I Looked Into Ajiro Kanko Hotel

Not just campsites—on this blog I've been continuing to look into hot spring inns that could work for those "let's skip camping and do a hokans day instead" kind of days, focusing on whether you can get there without a car.

This time I looked into Ajiro Kanko Hotel, located in Atami City, Shizuoka Prefecture. The idea of a purely Japanese-style inn with tatami flooring throughout the building and its own hot spring source flowing continuously really caught my attention, and as an indoor type myself, I couldn't help but want to dig into the details.

The Short Version

All 15 rooms have tatami flooring, and the inn keeps its own hot spring source flowing continuously 24 hours a day—it seemed like a hot spring inn that really puts its Japanese atmosphere front and center.
The Rakuten Mobile signal came back as a "C" rating according to the official tool, so I'll be upfront about that.

I've summarized the details below.

I Looked Into the Basic Details of This Purely Japanese-Style Hot Spring Inn

Apparently at Ajiro Kanko Hotel, everything from the entrance to the hallways to the guest rooms is covered in tatami flooring, and looking at the official website, I got the impression that the whole building really emphasizes a Japanese aesthetic. The compact scale of just 15 rooms also seems to contribute to a calm, relaxing atmosphere.

As for the baths, apparently the inn's own hot spring source is used on a continuous 24-hour flow basis for the large communal bath, the reservable private open-air bath, and the in-room open-air baths as well. There also seem to be rooms with open-air baths offering ocean views, so being able to enjoy both the scenery and the hot water without leaving your room was a point that caught my interest as an indoor type.

For meals, it seems the inn serves dishes made with seafood caught locally in Ajiro. That said, I couldn't confirm the exact format—whether meals are served in your room or in a dining hall—since neither the official website nor Rakuten Travel had any clear information about it.

Pets: Small dogs and cats (6kg or under) can apparently stay for free, though you need to bring their food and bedding yourself
There was also mention of a photo spot set up specifically for pets
Pricing: I couldn't find specific rates listed, but there was a note saying that booking through the official website saves you 1,000 yen per person compared to other travel sites
Check-in/check-out: According to Rakuten Travel, check-in is from 2:00 PM to 6:00 PM and check-out is at 11:00 AM, though this may vary depending on the plan

Lounging around on tatami mats while soaking in a continuously flowing hot spring source sounds like a combination that would really hit home for someone like me who's an indoor type.

Checking Access and Booking Methods

As for access, apparently you'd take the JR line to Atami Station, transfer to the Ito Line, ride it to Ajiro Station, and then it's about a 4-minute walk from there. There doesn't seem to be a shuttle service available, so it's probably best to plan around traveling by train. For someone like me who barely ever drives, the fact that you can get to the nearest station by train was pretty reassuring information.

That said, for those heading there by car, there's apparently a paid parking lot with space for 12 vehicles (700 yen, tax excluded). Payment methods seem to include cash, credit card, and PayPay.

For booking, it seems the standard method is through the reservation page on the official website, though some plans—like a ladies' plan—are apparently only accepted via Instagram direct messages. If there's a specific plan you're interested in, it's probably worth checking both the official website and Instagram so you don't miss anything. Booking by phone is also apparently available.

Rakuten Mobile Signal Conditions

When I checked the location of Ajiro Kanko Hotel using the official "My Area Network Simulation" tool, the overall rating came back as "C."

I was also curious about how far the Wi-Fi coverage extends throughout the building, but I couldn't confirm any details on that either, since neither the official website nor Rakuten Travel had specific information about it. If you're planning to rely mainly on Rakuten Mobile for connectivity during your stay, it might be worth preparing for that in advance.

Seeing that "C" rating made my shoulders drop a little too. That said, if you're just planning to relax in a tatami room, maybe it's fine to just forget about connectivity for a while.

Wrapping Up

To sum it all up, Ajiro Kanko Hotel left me with the impression of being a hot spring inn with a striking, purely Japanese-style design—tatami flooring throughout the building and its own hot spring source flowing continuously 24 hours a day. Between the ocean-view rooms with open-air baths, the meals made with local seafood, and the fact that pets are allowed to stay, it feels like a great fit for anyone who wants to slowly soak in a Japanese atmosphere.

Access is about a 4-minute walk from Ajiro Station, which makes it feel manageable even by train—a reassuring point for someone like me who barely drives. On the other hand, the Rakuten Mobile signal came back as a "C" rating, so if connectivity matters to you, it's probably worth checking the official tool yourself before booking your stay.
