi RV Park site (same source, confirmed July 31, 2026). However, RV Park certification does not automatically mean a site has a dump station for wastewater or a fresh water supply — JRVA’s certification standard does not require a dump station. In this guide, we list 53 locations across Hokkaido where a dump station, a water supply, or both were confirmed through each facility’s own official information, organized by area.

All facility information below was confirmed as of July 31, 2026, based on each facility’s official website or the JRVA’s official “Kurumatabi” site. Where official sources did not clearly state whether equipment was available, we marked the item “Please confirm” rather than guessing. Prices, operating seasons, and usage conditions can change, so always confirm directly with the facility before you go. For an explanation of how camper van water systems work, see our Complete Guide to Camper Van Water Systems.

What’s in this guide: 53 locations, broken down by area

Alongside 44 certified RV Parks, we’ve added 9 roadside stations and campgrounds where a dump station or water supply was confirmed on the facility’s own official site, for a total of 53 locations. Here is the breakdown by area:

• Central Hokkaido: 22 locations (19 RV Parks, 3 others)
• Northern Hokkaido: 7 locations (4 RV Parks, 3 others)
• Eastern Hokkaido: 16 locations (14 RV Parks, 2 others)
• Southern Hokkaido: 8 locations (7 RV Parks, 1 other)

For a broader look at RV Parks across Hokkaido, see our 60 Recommended RV Parks in Hokkaido; for roadside stations, see 20 Recommended Roadside Stations for Car Camping in Hokkaido; and for campgrounds in general, see 89 Recommended Campgrounds in Hokkaido. This guide narrows that full list down to only the locations where a dump station or water supply is confirmed.

Finding a spot ① — “I need to empty my tanks as soon as I arrive”

If your grey tank (household wastewater) or black tank (toilet waste) is getting full, start by choosing a destination with a dump station. Look for facilities marked “Yes” in the “Dump Station” column of the tables below. If you’re new to how draining works, our Complete Guide to Camper Van Water Systems explains the mechanics and steps in detail — worth reading before your trip.

Of the 53 locations confirmed here, 16 had official confirmation of a dump station. Facilities listed as supporting “both black and grey tanks” can handle both toilet waste and sink drainage. Hose connections and drain locations vary by facility, so it’s safest to check with staff on arrival before draining.

Finding a spot ② — “I just need to refill water”

If refilling your fresh water tank is all you need, you have more options — you don’t need to worry about the dump station column at all. Water supply was confirmed at more than 40 of the 53 locations, and most of it is free. That said, some facilities set limits, such as “up to 20 liters” or “not for cooking or laundry use,” so check the notes in the “Water” column before heading over.

Whether the water is drinkable varies by facility. Unless a facility clearly states the water is “safe to drink,” it’s safest to treat it as suitable for cooking, dishwashing, or showers rather than drinking it directly.

Finding a spot ③ — “I want a place I can use without staying overnight”

Most of the locations listed here work on a pay-to-park-overnight model: you pay a nightly fee (roughly ¥2,000–¥5,000) to park at the site, and that gives you access to the dump station, water, power, and so on together. There are very few places where you can drop in just to use the dump station for free. Day-use drop-ins are really only realistic at a handful of roadside stations with dedicated water facilities.

Some facilities also have their own specific conditions, such as “Kurumatabi Club membership card required,” “reservation only,” or “vehicles larger than 4m × 7m cannot be accommodated.” Where the “Conditions” column notes something specific, always call or check the facility’s website before you arrive. General car-camping rules and etiquette are covered in our Complete Guide to Car Camping in Hokkaido.

Finding a spot ④ — “I want to know what’s open in winter”

Most RV Parks and campgrounds in Hokkaido close for winter at some point between late April and late October, or between early November and the end of April. Even facilities that advertise year-round operation may still close the water supply, showers, or dump station for winter alone, so don’t assume everything works just because a listing says “year-round” — check each piece of equipment’s winter status separately. For advice on cold-weather prep and finding a base for a winter camper van trip in Hokkaido, see Before You Take a Camper Van Trip in Winter Hokkaido.

The “Season” column in the tables below lists the specific closure periods and conditions exactly as stated in each facility’s official information. Even facilities marked “year-round” can have unscheduled closures depending on snowfall, so if you’re planning to use one in the depths of winter, call ahead the day before to confirm current status.

Central Hokkaido: Dump Stations and Water Supply Spots (22 locations)

Central Hokkaido — covering Sapporo, Ishikari, Shiribeshi, Iburi, Sorachi, and Hidaka — has more certified RV Parks than any other area, with 19 in total. We’ve also added 3 campgrounds where a dump station was officially confirmed. For a broader look at RV Parks in this area, see our 60 Recommended RV Parks in Hokkaido.

Northern Hokkaido: Dump Stations and Water Supply Spots (7 locations)

Northern Hokkaido — covering Asahikawa, Furano, Biei, Nayoro, and Wakkanai — has only 4 certified RV Parks, but we found 3 more roadside stations and campgrounds with confirmed dump stations or water supply, for 7 locations total.

Eastern Hokkaido: Dump Stations and Water Supply Spots (16 locations)

Eastern Hokkaido — covering Kushiro, Nemuro, Tokachi, and the Okhotsk coast — has 14 certified RV Parks, plus 2 prefectural-park campgrounds. If your route includes Shiretoko or Lake Akan, it’s worth building in a stop at a “Yes” dump-station facility ahead of time.

Southern Hokkaido: Dump Stations and Water Supply Spots (8 locations)

Southern Hokkaido — covering Hakodate, Hokuto, and the Hiyama region — has 7 certified RV Parks and 1 campground. This area is convenient right after arriving in Hokkaido by ferry, or on your final stretch before heading back to Honshu.

5 rules to confirm before you go

The information in the tables above was confirmed as of July 31, 2026. To avoid surprises on the ground, confirm these five points yourself before you set out.

• Confirm current operating status by phone or website: several facilities have irregular or temporary closures
• Confirm what the dump station accepts: whether it handles both black and grey tanks, or grey only, changes your procedure
• Confirm water supply limits: some free taps still cap usage, such as “up to 20L” or “not for cooking or laundry”
• Confirm usage conditions: if membership, reservations, or vehicle-size limits apply, contact the facility the day before rather than same-day
• Confirm winter equipment status: some “year-round” facilities still close just the water supply or dump station for winter

General car-camping etiquette and waste disposal practices are covered in our Complete Guide to Car Camping in Hokkaido, and tips for basing your trip around roadside stations are in 20 Recommended Roadside Stations for Car Camping in Hokkaido.

What about draining tanks before returning a rental camper van?

If you’re on a rental camper van trip, returning it with a full grey or black tank can mean extra cleaning fees. Stopping at one of the dump-station facilities listed in this guide the day before or the morning of your return makes the return process much smoother.

Our Camper Van Rental Return Checklist covers the cleaning, water system, and refueling steps to check before you return your vehicle. If you’re returning near New Chitose Airport or Sapporo, working one of the Central Hokkaido locations into your route saves you a detour.

Summary: Decide on your dump station and water spot before you leave

The key to never getting stuck on water or waste during a Hokkaido camper van trip is simple: decide on one or two dump-station or water-supply spots along your route before you set out. The 53 locations in this guide were all confirmed through official information as of July 31, 2026, but prices, operating seasons, and usage conditions can change — always confirm directly with the facility before you go. Where we’ve marked an item “Please confirm,” treat it as neither confirmed yes nor no, and build your itinerary around checking it on-site or by phone.

Frequently Asked Questions

What’s the most efficient way to plan a route around dump-station facilities?

Check the “Dump Station” column marked “Yes” in the Central, Northern, Eastern, and Southern Hokkaido tables above, and pick one or two facilities that sit along your route. Some RV Parks require advance reservations, so it’s worth calling as soon as your travel dates are set.

Are there any free spots if I only need to refill water?

Water supply was confirmed at more than 40 of the 53 locations here, and most of them are free. That said, some cap usage at things like “20L maximum,” and others require an overnight stay, so check both the “Water” column notes and the “Conditions” column together.

Are there facilities I can use without staying overnight?

Most listed facilities operate on a pay-per-night parking model, so dropping in for free just to use the dump station generally isn’t possible. Some require a membership card or advance reservation, so always check the “Conditions” column before heading over.

How can I tell which facilities are open if I’m visiting in winter?

The “Season” column lists the exact closure periods confirmed from each facility’s official information. Even facilities marked “year-round” sometimes close just the water supply or dump station for winter, so if you’re planning to visit in the depths of winter, call the day before to confirm current status.
