I Looked Into Hotel Green Pearl Nasu

Not just campsites—I figured it's time to occasionally check out hot spring inns and hotels too, so as part of Komorin's Armchair Travel series, I've been gradually researching some "hokansu" (hotel + vacation) spots as well.

This time I looked into "Hotel Green Pearl Nasu." I got drawn in by the words "unfiltered natural hot spring" and "kaiseki cuisine," so I ended up researching this before even pulling out my camping gear.

An Inn on a Hill in Nasu-Yumoto, Known for Its Cloudy Waters

Hotel Green Pearl Nasu is apparently a hot spring inn located in the Nasu-Yumoto area of Nasu Town, Tochigi Prefecture. It reportedly draws from historic spring sources of Nasu Onsen—said to date back 1,380 years—and its signature feature seems to be a milky-white, hydrogen-sulfide-type simple sulfur spring. The building is said to carry the scent of sulfur throughout, which gives off that classic "this is what a real hot spring should feel like" vibe.

There's one large communal bath each for men and women, and apparently they swap between morning and evening. There's also an open-air bath attached, where you can reportedly enjoy stargazing at night. It seems private baths are available too, but I couldn't find detailed information about pricing or usage hours on the official site, so if you're planning to use one, it might be worth calling ahead to confirm.

Access is about 15 to 20 minutes by car from the Nasu Interchange on the Tohoku Expressway. Apparently it's recommended to search by the facility name rather than the address when using a car navigation system, and there was guidance suggesting you use the safari park's sign as a landmark. From JR Nasu-Shiobara Station, you can reportedly get there via a free shuttle bus (reservation required, limited runs), a local bus route, or a highway bus from Tokyo. Parking is free with 30 spaces and apparently no reservation needed.

I technically have a driver's license, but I'm basically a paper driver, so knowing there's a shuttle bus and highway bus option was reassuring. If you're driving yourself, it seems safer to double-check how to search on your navigation system beforehand.

Guest Rooms, Kaiseki Cuisine, and In-House Facilities for Indoor Types

There are apparently 21 guest rooms in total, across 5 different types. Besides a 12-tatami-mat "spacious Japanese-style room," a Western-style twin room, and a barrier-free Western-style room, there's also a "room with open-air bath (Nasu hot spring)" that reportedly opened newly in July 2024. Rooms come equipped with Wi-Fi, TV, a fridge, and a washlet toilet, and it seems yukata robes and amenities are available freely from an "amenity bar" at the front desk rather than being placed in the rooms.

Dinner is served from 6:00 PM to 8:00 PM, apparently in the dining hall as a seasonal Japanese-style kaiseki course. The menu is said to be refreshed every two months, reportedly featuring highland vegetables and dairy products grown at the foot of the Nasu mountain range. Breakfast runs from 7:30 AM to 9:00 AM and appears to be a Japanese-style breakfast served in a basket. I couldn't confirm on the official site whether there are special plans like shabu-shabu or sukiyaki.

Inside the hotel there's a lobby lounge with a round fireplace, and it seems espresso from an espresso machine is offered for free. With facilities like ping pong, a karaoke box (2,000 yen per hour), a mahjong room with 4 automatic mahjong tables, and a free laundry corner, it looks like there's plenty to do even for indoor types. Wi-Fi is reportedly available throughout the entire building and in every room.

Checking Out Nearby Sightseeing Spots Too

According to the official site's page on nearby sightseeing spots, several attractions are introduced with the assumption that you'll be traveling by car—Nasu Safari Park and the Asian Old Bazaar are about 6 minutes away, and Nasu Highland Park is about 9 minutes away. The Nasu Ropeway and Mt. Chausu are apparently just under 20 minutes by car, while Nasu Animal Kingdom and Nasu Garden Outlet take over 20 minutes. Interestingly, the "Lovers' Sanctuary" spot was listed as about 90 minutes on the official site, which is quite a bit longer than the other spots, so it might be worth double-checking if you actually plan to visit. Specific restaurant names weren't listed on the official site.

Rakuten Mobile Signal Conditions

I tried checking this facility's location using Rakuten Mobile's official My Area Network Simulation tool, but this time no result showed up, and I wasn't able to get a reading. I tried a few times and got the same result, so at this point I think it's best to treat this as "unknown."

To be upfront about it, this research didn't turn up any clear information about the signal conditions. If you're actually considering staying here, it might be a good idea to check with your own device and carrier setup before you head out.

I use Rakuten Mobile myself, so situations like this leave me a little unsettled. I don't think a missing reading necessarily means the signal is bad, so if you're concerned, it seems like the only way to know for sure is to try it out on site.

Wrapping Up

To sum it all up again, my impression of Hotel Green Pearl Nasu was of a hot spring inn where you can relax and enjoy milky-white unfiltered sulfur spring water along with kaiseki cuisine that changes with the seasons. With a wide range of room types, including options like the room with an open-air bath, it also seems well-suited to indoor types who'd rather relax in their room. The building offers plenty of ways to spend your time too, with a lounge, mahjong room, and karaoke box, making it feel like a comfortable place to stay even on a rainy day.

That said, I wasn't able to confirm the Rakuten Mobile signal conditions during this research. If that matters to you, you can check using Rakuten Mobile's official tool, so it might be worth taking a look before you book your stay.
