Who's writing this

I'm Hoshi. I own a barrel sauna on family land in the Japanese countryside — a 25-minute drive from my house, surrounded by forest and vegetable fields. I've had it since April 2023.

That's the short version. Here's why it might be worth your time.

Two sauna hats hanging in the barrel — one from Elamus Spa in Estonia, one from a bathhouse in Kyoto — Two sauna hats hang in the barrel — one from Elamus Spa in Estonia, one from Rooma Plaza in Kyoto. Mine and my wife's.

It started with a comic book

Before Japan's sauna boom went mainstream, a friend recommended a manga called Sadō by Katsuki Tanaka. I read it, and it taught me things nobody had ever told me about a room I'd been sitting in wrong my whole life:

That the sauna is only step one. You go into cold water afterward.
That in the cold bath you stay still, and a thin, silky layer of warmed water forms around your skin — Japanese sauna people call it the hagoromo, the "feather robe." Move, and you break it. Stay still, and it's bliss.
That afterward you sit outside and do nothing, your head goes quiet and floaty, and something arrives that the language calls totonou — "to be put in order."

Armed with that, in 2018 I walked into Hakusan-yu, a public bathhouse in Kyoto's Rokujō district, and ran the sequence properly for the first time.

It was exactly as described. Every part of it. I had been going to saunas for years without knowing how to use one, and in one afternoon a comic book and an old Kyoto bathhouse handed me the best hour I'd had in a long time.

Since then I've chased it: across Japan's bathhouses, to Finland and Estonia twice, and eventually into my own family's field.

Then I spent five years inside the sauna business

Full disclosure, because it matters: for about five years I've worked as a contractor with totonoü, a Japanese sauna distributor — since roughly their founding. I helped build their site and their behind-the-scenes systems, and these days I help with some business development and hiring. I also bought my own sauna through them.

I earn nothing from their sales. This site doesn't link to them, promote them, or make money from them.

I'm telling you this for two reasons. First, hiding it would be dishonest, and honesty is the only thing this site has to sell. Second, it's the reason I know what I know: I've watched how saunas get imported, sold, installed, and lived with — from the inside, for half a decade — and then I became a customer myself.

Most sauna blogs are written by people who own a sauna, or by people who sell saunas. I've been both, and I'm being straight with you about which parts are which.

What I actually own

Sauna: Tesler barrel, 4-person, Estonian-built (~$10,000)
Heater: Tylö Pure 8kW — significantly oversized for this barrel, acquired secondhand from a Japanese sauna facility. This matters enormously, and I explain why in nearly every article on this site
Cold plunge: a cast-iron Japanese goemon tub, tap water only, no chiller (~$1,700)
Rest: a zero-gravity chair, and the wind coming across the fields
Installed by: a crew that does nothing but sauna construction — five people, one day
Hidden costs nobody warned me about: a new power line (yes, an actual pole), foundation work, drainage

Three years in: roughly 50–70 sessions, about 40 guests, one dead LED light, one repaint done by hand with my kids, and — in July 2026 — one wasp nest that I'd previously and confidently written could never happen. I left that mistake in the article rather than editing it away.

What this site is for

There's a specific person I'm writing for: someone in the US, standing at the edge of a $5,000–10,000 decision, who has read a hundred product pages and still doesn't know what it's actually like to own one of these.

I can't tell you what to buy. I can tell you:

What it really costs, including the bills after the purchase — running costs
What breaks and what doesn't, over three years — problems
Why the Finns think my sauna is wrong, and why they're mostly right — the case against my own barrel
And what Japanese sauna culture knows that hasn't made it into English yet — totonou, outdoor air bathing, and the three-set ritual

Everything here is measured, photographed, or lived. When I'm guessing, I say so. When I'm wrong, I correct it in public.

The best session I've had

Three friends. A full moon. We ran our sets, plunged, and lay out under the open sky. Afterward we stayed in the barrel on residual heat — a ritual we call yonetsu, the afterglow — eating smoked food and talking for hours.

Nobody was performing. Nobody was trying to impress anyone. We were, briefly and completely, satisfied with our lives exactly as they were.

That's what I bought. The heater and the cedar were just the delivery mechanism.

Two sauna hats hang in my barrel: one my wife brought back from Elamus Spa in Estonia, one from a bathhouse in Kyoto. That's more or less the whole story of this site — a Japanese ritual, a Baltic sauna, and a family in a field somewhere in between.

Kiitos. Aitäh. And thank you for reading.
