I Looked Into Chichibu Sadamine Seiryu Camping Ground

In my Komorin Fantasy Travels, I've been steadily researching campsites, day-trip hot springs, and lodging facilities as an ongoing series. I've lost count of how many campsites in Saitama Prefecture I've looked into by now.

This time, the place that caught my attention was Chichibu Sadamine Seiryu Camping Ground. I decided to look into it because of its location along a clear stream and the fact that it's open year-round. As someone who's more of an indoor type, a campsite that stays open even in the cold season simply struck me as unusual, and that's what got me curious.

What Kind of Place Is Chichibu Sadamine Seiryu Camping Ground?

This is a campsite located in Sadamine, Chichibu City, and its clear-stream-side location seems to be its defining feature. By car, it's apparently about 30 minutes from the Hanazono Interchange on the Kan-etsu Expressway, or roughly 1 hour and 30 minutes total from central Tokyo. If you're taking the train, it seems to take about 30 minutes by bus from Seibu-Chichibu Station. Since I don't drive, having a bus-accessible route was reassuring information for me.

As for operating dates, general information seems to describe it as open year-round, but I couldn't find a page on the official website that clearly states the operating period. It might be a good idea to confirm regular closing days or any seasonal closures before booking.

Check-in and check-out times seem to vary by plan. For camping site stays, it looks like check-in runs from 12:00 to 17:00, with check-out by 10:00 the next day. Day-use visits, glamping, and old farmhouse stays apparently have different time slots, so it's probably worth confirming these when you book.

Hearing that it's open year-round, I got a little excited just imagining campfire camping in the cold season.

Site Layout and the Unusual System Where You Can't Reserve a Specific Plot

The site layout seems to consist of 24 shaded woodland plots, 6 open-sky plots, 2 family plots, and 2 power-equipped plots, for a total of 34 plots. The power-equipped plots reportedly come with fencing and allow pets, and at around 180 square meters each, they sound quite spacious.

The reservation system is a bit unusual. Apparently the official website states that plot reservations aren't accepted at all. In other words, you can book a date, but which specific plot you actually get seems to be decided on a first-come, first-served basis on the day. If you're hoping to snag a popular spot, it's probably worth aiming for an early check-in.

As for pricing, general searches turned up figures such as 2,000 yen per plot for site usage, 6,500 yen for power-equipped plots, and 16,000 yen for permanently set-up tent sites. However, the official campsite detail page itself doesn't seem to include a specific price table, and instead just links out to external booking sites, so it seems safest to double-check the latest prices when you actually book. Reservations are apparently possible both through the official website's system and through several partner booking sites. It also seems you can inquire about bookings by phone.

Checking the Facilities That Matter to Me as an Indoor Type

The restrooms are shared, with 2 flush toilets equipped with washlets, which felt like a pretty reassuring point for someone like me who's particular about restroom facilities. The coin-operated showers apparently cost 100 yen for 5 minutes, and the coin-operated hair dryers are also 100 yen for 5 minutes. There's reportedly a coin laundry on the premises too, which sounds handy for multi-night stays.

As for power, besides the 2 power-equipped auto sites, AC power rental is also apparently available on a reservation basis. Three wattage options are offered — 1,000W, 600W, and 400W — but the number available seems limited, so if you want to use one, it's probably best to reserve early.

Wi-Fi is available for glamping and old farmhouse stays, but the official Q&A apparently explicitly states that it's unstable at the tent sites. If you're planning to rely on internet access during a tent stay, this is something worth keeping in mind.

On top of that, the rental gear lineup is apparently extensive and well-suited to beginners, the shop stocks detailed camping supplies like gas canisters, white gas, and lantern oil, and fire-starting material is provided free of charge — all points that felt like welcome perks for beginners. Campfire stands can reportedly be used at every plot, the tap water is drinkable, and hot water is available even in winter, so it seems like you wouldn't run into much trouble even during cold-season visits. There's also apparently a quiet time set from 22:00 to 7:00, which sounds like a good environment for anyone who wants to spend a calm evening.

I Also Looked Into Nearby Hot Springs and Sightseeing Spots

The official website's nearby sightseeing information page seems to introduce several spots. As for hot springs, there's Araki Kosen, a long-established spring said to have been founded 200 years ago, located about 10 minutes away by car, where you can apparently enjoy an open-air bath and private baths. Other spots mentioned included a tour of Chichibu's well-known shrines such as Chichibu Shrine, Mitsumine Shrine, and Hodosan Shrine, as well as Hijiri Shrine, which is associated with the ancient Wado Kaichin coin, and the Nagatoro river boat rides and Nagatoro Fishing Center. Hitsujiyama Park, known for its cherry blossoms and moss phlox, and the winter-only Ashigakubo ice pillars were also introduced, but I couldn't find much specific information on travel times from the campsite, so aside from Araki Kosen, these remain unclear. If you plan to visit, it might be reassuring to look up the route to each destination beforehand.

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."

With a C rating, there's a chance the signal could be weak or unstable depending on the exact spot. Combined with the official note that Wi-Fi at the tent sites is unstable, if you're planning to rely solely on Rakuten Mobile for connectivity, it seems wise to picture ahead of time how you'd actually use it there. If you're worried about staying connected for work or other reasons, it might be reassuring to prepare things like a mobile battery just in case.

Honestly, hearing about the C rating gave me a little jolt. The clear-stream-side location might have something to do with it.

Wrapping Up

To sum it up again, my overall impression of Chichibu Sadamine Seiryu Camping Ground is that it's a campsite open year-round, with a wide range of beginner-friendly facilities including power sites, campfire options, and rental gear. Plots can be chosen but not reserved in advance, working instead on a first-come, first-served basis, which is an unusual system worth keeping in mind.

The Rakuten Mobile signal came back with a C rating, so if connectivity matters to you, it's probably worth checking your specific spot with the official tool beforehand. If you're concerned about it, you can check using the official Rakuten Mobile tool, so be sure to take a look before you head out.
