I Looked Into Izu iroha

On my blog, I've been steadily researching lodging facilities and campgrounds that seem accessible even without a car. Lately, beyond individual-oriented accommodations, I've also become curious about whole-building rental facilities for groups.

This time, I looked into a place called Izu iroha. I was curious about its scale—accommodating up to 40 people—along with information suggesting it comes equipped with a Finnish sauna and workation amenities, so I decided to dig into the details.

The Short Version

With the whole building rented out for up to 40 people, it seemed like a scale that would work well for company trips or group training camps, and it left the impression of having everything from a Finnish sauna to workation amenities.
As for the Rakuten Mobile signal, the official tool gave it a C rating.

I've summarized the details below.

A Whole-Building Rental Hotel That Seems Focused on Groups

Izu iroha appears to be a whole-building rental facility located in Ito City, Shizuoka Prefecture. Rather than being an individual-oriented hot spring inn, it apparently operates as a business specialized for groups of 20 or more, with a total of 8 rooms and capacity for up to 40 guests.

The room layout seems to consist of one premium suite over 80 square meters (with a bedroom, kitchen, and living room) plus seven standard rooms, each a Japanese-style room of about 10 tatami mats. It felt like a facility designed with company trips, trips among friends, and training camps in mind.

As for room rates, I couldn't find a fixed price list on the official website. It seems to be a custom-quote system where the estimate changes based on the number of guests, number of nights, meal style, and options. So if you're interested, it looks like a good idea to inquire through the group inquiry form, the official LINE account, or by phone.

Booking methods: Apparently you can book through the group-specific form, the regular inquiry form, the official LINE account, or by phone
Booking process: It seems to be a 4-step process—after submitting the form, a staff member checks availability and asks about your needs, then proposes a plan and estimated cost, before finalizing the booking
Dinner: There's an all-inclusive BBQ plan on the outdoor terrace, priced at 5,500 yen (tax included) per person

Since I usually spend time indoors by myself, just seeing the scale of a place that can host up to 40 people was a bit overwhelming. I'm not sure if I'll ever actually need a facility like this, but researching it was fun.

Checking Out the Finnish Sauna and Workation Amenities

The building apparently comes with a Finnish sauna, and outdoors you can also add a tent sauna as an option (a set for 4 people costs 16,500 yen, tax included). It felt like an amenity that would suit a training camp attended by sauna enthusiasts.

The building also seems to have plenty of amenities to keep you occupied into the night, including an outdoor BBQ space, a lounge with warm wooden decor, a drink bar serving draft beer and coffee, a karaoke and bar area, a mahjong room, and a space for campfires. I wasn't able to confirm the specific usage hours for each of these on the official website.

Another thing that caught my attention was the workation amenities. There appears to be a conference room that can accommodate up to 40 people, high-speed Wi-Fi, a large projector and screen, and whiteboards, along with an environment where you can choose your workspace—the lounge, a counter seat by the window, or the outdoor terrace. It gives the impression of being well-suited for training sessions or camp-style work.

That said, I couldn't confirm details such as in-room televisions, Wi-Fi, or refrigerators, the number and type of private baths, or whether washing machines and dryers are available, on the main official website text. If these matter to you, it seems like a good idea to inquire in advance.

I Also Looked Into Nearby Tourist Spots

The official website's nearby sightseeing page introduced natural spots like Mount Omuro and Jogasaki Coast with the Kadowaki Suspension Bridge, and Sakura no Sato, as well as experience-based facilities that seem enjoyable even on rainy days, such as the Izu Craft House and the Izu Teddy Bear Museum, plus popular spots like Izu Shaboten Zoo and Izu Granpal Park. However, I couldn't find specific distances or travel times from the facility listed, so it seems like a good idea to check separately if you're actually planning to visit.

Rakuten Mobile Signal Conditions

When I checked the location of this facility (the Yawatano area of Ito City) using Rakuten's official "My Area Connectivity Simulation" tool, the overall rating came back as a C.

If you're concerned about connectivity, this is the kind of rating worth knowing about beforehand. Given how well-equipped the place is with the Finnish sauna and workation amenities, it might be reassuring to check this as well.

Since the result was a C rating, I figured that if you're using Rakuten Mobile like me, it would be a good idea to also check the in-building Wi-Fi.

Wrapping Up

To sum up, Izu iroha left me with the impression of being a facility specialized for group use, offering a whole-building rental style that can accommodate up to 40 people, complete with a Finnish sauna and workation amenities. Since room rates aren't fixed and are custom-quoted based on the number of guests and details of your stay, if you're considering booking, it seems wise to inquire early.

As for the Rakuten Mobile signal, the official tool gave it a C rating. If this concerns you, you can check it yourself using Rakuten Mobile's official tool, so if you're thinking of using this place for a group trip or training camp, it might be reassuring to take a look beforehand.
