That day, I wasn’t just buried in sand—I was gently, hilariously excavated from fear. Because sometimes, healing doesn’t come wrapped in essential oils or scented candles. Sometimes, it arrives in the form of soft sand, unexpected silence, and the courage to strip down—emotionally, culturally, and yes, completely—and still choose to smile through it.

They say travel broadens the mind. In Ibusuki, it also strips you naked—literally.

I signed up for a sand bath expecting Zen vibes and maybe a cup of green tea. Instead, I found myself in a locker room full of confident nudity, clutching a tiny hand towel like a fool and praying my bra wouldn’t explode from sheer tension. I thought I was ready for Japan’s famous hot sand bath—until I realized it required me to remove my underwear in front of strangers and pretend that everything, including my dignity, was totally fine. Who knew wellness came with this much emotional cardio?

Calm down, folks—no NSFW photos here, promise! 😅 This story is for the modest, the mildly traumatized, and the overly imaginative, like myself, who somehow survived being buried alive… in steamy volcanic sand… with a side of unsolicited nudity.

It was a cool spring morning when we rolled into Ibusuki, a peaceful seaside city tucked at the southern tip of Kagoshima Prefecture, Japan. The kind of town that feels like a whisper—quiet, slow, polite. It hugs the coast of Kagoshima Bay, breathing in steam from natural geothermal springs and exhaling calm.

But within this whisper was something wildly unexpected: a spa experience called Sunamushi Onsen, or Hot Sand Bathing, where you’re buried alive—voluntarily—

…and oh yes, nearly naked—just a yukata between you and the world.

I’d read about it, of course. The volcanic sands heated to around 50–55°C, detoxifying your body and gently roasting you like a shy human sweet potato. They say it improves circulation and oxygen levels. They say it calms you.

Our destination was the most famous sand bathing facility in town— Ibusuki Sunamushi Onsen Natural Sand Bath “Saraku”, located in the Yukohama district, right along the scenic shoreline. With views of Kaimondake Volcano in the distance and the gentle sea breeze brushing past the windows, Saraku is the place to experience this centuries-old therapy that’s truly unique to Ibusuki. While other onsen towns may have baths and steam, only Ibusuki boasts this rare combination of volcanic heat and black coastal sand.

When you arrive, everything feels neat and organized. You get your ticket at the registration counter, where the friendly staff hand you a cotton yukata (robe), a small towel—more like a hand towel, really—and a locker key. You’ll look into a gender-separated changing room…

What they don’t say is how unnerving it feels to walk into a room where everyone is naked and okay with it—except you.

Prelude to Panic: The Changing Room from Hell

Let me paint you a picture: I walked into the women’s locker room at Saraku, still naively assuming I’d be allowed to keep my underwear on underneath the yukata. You know—for reasons. For dignity. For mental stability. I also thought I’d be stepping into a private changing room—not a communal one.

But nope.

A staff member gave me a polite, practiced smile and said, “Please remove all undergarments before changing into the yukata.”

I froze. Time stopped. You mean, ALL-all?

Not even… the essentials?

She nodded again, like she’d just asked me to take my shoes off at someone’s house. No big deal. Except it was a VERY. BIG. DEAL. To me, at least.

Now, I’ve seen enough Korean and Japanese dramas to know how this scene unfolds—peaceful onsen steam, women gracefully wrapped in towel. I thought I was emotionally and mentally prepared. But here’s the plot twist: knowing and seeing—as in, seeing actual, unfiltered, unpixelated human bodies just vibing in their natural glory—are two wildly very different things. On TV, it’s cinematic. In real life? It’s me clutching my yukata like a lifeline, side-eying the floor tiles, and internally screaming while trying not to make accidental eye contact with someone’s very liberated front or behind. It’s not just nudity. It’s nudity with eye contact risk.

The Locker Room Trauma: Where Dignity Goes to Die

Ticket. Yukata. Locker key. Small towel. All good. I was ready. Or so I thought.

As I pushed open the women’s changing room door, I walked straight into an accidental National Geographic episode. Women of all ages were out there living their truth—some chatting naked, others powdering their backs, and others doing confident full turn like it was Tokyo Fashion Week for Nudity. 

And me? I nearly passed out. It felt like my retinas weren’t ready for this level of freedom. I was a statue of awkwardness. My heart thundered, my palms turned icy, and my fingers started trembling as I clutched my undergarments.

I couldn’t even look up. My eyes darted like a nervous squirrel. I tried to focus on anything—a tile, a locker number, a crack in the floor—anything but not bodies.

Because here’s the truth: I had never seen so much raw, unapologetic realness in one room. I grew up in a conservative home, surrounded by silence when it came to nakedness. We didn’t even talk about elbows. Now here I was, in a sea of confidence, trying to will myself invisible while removing my bra, and underwear like it was a defusal wire on a ticking bomb.

It was like performing surgery on myself with shaking hands.

Changing clothes in that locker room was a psychological obstacle course. I moved like a cat burglar trying not to set off alarms, except the alarms were my own thoughts. Was someone watching me? Were there hidden cameras? Is this how international scandals begin?

I tried to undress as discreetly as possible, clutching the yukata like a life vest, praying to every patron saint of introverts that no one was watching me—even though, of course, no one was. These women had mastered the art of minding their own business, but my mind was doing Olympic-level gymnastics.

The Burying Begins: Hot Sand, Weird Noises, and A Bit of Panic

Eventually, clothed in my cottony robe, I shuffled outside in resort-issued beach slippers. The sand bath itself was on a beach side pit, and the attendant guided us to our designated grave—I mean, spot. You lie down on the sand and they shovel steaming volcanic sand over you until only your head is left peeking out like a boiled egg on a breakfast plate.

I was buried. Alive. In Japan.

And oddly, it felt… good?

Yes, that’s right—when you’re buried in the hot sand bath in Ibusuki, you’re only wearing a yukata with no underwear underneath. It’s part of the traditional experience, allowing the heat to directly reach your body without any synthetic layers interfering.

Everyone around me looked serene—until the woman next to me let out a sound. A moan. Not a polite moan. A full-on “this-is-starting-to-sound-like-an-R-rated-movie” moan. I tensed. Was she okay? What’s happening? And then I heard a male voice say in Japanese, “Kimochi… kimochi…” (meaning “It feels good.”) and I had to bite my towel to keep from laughing out loud. But I also had to peek just to check if this was a sand spa or a scene from a forbidden film.

Turns out, she was just overwhelmed by the heat and got up a few minutes later, complaining about feeling dizzy. As for me, I could’ve stayed longer. The sand warmed me to the bones. I could feel it melting the stress from my shoulders and coaxing my inner chaos into silence. They only allow 10 minutes to avoid low-temp burns, but for a moment, I felt like I was floating under the earth.

Until it was time to rinse off.

Here’s how it usually goes:

1. You undress completely in the locker room (yup, including bra and underwear).

2. You put on the yukata provided by the facility, which is a light cotton robe.

3. You head out to the beach area where attendants bury you in the naturally heated sand, yukata and all.

4. After 10–15 minutes, you’re dug out, and you head to the onsen bath area to rinse off the sand (where again, you’ll need to be nude unless you request to skip it).

The Final Challenge: The Second Naked Gauntlet

We returned to the facility and were directed to the gender-segregated public bath for rinsing. I was already calculating how I’d wash quickly and go, still wrapped in my modesty and my robe.

Then came the second shock of the day. Which, again, means total nudity. Yukata off.

See, while I had somewhat recovered from the initial trauma of the locker room—of seeing more unclothed women in ten minutes than I had in my entire life—I wasn’t ready for Act Two. Back there, everyone had been bare. And me? I couldn’t even make eye contact. My hands had trembled while peeling off my undergarments, each clasp and fold feeling like a moral dilemma. It wasn’t just the nudity—it was the raw, unfiltered vulnerability of being so exposed, of unwrapping not just clothes but layers of cultural modesty I had carried my whole life.

And now, I was supposed to do it all again. This time, wet and barefoot.

A smiling female attendant, calm and polite in that quintessentially Japanese way, gestured toward the laundry basket and said something softly in Japanese. I didn’t catch the exact words—but I understood.

Her smile widened. “Please take off robe.”

I returned the smile, perhaps a bit too brightly. “Oh, no thank you.”

But she didn’t waver. The rules were non-negotiable. I could only enter with the tiniest towel imaginable—more like a damp napkin from a convenience store—which couldn’t cover a conscience, let alone a full-grown adult body. Just you, your thoughts, and whatever parts of yourself you were still trying to protect.

I FROZE.

I’d made it through the first round of communal vulnerability, but something inside me snapped at this point. My soul physically recoiled. My body was like, Nope. We’re done here.

I turned, wide-eyed and pleading, to the Japanese lady attendant and whispered in the softest panic,

“Is it okay if I… um… keep the robe on? Just for this part? Onegaishimasu (お願いします).

She looked at me, genuinely confused. “No. No robe. No yukata in onsen.”

That was when my mind went into full whirlwind mode, scrambling for anything—a loophole, divine intervention, an earthquake, a teleportation portal.

“Oh no, no, oh my God, no,” my thoughts spiraled.

I cannot walk in there—completely naked—into a pool full of strangers.

Not while the entire female population of Kagoshima casually soaked like it was a Tupperware reunion of confidence and coolness.

I was spiraling.

I called on all the angels and saints, the Blessed Mother, even the archangels I couldn’t name.

Please save me from this steaming vat of communal exposure.

And then—boom—salvation arrived like a heavenly Google search result.

“Religious reasons,” I blurted out, eyes wide with sudden conviction. “My faith, my religion… forbids nudity.”

Technically not a lie, if you consider my very real and personal belief system called: Avoid-Everything-That-Causes-Social-Anxiety-ism.

Her eyes widened with understanding. “Ah. Religion! OK, OK!”

She nodded, stepping back like I had just revealed a sacred vow, and waved me along with respect. 

GOD. BLESS. THAT. WORD.

And that, dear friends, is how I miraculously escaped the second wave of nudity—not with grace, but with one desperate, whispered word and a tiny hand towel I never even used.

How to Survive a Nudist Apocalypse (While Wearing a Robe and a Nervous Smile)

Inside the communal locker room, I could feel it—the subtle flicker of surprise from a few fully nude guests when they noticed me still wrapped tightly in my yukata like a burrito of modesty and confusion.

A few glanced up, politely curious. No judgment, just that quiet unspoken “Oh?” that floats in the air when someone stands out for wearing too much in a space designed for nothing at all.

I offered a polite bow.

Then a sheepish smile.

Then another bow, just to be safe.

And all the while, I clutched my robe like it was a life raft, a security blanket, a holy relic of personal boundaries. I half expected someone to come up and gently say, “Ma’am, are you lost? The clothed people’s room is down the hall.”

Honestly, I felt like a shy 10-year-old who had wandered into a European art exhibit—except the exhibit was alive, conversational, and completely comfortable in their skin.

Meanwhile, I still couldn’t look directly at anyone. My eyes darted to the floor, the ceiling, the locker numbers, a water stain on the tile—anywhere that wasn’t a human body.

Because somehow, the second time still felt like the first: overwhelmingly naked, overwhelmingly real.

And there I was—still the accidental guest at the naturist retreat, mentally reciting every coping mechanism I had while avoiding eye contact like it was radioactive.

The (Naked) Truth: What I Learned in Ibusuki

If you’re planning a trip to Ibusuki’s sand baths, here’s what you should know: the naked part isn’t optional—unless, by some act of divine mercy, you get a staff who respects boundaries and perhaps hears the word “religion” the way I whispered it.

Yes, I came to Ibusuki expecting a peaceful wellness retreat. I didn’t expect a spiritual confrontation with my own body image, modesty, and the awkward ghosts of puberty past.

But I left feeling lighter. Not just from the detoxing volcanic minerals, but from the quiet knowing that I had survived something uncomfortable and somehow made peace with it. Even laughed about it.

🏖️ Final Scoop from the Sandpit:

• Women cannot use the sand baths during menstruation or while pregnant. No exceptions, no debates—Mother Nature gets a hard pass here.
• The standard sand burial lasts 10 – 15 minutes, followed by an optional hot spring soak… which comes with a full-frontal disclaimer: clothing, swimsuits, and underwear are not allowed in the bathing area. That’s right—everyone’s going in as nature intended.
• No cameras, no photos. Please leave your phone and your curiosity in your locker. Respect the sacred silence and privacy of fellow bathers. We’re here to steam, not to stream.
• Take only your small hand towel with you to the bathing area. All other belongings—including clothes, underwear, and emotional support hoodies—stay behind in the changing room lockers or baskets.
• Bathing naked with strangers can feel hilariously awkward at first, but it’s an age-old part of Japan’s communal bathing culture. When in Ibusuki, do as the sand-baked locals do.
• If you’re modest, shy, or just spiritually allergic to public nudity, mentally prepare. Or memorize this phrase: 

Watashi no shūkyō wa sore o yurushite imasen (私の宗教はそれを許していません)—“My religion does not permit this.” or

Sumimasen ga, shūkyōjō no riyū de dekimasen.(すみませんが、宗教上の理由でできません) – “I’m sorry, but for religious reasons, I cannot do this.”

Bonus points if you say it with the calm of a monk and the conviction of a lawyer just like me.
