I Looked Into Treehouse Village Odagiri Garden

On this blog, I'm gradually researching and writing up campgrounds, cottages, and lodges from around the country that even I, without a car, might be able to get to.

This time I looked into Treehouse Village Odagiri Garden, located in the Nasu Highlands in Tochigi Prefecture. I came across a story about the owner designing and building the treehouses themselves, and that alone made me curious about what kind of place this is.

What Kind of Place Is Treehouse Village Odagiri Garden?

This is a campground located in Nasu Town, Nasu District, Tochigi Prefecture, apparently open year-round with no regular closing days. The biggest feature is the treehouses that the owner, Mr. Odagiri, reportedly designed and built by hand himself. Based on the pricing table on the official site, there appear to be 22 of them, though some feature articles mention "about 25," so the exact number seems to vary a bit depending on the source. If one person really did build that many on their own, this must be a place built on some serious passion — that's the impression I got while researching.

The concept is apparently a "treehouse campground where you can become Tom Sawyer," and I read that at night, a sky full of stars combined with the lights of the treehouses creates a dreamlike scene. Aside from the treehouses, there are also 2 bungalows, each seemingly meant for around 4 to 5 people. Tent sites and tarp sites are also available, so it seems like there's flexibility for those who don't necessarily want to stay up in a tree.

Here's a rough guide to pricing (since the official site archive I referenced dates from around 2020, it's probably a good idea to check the latest rates before actually booking).

• Treehouse: 15,000 yen per unit per night (22 units)
• Bungalow: 15,000 yen per unit per night (2 units)
• Tent site: 5,000 yen per group per night
• Tarp site: 1,000 yen per tarp per night
• Firewood: 500 to 1,000 yen per bundle (one wheelbarrow load)
• Rentals: sleeping bag (summer type) and hammock, 500 yen each per day; futon or blanket, 200 yen each (self-reported/honor system)

There's apparently no online booking form — reservations are only accepted by phone (reception hours are said to be 9:00 AM to 9:00 PM, open every day).

I'm honestly amazed just imagining the scale of one person handbuilding more than 22 treehouses. Just sleeping up in the trees alone sounds like it'd feel like living out a secret hideout fantasy.

Facility Details That Matter to Someone Like Me Who's More of an Indoor Type

Each treehouse apparently has electricity (AC power/outlets), so charging a phone on-site shouldn't be a problem. That said, some feature articles mention that the wooden construction tends to get quite cold at night, and I wasn't able to confirm from the official site archive just how much heating equipment is actually provided. Depending on the season, it might be reassuring to bring solid cold-weather gear.

On the other hand, there's apparently no Wi-Fi on-site. Shared flush toilets with washlets, a cooking building/cooking area, and trash disposal all seem to be provided, but there's no bathroom or shower facility on-site, so if you want to wash up, it looks like you'd need to use a nearby day-trip hot spring. Sleeping bags and food basically need to be brought yourself, and it seems like only a limited selection of rental items — sleeping bags, hammocks, and so on — is available.

On the grounds, besides a firewood storage area, there are apparently also handmade play equipment and an obstacle-course-style athletic area, and both open fires and bringing pets seem to be allowed. Kitchen and barbecue facilities appear to be freely usable by guests, so meal prep itself might actually be fairly easy here.

Nearby Places to Visit

According to the official site, it's about 29 minutes by car from Nasu Kogen Smart IC, about 34 minutes from Nasu IC, and about 38 minutes from JR Kuroiso Station, so this looks like a place that basically requires a car rather than public transportation. Nearby, there are roadside rest stops such as Nasu Kogen Yuai no Mori and Tosando Ionu, as well as day-trip bathing spots like Nakafujiya Ryokan and Pyramid Genki Onsen. Sightseeing spots such as Nasu Senbonmatsu Farm, Sesshoseki, Nasu Onsen Shrine, the Tsutsuji Suspension Bridge, and Otome Falls also seem to be in the general area, though I wasn't able to confirm the exact travel time to each one in this research.

Rakuten Mobile Signal Conditions

When I checked this facility's location using the official "My Area Coverage Simulation" tool, no result was displayed at all — instead it just showed a message saying "currently undergoing temporary maintenance." It seems this kind of message can appear when the address data for a location hasn't yet been reflected in the tool.

So for this case, I can't say the signal is either "good" or "insufficient" — my conclusion is that it remains unknown. Given that these are treehouses surrounded by trees, there's a chance the signal might not reach well, but I wasn't able to actually confirm that.

Honestly, having no result come up was a bit anticlimactic, but sharing results exactly as they are — even when they're inconclusive — is my policy, so I'm writing it here just as it is.

Wrapping Up

To sum up, Treehouse Village Odagiri Garden left me with the impression of being a campground with more than 20 handmade treehouses lined up, offering a secret-hideout kind of atmosphere unique to the Nasu Highlands. Electricity is available, but there's no Wi-Fi and no bathroom on-site, so it seems like a fairly simple, back-to-basics setup facility-wise. Since the official Rakuten Mobile tool wasn't able to give a result either, if you're planning to use your phone there, it's probably worth checking the official Rakuten Mobile tool yourself beforehand.
