I Looked Into Okuchichibu Kaniwa Auto Campsite

Researching campsites, day-trip hot springs, and lodges one by one and writing them up on the blog is something I've kept doing throughout Komorin's Fantasy Travels. I've lost count of how many campsites in Saitama Prefecture I've covered by now.

This time I looked into "Okuchichibu Kaniwa Auto Campsite." What first drew me in was learning that the name is pronounced "Kaniwa." I also came across information suggesting the facility used to go by a slightly different name, but it seems the official website now consistently uses this current name.

The Short Version

My impression was that this campsite has quite a lot of kid-friendly playground equipment, like a bouldering wall and a pool in an artificial pond.
The Rakuten Mobile signal was rated a C by the official tool, so the result wasn't exactly great.

I've summarized the details below.

What Kind of Place Is Kaniwa Auto Campsite?

This is an auto campsite located in Otaki, Chichibu City. It's apparently open year-round, though it closes in January and February. There are also apparently a few scheduled closure days in May and September of 2026, so it might be a good idea to check the official website's announcements before heading out.

Check-in is apparently from 12:00 for overnight stays and from 11:00 for day camping, with check-out at 11:00 and 16:00 respectively. Using the facility outside these hours seems generally difficult, though it sounds like arrangements might sometimes be possible depending on availability.

The pricing structure seems to be broken down in detail depending on the type of site. Roughly summarized, it looks something like this:

Sites A and C: from 4,500 yen without power, from 5,500 yen with power (varies by season)
Sites B and D: from 5,000 yen without power
Site E: from 5,000 to over 9,000 yen depending on the plot, from 19,000 yen for groups
Solo sites: weekdays only, 3,000 to 3,500 yen, plus 1,000 yen for power
Day camping: from 2,500 yen for one car with up to 5 people
Additional guests: 1,000 yen per person/night for junior high age and up, 500 yen per person/night for ages 3 through elementary school
Trash disposal: 500 yen for one designated trash bag (apparently you can also take your trash home with you)

Payment is apparently cash only, which was a bit surprising to me as someone who leans cashless. As for reservations, it seems phone bookings used to be the only option, but apparently starting from August 2025 there's been an announcement that overnight bookings will gradually shift to online reservations. That said, at the time of writing this article I haven't been able to confirm exactly how far along that transition is, so it's probably safest to check the official website for the latest information, including whether phone reservations are still available.

Cash only might quietly be a stress point for someone like me who's pretty dependent on going cashless. I'll need to make sure I've got enough cash ready beforehand.

Facilities Worth Checking as an Indoor Type

The restrooms are apparently flush toilets fully equipped with washlets, which was pretty reassuring news for me as an indoor type. There's also apparently a coin shower available 24 hours a day (200 yen for 4 minutes), though it seems to be unusable during winter (December through March) to prevent freezing.

You can apparently choose between Sites A and C for powered sites, available for an extra 1,000 yen compared to sites without power. I couldn't find any mention of power hookups for Sites B and D, so anyone who needs power might want to keep that in mind when choosing a site. I wasn't able to find any mention of Wi-Fi on the official website, so that seems to remain unclear for now.

What struck me as unique to this facility was the range of play equipment on site, including a bouldering and obstacle course area, a giant Othello board, a slide, and a pool in an artificial pond. It's apparently designed so even small children can play safely, which seems like it would be a great fit especially for families.

Pets are apparently allowed, with a leash required outdoors and a cage required indoors. That said, there seem to be a few restrictions when bringing pets, such as not being able to rent blankets or sleeping bags, so it's probably worth checking in advance. Open fires directly on the ground aren't allowed, but apparently you can have a campfire using a designated raised fire pit. Handheld fireworks are apparently allowed for overnight guests only.

Rakuten Mobile Signal Conditions

When I checked this facility's location using the official My Area Connectivity Simulation tool, the overall rating came back as "C."

Since this is a campsite in a mountainous area, connectivity likely varies depending on exactly where you are on the grounds. If you're planning to use your phone for emergency contact or work-related communication, it might be worth checking this in advance for peace of mind.

Komorin

A C rating is just something I have to accept honestly. Maybe it's better to think of it as proof you've really gotten out into nature, and treat it as a chance to intentionally step away from your phone for a while.

Nearby Hot Springs and Sightseeing Spots

About a 5-minute drive away is a roadside station called "Michi-no-Eki Otaki Onsen," which apparently includes a day-trip hot spring called "Yuyukan" and a soba restaurant called "Gorokan." The campsite apparently hands out discount coupons for Yuyukan to overnight guests, so soaking in a bath after camping sounds like a nice option.

There's also a trout fishing spot called "Ochichigawa Keiryu Fishing Park" about a 7-minute drive away, where you can apparently enjoy stream fishing as well as grilled char and yamame trout. During winter only, there's also an ice formation spot called "Misotsuchi no Tsurara," about a 10-minute drive away. If you're willing to go a bit further, spots like "Chichibu Geo Gravity Park," "Mitsumine Shrine," and "Chichibu Muse Park" all appear to be within about a 20-25 minute drive.

Wrapping Up

Pulling it all together, my overall impression of Okuchichibu Kaniwa Auto Campsite was that it's a campsite well-stocked with fun equipment like obstacle courses and a pool, making it a good fit for families. Basic facilities like the restrooms and showers seem solid too, which is reassuring for an indoor type like me, though it's worth keeping in mind ahead of time that payment is cash only and that Wi-Fi availability is unclear.

As for the Rakuten Mobile signal, the simulation tool gave it a C rating. If you're concerned about connectivity, it might be reassuring to check the official tool beforehand.
