I Looked Into Okuchichibu Auto Campsite Suzukaen
2026-09-03

This blog keeps digging into campsites, day-trip hot springs, and lodging facilities, but this time I picked up something a bit unusual for an indoor type like me: an "auto campsite." It's a facility built around the assumption that you'll be driving, so even though I have a license, being more of a paper driver made it feel a little out of reach for me. Still, once I started researching, I found some interesting points about walking access and the facilities attached to it, so I decided to put together an article.
This time I looked into "Okuchichibu Auto Campsite Suzukaen." Just going by the name, it looked like it might be a different facility from "Masakado Falls Auto Campsite," but after doing some research, it seems the name is written slightly differently across sources while actually referring to the same location. There's apparently a restaurant right next door known for its stone-grilled dishes, so that point caught my attention too and I dug a bit deeper.
This auto campsite has sites with AC power, plus an adjacent restaurant serving stone-grilled dishes, so it seems like a spot where you can enjoy both camping and dining.
Rakuten Mobile's official tool rated the signal here as a C, so it seems like connectivity is something to be a bit cautious about.
I've put together the details below.
What Is Okuchichibu Auto Campsite Suzukaen Like?
This is an auto campsite located in the Arakawa area of Chichibu City, Saitama Prefecture. It's apparently run by the same operator as a restaurant called "Okuchichibu General Leisure Center Kinoko no Sato Suzukaen." It seems to have previously been introduced under the name "Masakado Falls Auto Campsite" as well, but as far as I could tell from my research, both names point to the same site. It's located along the Arakawa River, and being able to play in the river also seems to be one of the characteristic features of this place.
The operating season runs from April 1 to November 30, and apparently the site is closed during winter (December through the end of March) due to freezing. There's also a notice about being closed on Tuesdays, so it seems worth keeping that in mind if you plan to visit. Check-in is from 9:30 on Saturdays only, and from 10:00 on other days, and it seems arriving after 17:00 is difficult either way. Reservations are apparently accepted by phone only, and it seems reservations open starting March 1 of the year of use.
As for pricing, one auto camping plot (including 4 adults and 1 car) is 6,000 yen, with a seasonal rate of 7,000 yen. Additional guests are apparently 800 yen for adults and 500 yen for children, pets are 200 yen, and using AC power costs 1,100 yen per night. There are also 8 bungalows available, priced at 11,000 yen each (12,000 yen during the seasonal rate). For day-trip use without a car, there's apparently also a day camp rate (800 yen per car, 800 yen per adult, 500 yen per child).

Phone-only reservations feel a bit intimidating when you're used to booking online. Still, since the reception hours are clearly stated, jotting them down ahead of time should put your mind at ease.
Checking the Facilities That Matter to an Indoor Type Like Me
The first things I checked were the restrooms and the cooking area. The official site clearly states there are flush toilets and a cooking area, so it seems the basic facilities are in place. That said, I couldn't find details about whether there are washlets or how clean things are, so that part remains unclear.
- Power sites: Apparently there are 6 sites with AC power available (each plot 6x8m)
- Wi-Fi: There's no mention of it on the official site, so it's unclear whether it's available
- Bathing: There's no large communal bath or hot spring on site, but hot water showers are apparently provided
- Shop: Located inside the management building, apparently offering vending machines as well as rental items like charcoal, grill nets, and griddles
- Pets: Apparently allowed with an application and approval, but they can't be brought inside the bungalows
- Campfires: Apparently allowed except during part of the busy season
The possibility that there's no Wi-Fi is a bit of a concern for someone as indoor-oriented as me. It's probably worth considering this alongside the signal conditions section below.
Stone-Grilled Dishes at the Adjacent Restaurant
Another highlight of this facility seems to be the restaurant attached to the property, called "Kinoko no Sato Suzukaen." It's apparently known for its stone-grilled dishes, and I imagine there are probably visitors who come just for a day-trip meal without camping at all. Having the campsite and the restaurant run by the same operator might be an appealing point for anyone who wants to keep meal prep as simple as possible.

Honestly, I think the stone-grilled dishes would win me over before the campfire ever could. Being able to enjoy just the food without gathering up all the camping gear feels pretty welcoming for indoor types too.
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." Actual usability on-site probably varies depending on your device and exact location, but this is the rating I found within the scope of my research beforehand.
Given the location along the Arakawa River in a mountainous area, it's possible that connectivity varies from spot to spot. If you're planning to rely on a Rakuten Mobile connection for staying in touch or posting on social media while camping, it seems worth checking this rating ahead of time.

Hearing about a C rating makes me a little wary, but since it's the actual result from checking with the tool, I guess I just have to take it at face value. It felt like the kind of thing worth double-checking myself before heading out.
Nearby Sightseeing Spots, Hot Springs, and Roadside Rest Stops
Right near the facility are Masakado Falls and Sainenji Temple, both apparently reachable on foot. If you're traveling by car, Chichibu Shrine is about 15-20 minutes away, and Mitsumine Shrine is about 35-40 minutes away. If you'd like to enjoy a hot spring, Seibu-Chichibu Station Hot Spring Matsuri no Yu is roughly 15-20 minutes by car, and Chichibu Onsen Mangan no Yu is roughly 25-30 minutes.
There also seem to be several roadside rest stops nearby. Michi-no-Eki Arakawa is especially close at about 4-5 minutes by car, while Michi-no-Eki Chichibu, Michi-no-Eki Otaki Onsen (with the Yuyukan facility attached), and Michi-no-Eki Ryokami Onsen Yakushi no Yu are all roughly 15-20 minutes by car. Overall, it left the impression of an area where it's easy to plan out some nearby stops.
Wrapping Up
Pulling it all together, Okuchichibu Auto Campsite Suzukaen struck me as an auto campsite along the Arakawa River that combines sites with AC power with a restaurant serving stone-grilled dishes. Basic facilities like restrooms and a cooking area seem to be in place, but whether Wi-Fi is available remains unclear, and the official tool rated the Rakuten Mobile signal as a C, so it's probably worth planning with a bit of extra margin when it comes to connectivity. The stone-grilled dishes as a signature feature really stuck with me, so I'm noting this down as a place worth keeping in mind, restaurant included.
