I Looked Into Rising Field Karuizawa

On this blog, I've been researching campsites one after another, from permanent lodges to free sites for advanced campers, and I feel like the range of facilities I've covered has really expanded by now.

This time I looked into Rising Field Karuizawa. I'd seen the name come up many times before, but the fact that it has both permanent lodges and free sites for advanced campers all within the same facility caught my attention, so I decided to sit down and really dig into it.

What Kind of Place Is Rising Field Karuizawa?

This is a campsite located in Karuizawa, Kitasaku District, Nagano Prefecture, apparently an outdoor resort spread through a forest with a view of Mt. Asama. The center house's business hours are 8:30 AM to 5:00 PM, and it seems the restrooms, diaper-changing area, nursing room, and kids' restroom are available 24 hours.
The breakdown of the 2026 season into regular period, high season, and closed days is posted as an image on the official website, so I wasn't able to confirm specific dates from the text. If you're considering a visit, it looks like you'll need to check the image table on the official site directly.

As for pricing, I couldn't confirm the actual campsite rates this time since they're shown as an image, but the following fees were listed in the text.

• BBQ corner usage fee: 1,100 yen (tax included) per adult for 2 hours (free for junior high school age and under; kids cannot use it without an adult)
• Early check-in / late check-out: 1,100 yen per hour per site
• Owl Adventure (sky athletic course): High course (2–8m) 3,630 yen for 2 hours, low course (2–4m) 2,860 yen for 2 hours

Apparently, reservations for overnight sites are made through an external booking site, while activities and BBQ are booked through a Wix reservation calendar, and it seems you can also book by phone. As for the standard check-in and check-out times, I found the extra fees for early/late arrangements, but I couldn't find the standard times themselves in the text, so that's another point I'd want to check.

Having the price list as an image feels like a bit of a hurdle for an indoor type like me. If you're planning to actually visit, it seems like a good idea to carefully check the images on the official site too.

Site Layout: From Permanent Lodges to Fields for Advanced Campers

I felt like the biggest characteristic of this campsite is how finely the site types are divided by skill level. Broadly categorized by how well-equipped they are, the layout seems to be as follows.

• For beginners (permanent, with power): container-based Salvage Lodges, American garage-style Garage Lodges, and large tents called Ridge Lodges that accommodate up to 8 people — apparently these are all standalone spaces equipped with a shower, toilet, and floor heating
• For beginners to intermediate campers (auto sites with power): the 10m x 10m Center Field (RV-compatible), and the shady Sweet Field (limited to 6 sites)
• For intermediate to advanced campers (free sites with no power): Sky Field, with a full view of Mt. Asama; Forest Field, in the woods; and the 5m x 5m Bushcraft Field, where open fires are allowed
• Other facilities include TAKIBI BASE, dedicated to open fires; the Center House, which serves as the general reception and store; and Cafe & Bar Moon Bear

There also appears to be an on-site hot spring called Oze Onsen that's available exclusively to overnight guests, though I wasn't able to confirm whether it's actually within the facility grounds or a separate, adjacent facility. Rental gear is said to include everything from tents and lanterns to kitchen supplies, so it seems easy to use even if you're traveling nearly empty-handed.

Can You Get There Without a Car? I Looked Into Access

Even though I technically have a driver's license, I'm essentially someone who never drives, so non-car access options are always a point of interest for me. From what I found, you can take a bus from Karuizawa Station heading toward Kusatsu Onsen for about 15–20 minutes and get off at a stop called Rising Field Karuizawa. By taxi, it seems to take about 10 minutes from Karuizawa Station.
Since the shinkansen from Tokyo Station to Karuizawa Station takes about an hour, it seems like a distance you could manage without a car if you connect by train.

If you're heading there by car, the guidance suggests about 35–45 minutes from the Usui-Karuizawa IC via a toll road called Shiraito Highland Way, which apparently can't be used on foot, by bicycle, or by motorbikes under 125cc. If the facility name doesn't come up in your car navigation system, the advice is to set a nearby hot spring facility's name instead.

Rakuten Mobile Signal Conditions

I tried to check the location of this facility using the official "my area Network Coverage Simulator," but this time I couldn't pin down a matching address candidate, so I wasn't able to confirm either the measured results or the assessment. Since the facility is spread through a forest, there's likely some variation in signal strength depending on the area, too.

Since I wasn't able to confirm this to the point of stating a clear result this time, I'll just leave it noted as-is. If you're planning a visit, it seems like a good idea to run the simulation yourself beforehand with your own device and the specific location you'll be using it.

As a Rakuten Mobile user myself, this is the part I care about most, so it's a little frustrating that I couldn't get a clear verdict. I'm hoping to add an update once I find out more.

Wrapping Up

To sum it up again, my impression of Rising Field Karuizawa is that it's an outdoor resort that's easy to use regardless of your camping experience, offering everything from permanent lodges with floor heating to advanced-level fields where you can have an open fire. The fact that it seems accessible by bus or taxi is a point I really appreciate, given that I don't drive.
That said, there were a few things I'd want to double-check myself beforehand, like the fact that the price list was only shown as an image, and that I couldn't confirm Rakuten Mobile signal conditions this time. If you're considering a visit, be sure to check the latest information on the official website as well.
