I Looked Into Nemoto Marine Camp Site

This blog keeps digging into camp sites, day-trip hot springs, and lodging facilities, but this time I wanted to cover something with a bit more of a seasonal feel. As I've been going through a series of seaside camp sites, I realized I hadn't yet covered the type where you can pitch a tent directly on the sand, so I got curious and looked into one.

This time I looked into "Nemoto Marine Camp Site." It's located next to a beach in Minamiboso City, Chiba Prefecture, and seems to feature a pretty open, spacious location.

What's This Beach Site Facing the Pacific Ocean Actually Like?

Apparently, Nemoto Marine Camp Site is located next to Nemoto Beach in Shirahama-cho, Minamiboso City, Chiba Prefecture. The grounds span roughly one hectare, and it's said to be able to accommodate over 400 tents, making it one of the larger beach camp sites in Chiba Prefecture from what I found.

Since you can pitch your tent directly on the sand, the appeal seems to be that you can enjoy swimming, BBQ, and marine sports all in one place. I came across information suggesting the waves are calm with a lot of shallow water, making it easy for families with kids to use, but please take that as just information I found rather than something I can confirm firsthand. There was also mention that with few streetlights around, you might get a great view of the stars.

That said, there seem to be some things to watch out for that come with a beach site. Since regular tent pegs won't go into the sand, apparently the reception desk lends out sandbags, and I also found information saying open fires are prohibited. With nothing to block the sun and a location prone to strong winds, it seems like a good idea to prepare properly with a tarp and sun protection.

Pitching a tent directly on the sand feels like a pretty unusual sight to me. As someone who's more of an indoor type, I feel like I'd need to start by picturing how I'd deal with all that sand.

Facilities That Catch My Eye as an Indoor Beginner

I couldn't find a detailed facilities page on the official website—just a handful of photos on the site map. So the following is based on third-party information, and it's probably a good idea to check the latest details before actually visiting.

• Restrooms: There's information suggesting flush toilets are available, and it seems portable toilets are also set up on the west side sites
• Cooking area: There's a cooking building, and apparently there are quite a few of them and they're kept fairly clean
• Showers: It seems hot water showers cost a fee (around 100 yen per use), while cold water showers may be free
• Powered sites: Apparently these aren't basically available
• Wi-Fi: I couldn't find any information, so whether it's available remains unclear

Since power apparently isn't basically available, it might be reassuring to bring extra portable battery packs. I also found information suggesting pets are allowed, but since I couldn't find an official notice about this either, it's probably safest to check before your visit.

What I Found Out About Operating Season, Pricing, and Access

The official website doesn't clearly state the operating season, but apparently it typically runs from mid-July to around August 20th, matching the opening period of Nemoto Beach. According to a news update on the official website, the 2026 season ended operations on August 16th, so if you're thinking of visiting next season, it seems worth checking the opening dates in advance. The fact that this is a summer-only facility feels like a particularly important point to keep in mind, depending on when you're reading this.

Pricing isn't posted on the official website, but according to third-party sources, a family camping trip (2 adults, 2 children, 1 car) runs around 2,400 yen, while solo camping with a car runs around 1,700 yen. Please treat these as reference figures only—it's probably safest to confirm the actual pricing by contacting the facility directly. As for reservations, I couldn't find a reservation form on the official website, though I did find information suggesting phone reservations are possible—but that also seems worth double-checking.

For access, the official website mentions that by train, you can take a JR Bus Kanto bus from JR Uchibo Line's Tateyama Station and get off at the "Nishi-Nemoto" bus stop, about a 5-minute walk from there. By car, it's about 15km from the Tateyama IC on the Tateyama Expressway. Since this facility is located in the Shirahama-cho area of Minamiboso City, bus frequency might not be very high, so checking the timetable in advance seems like a good idea for peace of mind.

Since I don't drive, I'd probably be taking the bus, but since the frequency seems limited, I feel like I'd need to plan things out carefully while staring at the timetable.

Checking Out Nearby Sightseeing and Hot Spring Spots

Within walking distance is Shirahama Flower Park, apparently about a 13-minute walk away. Hotel Jungle Palace, which offers day-trip bathing, is also about 16 minutes away, so it could be a good option if you want to soak in a bath after camping. Going a bit further, you can apparently also see Nojimazaki Lighthouse and Byobu Rock, known for its unusual rock formations and tide pools near Nemoto Beach.

For grocery shopping, there's apparently a supermarket about a 5-minute drive away, and roadside stations like Michi-no-Eki Shirahama Nojimazaki and Michi-no-Eki Minamibo Paradise also seem reasonably accessible if you're driving. However, if you don't drive like me, it might be safer to stock up on food beforehand.

Rakuten Mobile Signal Conditions

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

Even though it's an open, seaside location, this was the result within the scope of what I checked this time. If you're a Rakuten Mobile user considering a visit to this facility, it might be reassuring to keep this result in mind and prepare to be comfortable offline if needed.

Since I also use Rakuten Mobile, that C rating was a bit concerning to see. It made me realize once again that just because a place seems close to the ocean doesn't mean you can assume the signal will be good.

Wrapping Up

Looking back over everything, my overall impression of Nemoto Marine Camp Site is that it's a camp site whose main appeal is the open location where you can pitch a tent directly on the beach facing the Pacific Ocean. Being able to enjoy swimming and BBQ together seems perfect for making summer memories, but it's probably worth confirming in advance that operations are limited to summer, and that you'll need to plan your gear around the quirks of a beach site.

As for the Rakuten Mobile signal, it came out as a "C" rating, so if you're thinking about using this facility, it might be reassuring to check for yourself using the official tool as well.
