I Looked Into Izu Uminomori Smile Campground

This blog is all about looking into campgrounds and day-trip hot springs one at a time, and this time I found another new candidate to check out. I've been continuing to look at campgrounds located close to the sea.

This time, the one that caught my attention was "Izu Uminomori Smile Campground." Beyond the fact that its name includes "sea forest," I was intrigued by the combination of being a campground with a natural hot spring just 30 seconds away on foot, so I decided to sort through the information for now.

The Short Version

It seems to be quite a luxurious combination — a campground located just 80m from the sea, with a natural hot spring only 30 seconds away on foot.
That said, the Rakuten Mobile signal came back with a C rating, so I'll be upfront about that.

I've put together the details below.

What Is Izu Uminomori Smile Campground Like?

It's a campground and auto-camping facility located in Fumoto, Ito City, Shizuoka Prefecture, apparently operated under the name "IZUMI RESORT." It sits on a bluff 25 meters above sea level, and apparently it's only about 80 meters to the sea. It's about a 15-minute walk from Izu Kyuko Line's Futo Station, and parking is available too, apparently.

Check-in is at 15:00 and check-out at 11:00, but it seems you can consult about early check-in or extending your stay. Closed days are irregular, so it seems worth checking before you visit.

The pricing structure is a bit distinctive, seeming to combine the following elements.

Facility usage fee: 600 yen for adults, 300 yen for elementary school students, 200 yen for preschoolers (this appears to include hot spring access)
Basic camping space (6.4m x 6.4m): 6,000 yen on weekdays, 7,500 yen on Saturdays or during busy seasons
Glamping tent stay + one space set (with hot spring): 21,500–23,500 yen for two adults, plus 3,300 yen per additional person
Camper van stay + one space set (with hot spring): 21,500–23,500 yen for two adults
Tatami lounge + space plan: starting at 19,500 yen for two people
BBQ patio (reservation required): 3,800 yen for up to 4 people, 5,800 yen for 5–8 people

Reservations are basically handled through the official LINE account, and it seems to be a three-step process: check the guidelines, inquire about availability, and then finalize the reservation. The timing for when reservations open varies by plan — glamping, camper van, and full-facility rentals open 6 months in advance, 1–2 spaces open 3 months in advance, and a single space opens 1 month in advance. If you're in a hurry, it seems you can also make a reservation by phone.

I thought that having some plans open for reservations sooner and others later could catch people off guard if they're not careful. If there's a specific date you have in mind, it seems worth checking early.

A Range of Hot-Spring-Included Stay Options

One of the features of this campground seems to be the wide variety of ways to stay. Beyond tent camping, there are options that seem approachable even for camping beginners, such as rental glamping tents (with air conditioning and a kotatsu), retro-renovated camper vans (with air conditioning), and tatami lounges (with TV, air conditioning, and carefully chosen bedding).

On the facilities side, I was able to confirm the following.

Natural hot spring, apparently about 30 seconds on foot from the facility — you can also use just the hot spring or just the shower on their own (hot spring + shower is 600 yen for adults, 300 yen for elementary school students, 200 yen for preschoolers; shower only is 500 yen for adults, 250 yen for elementary school students)
BBQ patio: apparently covered with a roof and fully equipped with cooking utensils
Restrooms, wash areas, laundry, vending machines, and a smoking area are all available, and it seems staff are on-site
Rental items (per day): power supply (100V) 600 yen, wood stove 600 yen, trash disposal 300 yen, chair 400 yen, tarp 1,600 yen, fan (large) 1,500 yen / (small) 1,000 yen, extension cord 500 yen, among other detailed offerings

Pets seem to be allowed, but there's a condition that they can't be brought into the rental camper vans or glamping tents, so if you're considering bringing a pet, it seems worth checking in advance. Also, quiet manners are required after 21:30, and large bonfires are apparently explicitly listed as prohibited.

Rakuten Mobile Signal Conditions

When I checked this facility's location using the official My Area Network Simulation tool, the overall rating came back as "C."

Given this rating, it seems worth checking in advance depending on how you plan to use your connection. The bluff location close to the sea might have something to do with it, but here I'll just summarize what I found using the official tool as it is. If you're planning on doing remote work or watching videos at the campground, it might be reassuring to prepare with this result in mind.

Honestly, when I saw the C rating, I felt a bit disappointed. Being close to the sea with what's probably a nice view might mean the signal takes a bit of a hit. If it were me, I think I'd bring a mobile Wi-Fi backup just in case.

Access and the Surrounding Area

It's about a 15-minute walk from Izu Kyuko Line's Futo Station, and as someone who doesn't drive, being within walking distance of the station was welcome information. Parking is also available, so it seems like a facility that accommodates visitors arriving by car too.

Nearby there seem to be sightseeing spots like Izu Shaboten Zoo, Mt. Omuro, and Jogasaki Coast, but the official website didn't list specific distances or travel times from the facility, so I wasn't able to confirm those details. Since it's apparently only 80 meters to the sea, it also seems like the kind of place where you could take a stroll down to the shore.

Wrapping Up

Looking back over everything, my impression of Izu Uminomori Smile Campground is that it's a campground characterized by its location close to the sea, a natural hot spring just 30 seconds away on foot, and a wide range of stay options including glamping and camper vans. It seems well-suited for people who want to enjoy nature along with the facilities, rather than sticking strictly to tent camping.

On the other hand, the Rakuten Mobile signal came back with a C rating, so if connectivity matters to you, it seems worth checking in advance. You can check this yourself using Rakuten Mobile's official tool, so it might be worth adding to your pre-visit checklist.
