I Looked Into Bukou Campground
2026-08-28

I've been researching and writing up campgrounds that even someone like me, who doesn't drive, could realistically get to. This time I looked into another one and wanted to organize what I found.
This time I looked into "Bukou Campground," located in Yokoze Town, Saitama Prefecture. I came across mention that there's a day-use hot spring facility right next to the campground, and being able to jump straight into a bath after tent camping sounded pretty appealing to someone as indoorsy as me, so I decided to gather some information.
The biggest appeal to me was that there's a day-use hot spring right on the property, so you can freshen up in the bath right after camping.
As for Rakuten Mobile signal, the official tool didn't display a result at all, so it remains unknown.
I've laid out the details below.
What Kind of Place Is Bukou Campground?
Bukou Campground is apparently a campground attached to a day-use hot spring facility called Chichibu Yumoto Bukou Onsen, located in Yokoze Town, Chichibu District, Saitama Prefecture. It looks like the company that runs the hot spring facility also runs the campground as a single operation, and on the official site it's listed as "Chichibu Yumoto Bukou Onsen Campground." The name "Bukou Campground" seems to be more of a nickname used on various campsite search sites.
It's apparently open year-round, though it may close due to weather. Check-in seems to start at 11 AM, with check-out by 10 AM the following day. For car camping, the rate appears to be 5,500 yen (tax included) per night with a car, covering up to 4 people plus one tent and one tarp, or 4,400 yen (tax included) without a car, with extra charges for additional people or vehicles. There also seem to be plans for solo camping, priced at 3,300 yen if you bring a car or 2,200 yen if you arrive on foot. Day camping without an overnight stay also seems to be available.
Reservations can apparently be made online through a camping reservation site called Nap, or by phone. I couldn't find clear official information about when reservations open, so that part remains unclear.

A campground that's integrated with a hot spring facility feels like a quiet reassurance for someone like me who's more of an indoor person. Even if camping itself feels like a hurdle, knowing there's a hot spring waiting at the end makes me feel like I could push through it.
Things I Noticed About the Facilities
As for the facilities, the official site's main content is built with JavaScript so I couldn't check the details directly, so I've put this together based on tourism association sites and reservation sites instead. The restrooms are apparently flush toilets, and some sources mention Western-style toilets with heated bidet seats. It also seems you can use the restrooms at the adjacent hot spring facility, which is reassuring.
There don't appear to be any powered campsites, and there's apparently no dedicated Wi-Fi within the campground either. There are cooking areas, but apparently no hot water is available there, so you might need to prepare a bit more during colder months. There doesn't seem to be a standalone shower room at the campground itself, but you can use the adjacent Chichibu Yumoto Bukou Onsen, and there's apparently a discount for campers, so bathing options seem quite convenient.
The shop apparently sells firewood and charcoal, and also offers rentals of tents and full barbecue equipment sets. For someone like me who isn't confident about bringing a full set of gear, relying on rentals could really lighten the burden of preparation. I couldn't find clear official information about accessibility, so that remains unknown.
Rakuten Mobile Signal Conditions
When I entered this facility's location into the official My Area Connectivity Simulator, no connectivity judgment was shown at all — instead it displayed something along the lines of "currently under temporary maintenance." It seems this kind of message can appear when there isn't enough data for the target area, so I wasn't able to get an overall assessment this time. Because of that, I'm treating the signal conditions in this article as "unknown." I've summarized what I was able to confirm as-is.

I think this is the first time I've seen a case where no judgment came up at all. It's probably somewhat unavoidable in mountainous areas, but this is really something you can only find out by actually going there.
Nearby Spots Worth Visiting
Chichibu Yumoto Bukou Onsen is right next to the campground, so it seems to be about a 1 to 3 minute walk away. By car, it's apparently about 10 minutes to Matsuri no Yu, the hot spring near Seibu-Chichibu Station, and about 5 to 10 minutes to Hitsujiyama Park, known for its shibazakura flowers. The Terasaka Tanada rice terraces and Chichibu Shrine also seem to be within about 10 minutes by car, so it looks like a location where you could take a short break from camping to enjoy some sightseeing. The roadside stations Kaju Koen Ashigakubo and Chichibu also each seem to be about 10 minutes away by car, so finding a place to pick up supplies looks fairly easy too.
Wrapping Up
Putting it all together, my impression of Bukou Campground is that its biggest strength is the location, letting you head straight into the adjacent day-use hot spring right after camping. Facilities like power outlets and Wi-Fi seem fairly minimal, but with a hot spring, a shop, and rental gear all available, it feels like a campground that even indoorsy people could reasonably consider. Since the official Rakuten Mobile tool couldn't produce a judgment for the signal conditions, it might be worth checking a location close to your actual destination beforehand for peace of mind. If you're curious, you can check it yourself using the official Rakuten Mobile tool, so it's probably worth a quick look before you head out.
