I Looked Into Hammer's Camp
2026-09-05

I've been gradually researching campgrounds around the Saitama area that seem accessible even for someone like me who doesn't own a car.
This time I looked into a facility called Hammer's Camp. It seems it used to be called Yakushi Park Campground, and when I found out it had been renewed, I got curious and decided to check out the details.
There's a day-trip hot spring called Yakushi no Yu at a roadside station in the Ryokami area nearby, which felt appealing since you could quickly wash off after camping.
The Rakuten Mobile signal came back as a C rating on the official tool, so it seems like connectivity might need a bit of caution.
I've summarized the details below.
What Kind of Place Is Hammer's Camp?
Hammer's Camp is apparently a campground located in the Ryokami area of Ogano Town, Chichibu District, Saitama Prefecture. It seems to have previously operated under the name Yakushi Park Campground, but it looks like it has since been renewed and renamed.
The operating season apparently runs from Golden Week through mid-November, with the facility closed from late November through April. It doesn't seem to be designed for winter use, so I felt it would be good to check the season in advance to avoid missing it.

Campgrounds that have changed their names always give me a bit of a thrill when researching them. Old information sometimes stays online even after it's outdated, so in cases like this, I try to prioritize sources that are closer to official.
Looking Into the Facilities and Reservation Process
This time I couldn't find an official website or official social media account, and I could only confirm information from third-party listing sites like Jalan and Iko-yo. Because of that, honestly, I wasn't able to find out details about facilities like the type of restrooms, whether there are powered sites, Wi-Fi, showers, cooking areas, or a shop through this research.
I also wasn't able to find clear information about pricing or check-in/check-out times. For reservations, it looks like phone bookings are listed as an option, but I couldn't confirm whether online reservations are also supported. If you're actually considering using this campground, contacting them directly seems like the surest way to check.
I know this means sharing information without knowing the facilities for sure, but since it seems to be a small facility with limited information available, I decided to just present it as-is rather than force any guesses.
Checking Out Nearby Hot Springs and Sightseeing Spots
I wasn't able to confirm whether there's a bath or shower on-site, but there's apparently a day-trip hot spring called Yakushi no Yu at a roadside station in the Ryokami area very close by, about a 1 to 3 minute drive away. Even if you're concerned about the campground's own facilities, having this day-trip hot spring nearby felt like it could work as a bathing option.
In addition, there's apparently day-trip bathing at a public lodge called Ryokami-so just a few minutes away by car, and within about a 5 to 15 minute drive, there are also sightseeing spots such as a historic site called the Koken Itto-ryu Henmi Dojo, a dahlia garden called Ryokami Sanroku Hana no Sato Dahlia Garden, and Marugami Falls, which has been selected as one of Japan's top 100 waterfalls. It seemed like it could be nice to venture out a bit before or after camping.
Rakuten Mobile Signal Conditions
When I checked this facility's location using the official "my Area Coverage Simulation" tool, the overall rating came back as "C".
I'm sharing this rating just as it came out from the official tool. The actual experience may vary depending on your device and the time period, so if you're planning to use this campground, it might be reassuring to check for yourself in advance.

A C rating is a bit of a concerning result. If it were me, I'd want to prepare things like offline map app features in advance just to be safe.
Wrapping Up
To sum it up, my impression was that Hammer's Camp is a small campground with limited facility information that seems like it could make good use of the nearby day-trip hot spring, Yakushi no Yu at the roadside station in the Ryokami area.
I couldn't find an official website, and I wasn't able to confirm details about facilities or pricing through this research, so if you're considering using this campground, calling to inquire directly seems like the most reliable option. The Rakuten Mobile signal came back as a C rating, so if that's a concern, it might be reassuring to check with the official tool yourself.
