Kamishihoro & Naitai Highland Ranch by Campervan | Balloon Country and a Scenic Ranch Drive [2026 Edition]

Naitai Highland Ranch in Kamishihoro sprawls across roughly 1,700 hectares (about 358 Tokyo Domes) — Japan’s largest public ranch. According to the official site of karch, the company that operates the ranch, cattle taken in from within and outside the town graze here, numbering around 2,000 head (karch official site, confirmed 2026-08-25). Some sources put the summer figure, including horses, at over 2,700 (Ministry of Agriculture, Forestry and Fisheries, confirmed 2026-08-25). From “Naitai Terrace,” a viewpoint at roughly 800m elevation overlooking the grazing land, a driving road runs about 7km from the entrance gate (karch official site, confirmed 2026-08-25).

You feel the scale of this place best by driving a campervan slowly up that slope. Reaching the observation deck isn’t the end of it — the drive along the edge of the ranch itself is the scenery. That said, since it’s a road that climbs from the entrance gate to 800m elevation, it’s worth knowing the operating season, parking situation, and how easy it is to pass oncoming traffic before you go.

This article gathers official information on Naitai Highland Ranch and Naitai Terrace — area, head count, operating season, and parking — as confirmed as of 2026-08-25, along with points to watch when driving a campervan there, how to think about staying overnight beforehand, how to combine the trip with Lake Nukabira and the Taushubetsu River Bridge, and how to plan around the hot-air balloon experience available in the same town.

What is Naitai Highland Ranch? Japan’s largest public ranch, at 1,700 hectares with around 2,000 head grazing

Naitai Highland Ranch is a public ranch managed by the town of Kamishihoro. The town’s official tourism site describes it as “one of Japan’s largest public ranches, with a total area of about 1,700 hectares (about 358 Tokyo Domes), where you can watch cattle grazing” (Kamishihoro town official site, confirmed 2026-08-25), and the same figure is echoed by both a Ministry of Agriculture, Forestry and Fisheries document and the official site of karch, which operates Naitai Terrace (MAFF, karch official site, confirmed 2026-08-25).

The number of grazing cattle varies somewhat between sources. karch’s official site states that “cattle entrusted from within and outside the town (around 2,000 head) graze on the ranch” (confirmed 2026-08-25), while the MAFF document states that “in summer, over 2,700 head of cattle and horses graze on the grassland” (confirmed 2026-08-25). The difference is likely explained by horses being included in the summer count, but the exact breakdown can’t be pinned down from the official sources.

Naitai Highland Ranch isn’t a tourist petting ranch — it’s a facility specializing in raising entrusted young cattle. According to the MAFF document, dairy cattle at least 6 months old are taken in from their owners, raised and inseminated, then returned to their owners as pregnant cattle close to calving (confirmed 2026-08-25). The cattle you see as you drive through the ranch aren’t there for show — they’re part of this custody-and-raising operation.

Can you drive the Rainbow Road in a campervan? About 7km from the entrance gate to 800m elevation

You reach Naitai Terrace by climbing the road known as “Rainbow Road,” which runs from the ranch’s entrance gate to the summit. karch’s official site describes it as “a spectacular roughly 7km driving road that climbs from the entrance gate to 800m elevation” (confirmed 2026-08-25). Specific figures that would let you judge whether larger vehicles can pass — road width, number of sharp curves — aren’t listed on the official site, and we weren’t able to confirm them for this article either.

If you’re heading up in a campervan, the safer approach is to drive at a speed that assumes you’ll need to pass oncoming traffic, treating the road details we couldn’t confirm on the official site — width, pull-off spots, steep sections — as unknowns. If you’re driving a wider vehicle, it’s worth checking road conditions in advance with the Kamishihoro town office (01564-2-2111) or the Kamishihoro Tourism Association.

What are the operating dates and hours? Naitai Terrace runs April 25 to October 31 in 2026

Naitai Terrace’s 2026 operating period runs from April 25 to October 31, with hours of 9:00 AM to 5:00 PM (Kamishihoro town official site, confirmed 2026-08-25). During that period it’s described as open daily, “subject to change due to weather” (confirmed 2026-08-25). karch’s official site lists the ranch entrance gate’s opening hours as 7:00 AM to 6:00 PM (until 7:00 PM from June through September), with the ranch’s overall operating period running from late April to the end of October (confirmed 2026-08-25).

In other words, the gate is closed in winter (roughly November through mid-April), and you cannot drive a campervan into the ranch during that time. This article isn’t meant for a snow-season Hokkaido touring plan — if you’re visiting, plan for late April through October. Since the start and end dates can shift year to year, check the latest period on the Kamishihoro town official site or Naitai Terrace’s own notices before you set out.

Where’s the parking? A breakdown of 74 regular and 6 large-vehicle spaces

According to karch’s official site, Naitai Terrace’s parking lot breaks down into 74 spaces for regular vehicles, 6 for large vehicles, and 3 reserved for accessible parking (confirmed 2026-08-25). The Kamishihoro town official site lists it as “available (approximately 80 spaces)” (confirmed 2026-08-25), which roughly matches. Cabcon- and buscon-type vehicles that exceed the size of a typical passenger car are meant to use the large-vehicle spaces (6 total), so it’s worth planning your visit time with that small number in mind.

With only 6 large-vehicle spaces, the lot could fill up during busy periods such as summer weekends, the Obon holiday, or the autumn foliage season. Since a full lot could mean waiting to pass oncoming traffic on Rainbow Road itself, visiting early in the morning or on a weekday gives you more margin to find a space.

When’s the best time to see the grazing scenery? Why summer is considered best

Naitai Highland Ranch operates from late April to the end of October, but the view of cattle spread across the vast grassland is easiest to see in summer, once the grass has grown and grazing is in full swing. Since the ranch itself closes in winter, the “ranch” scenery that’s the statistical anchor of this article isn’t visible during the snow season. We couldn’t find an official source stating the exact start and end of the grazing period, so if you want to narrow your visit to summer specifically, check directly with the Kamishihoro Tourism Association.

Being a highland at 800m elevation, it runs cooler and windier than the flatlands of Tokachi below. Bringing a jacket even in midsummer makes time at the observation deck more comfortable. Since operating hours can change with the weather (Kamishihoro town official site, confirmed 2026-08-25), checking the day’s forecast before you set out can save you a wasted trip.

What can you do at Naitai Terrace? A view café, souvenirs, and a restroom break

Naitai Terrace is a floor-to-ceiling glass observation facility with a view café and a shaded terrace (Kamishihoro town official site, confirmed 2026-08-25). It also serves as a rest facility with souvenir sales and is equipped with an AED (confirmed 2026-08-25). We couldn’t find specific details on the café’s menu or pricing on the official site, so check on site.

On a campervan trip, whether you can secure a restroom and a short break along the way shapes your itinerary. Naitai Terrace sits at the end of a roughly 14km round trip, and being able to rest, get a drink, and pick up souvenirs there makes it a well-placed spot to catch your breath after the climb.

How to get there from Obihiro: heading north to Kamishihoro on Route 241

Kamishihoro sits in northern Tokachi, north of central Obihiro along National Route 241, and the roadside station Michi-no-Eki Kamishihoro is also on Route 241. That said, we couldn’t confirm an official source for the exact distance or travel time from Obihiro to the entrance of Naitai Highland Ranch. Since map-app route searches vary with road conditions, this article doesn’t state a specific number of minutes or kilometers — we’d recommend checking your car navigation or map app for the latest route before you set out.

For touring the Obihiro/Tokachi area more broadly, see The Obihiro/Tokachi Campervan Driving Guide. If you’re folding Kamishihoro into a wider Tokachi loop rather than visiting it on its own, check that guide as well.

Where to stay the night before: the situation at Michi-no-Eki Kamishihoro and RV park options

Naitai Terrace opens at 9:00 AM. If you want to catch the ranch early in the morning, or arrive with margin after a long drive the day before, staying overnight nearby is realistic. Michi-no-Eki Kamishihoro sits along Route 241 within the town, but we couldn’t find anything on the roadside station’s official site stating whether overnight parking is allowed there (confirmed 2026-08-25). If you plan to park overnight, check directly with the facility, or choose a facility that explicitly states it accepts overnight parking.

For a reliable option, there are 4 JRVA-certified RV parks in the Obihiro/Tokachi area (for rates, power, and booking, see 4 JRVA-Certified RV Parks in Obihiro/Tokachi; confirmed 2026-08-25). To search across all of Hokkaido, use A List of Hokkaido RV Parks (45 JRVA-Certified Sites). Whether Kamishihoro itself has a certified RV park is something we couldn’t confirm within the scope of this article.

Can you combine it with Lake Nukabira and the Taushubetsu River Bridge? A one-day Kamishihoro driving model route

Kamishihoro isn’t just home to Naitai Highland Ranch — it also includes the Lake Nukabira and Taushubetsu River Bridge area, where a series of arch bridges from the former Japanese National Railways Shihoro Line still remain. The Kamishihoro Tourism Association lists the Taushubetsu River Bridge as one of the town’s signature scenic spots (confirmed 2026-08-25). Note, though, that how much of the bridge is visible changes with the dam’s water level, and it’s known to sink below the lake’s surface entirely when the water level rises. Check the Kamishihoro Tourism Association’s latest updates for how visible the bridge is during your visiting season.

If you want to fit both the ranch drive and the arch bridges into the same day, one approach is to visit the high-elevation Naitai Terrace in the cool morning hours and take the Lake Nukabira area at a relaxed pace in the afternoon. For an itinerary that also loops through Lake Shikaribetsu and Tokachigawa Onsen, see A 2-Night, 3-Day Route Through Lake Shikaribetsu and Tokachigawa Onsen by Campervan; for a route spanning a wider stretch of eastern Hokkaido, see A Model Route for Touring Eastern Hokkaido by Campervan.

If you’re considering a trip centered on hands-on encounters with animals, see Touring Hokkaido’s Ranches by Campervan, which covers milking and cheese-workshop experiences — reading both makes clear the difference between an experience-based trip and a scenery-based one. Naitai Highland Ranch is a raising-and-custody facility, and its official site doesn’t list hands-on programs such as milking.

Can you plan it alongside Tokachi’s hot-air balloons (the Kamishihoro balloon festival)?

Kamishihoro is also a hot-air-balloon town, hosting the “Hokkaido Balloon Festival” every August. The Kamishihoro Tourism Association’s site states that “the 53rd Hokkaido Balloon Festival is scheduled for 3 days, August 7–9, 2026” (confirmed 2026-08-25), meaning the 2026 festival has already ended. The festival is a competitive event that draws balloons from across the country, and it’s a separate undertaking from the scenic ranch drive covered in this article.

If you’d like to try a hot-air balloon free flight on your own in autumn, the general flights operated by Hot air in neighboring Shikaoi Town are an option. Rates, meeting points, and how to think about staying overnight before an early-morning gathering time are covered in Tokachi’s Hot-Air Balloons Peak in Autumn: Free-Flight Experiences and Campervan Overnight Tips for September–November. Watching the balloon festival in August, taking a free flight yourself in September–November, and driving the Naitai Highland Ranch scenery year-round are three genuinely separate trips worth planning independently.

What to check before you set out

• Whether your planned visit date falls within Naitai Terrace’s operating period (April 25–October 31 in 2026, subject to change due to weather)
• Whether your schedule fits within the ranch entrance gate’s opening hours (7:00 AM–6:00 PM, until 7:00 PM June–September)
• Whether you can expect parking given your vehicle size (only 74 regular and 6 large-vehicle spaces)
• Whether you’ve decided where to stay the night before (confirm directly with the roadside station whether overnight parking is allowed; a JRVA-certified RV park is the reliable option)
• Whether you’ve packed a jacket for the temperature difference at 800m elevation
• If visiting Lake Nukabira and the Taushubetsu River Bridge the same day, whether you’ve checked the latest water-level visibility with the tourism association
• Whether you’ve re-confirmed with the official sites just before your trip, since the figures in this article are current as of 2026-08-25

Frequently asked questions

What kind of ranch is Naitai Highland Ranch?

It’s Japan’s largest public ranch, covering roughly 1,700 hectares (about 358 Tokyo Domes) (Kamishihoro town official site, confirmed 2026-08-25). It’s a custody facility that takes in young dairy cattle from their owners, has them raised and inseminated, and returns them close to calving — the official site doesn’t list hands-on programs like milking that you’d find at a tourist ranch.

Roughly how many cattle are grazing there?

Operator karch’s official site lists around 2,000 head (confirmed 2026-08-25). A Ministry of Agriculture, Forestry and Fisheries document also states that over 2,700 head, including horses, graze in summer — the figure varies by source, and the exact breakdown can’t be pinned down from official materials.

Can you drive a campervan up to Naitai Terrace?

It’s a roughly 7km driving road from the entrance gate up to 800m elevation (confirmed 2026-08-25). Specific figures for judging whether larger vehicles can pass — road width, number of sharp curves — aren’t listed on the official site. If you’re concerned, check road conditions in advance with the Kamishihoro Tourism Association.

What are the operating dates?

Naitai Terrace’s 2026 operating period runs April 25–October 31, with hours of 9:00 AM–5:00 PM (confirmed 2026-08-25). The ranch entrance gate is open 7:00 AM–6:00 PM (until 7:00 PM June–September), and it’s closed for winter.

Can a large campervan park there?

Naitai Terrace’s parking lot breaks down into 74 regular spaces, 6 large-vehicle spaces, and 3 accessible spaces (karch official site, confirmed 2026-08-25). With only a handful of large-vehicle spaces, we’d suggest shifting your visit time to account for the lot potentially filling up during busy periods.

Where should we stay the night before?

Michi-no-Eki Kamishihoro is within the town, but we couldn’t find anything on its official site stating whether overnight parking is allowed (confirmed 2026-08-25). If you plan to park there, check directly with the facility, or use one of the 4 JRVA-certified RV parks in Obihiro/Tokachi that explicitly accept overnight stays.

Can we combine it with Lake Nukabira or the Taushubetsu River Bridge?

Since they’re within the same town, you can combine them in a single day. That said, how much of the Taushubetsu River Bridge you can see changes with the dam’s water level, so check the Kamishihoro Tourism Association’s latest updates for your visiting season. For a sample loop, see A 2-Night, 3-Day Route Through Lake Shikaribetsu and Tokachigawa Onsen by Campervan.

Can we also enjoy Kamishihoro’s hot-air balloon experience?

Kamishihoro’s “Hokkaido Balloon Festival” is an annual competitive event held every August, and the 2026 edition, held August 7–9, has already ended (Kamishihoro Tourism Association, confirmed 2026-08-25). If you’d like to fly a free flight yourself, the general flights run by Hot air in neighboring Shikaoi Town are an option. See Tokachi’s Hot-Air Balloons Peak in Autumn for details.
