Beppu’s sand bath (sunaburo) is one of the most unusual hot-spring experiences in Japan. Instead of soaking in water, an attendant buries you up to the neck in hot, mineral-rich black sand warmed by underground geothermal steam.
It sounds intense, but it’s actually one of the gentler Beppu onsen rituals. With a little preparation, school-age kids can absolutely join in. And unlike a naked communal bath, the yukata makes it far less intimidating for shy 8-to-10 year olds.
This guide explains the two main venues, current 2026 prices, age rules, what to wear, and the step-by-step flow. By the end you’ll know exactly whether to add a sand bath to your Beppu family day.
Planning the whole Beppu trip, not just the sand bath? This article zooms in on the sand bath specifically. For the full day-by-day plan, start with our complete Beppu with Kids family guide, then come back here for the venue details.
It also pairs well with the broader Kyushu onsen guide for families, which covers tattoo rules, baby etiquette, and private-bath alternatives across the region.
What Is a Sand Bath (Sunaburo)? A Quick Primer

A sand bath is a traditional Japanese therapy unique to a handful of coastal onsen towns. Hot spring water heats a bed of fine, dark sand to around 50-55°C (122-131°F).
You change into a light cotton yukata, lie down on the sand, and staff shovel warm sand over your body until only your head is exposed. You stay buried for roughly 10 to 15 minutes.
That’s the sweet spot for adults, and short enough that most kids who can sit through a regular onsen soak can handle it too.
Unlike a standard onsen where the heat comes from water, a sand bath applies even pressure plus warmth, which is said to boost circulation more than a regular bath. For families, two practical differences matter most:
- You stay clothed in a yukata, so it feels less exposing than a naked communal bath — useful if older kids are shy.
- It’s time-limited and sequential (sand → shower → hot spring soak), so it’s easier to pace with children than an open-ended onsen visit.
Beppu’s Two Main Sand Bath Venues: Takegawara vs Saraku

Beppu has two famous public sand baths. They have very different vibes, and the right pick depends on your kids’ ages and your tolerance for crowds.
Takegawara Onsen (Beppu city center)
Takegawara is the historic one — a beautiful 1938 wooden bathhouse in downtown Beppu, a 10-minute walk from Beppu Station.
The sand bath here is indoors, in a dim, atmospheric hall that feels like stepping back a century. Because it’s small and popular with tourists, waits of 30-60 minutes are common at peak times (weekends, late morning, early afternoon).
- Best for: Older kids (roughly 7+) who can wait patiently and enjoy the old-building atmosphere.
- Watch for: No reservations; queue system only. Limited English support.
Beppu Beach Sand Bath (Shoningahama / Saraku)
Officially the Beppu Beach Sand Bath, and often called Saraku locally, this venue sits right on Shoningahama Beach in the Kamegawa district, about 10 minutes by car or train from central Beppu.
The sand bath is set in a modern pavilion facing the sea, and on calm days you can hear the waves while you’re buried. It’s larger, better signposted in English, and generally friendlier for first-timers with kids.
- Best for: Families, first-time sand bathers, anyone who wants shorter waits.
- Watch for: On windy or rainy days the outdoor-feel pavilion can close or move indoors — check ahead.

Sand Bath Prices, Tickets, and Booking

As of 2026, both venues are in a similar price range and both operate on walk-in tickets only — no advance online booking.
- Takegawara Onsen sand bath: around ¥1,500-1,600 per person (includes a yukata and access to the regular bath afterward).
- Beppu Beach Sand Bath (Saraku): around ¥1,500 per person, similar inclusions.
- Children’s pricing: generally the same adult rate once the child is old enough to participate. Small children who join on a parent’s lap (where allowed) are usually free, but this is at staff discretion — ask at the counter.
Pay cash at the counter, change into the yukata in the locker room, and you’ll be called in turn. Peak times are 10:30-12:00 and 14:00-16:00.
If you can go right at opening or in the last 60-90 minutes before closing, you’ll usually walk straight in. Check the latest opening times on each venue’s official website before you go.
Because the sand baths themselves can’t be pre-booked, families who want a guaranteed Oita experience often pair the walk-in sand bath with a reservable Beppu activity. Browse pre-bookable Beppu & Oita day-tours and onsen passes on Klook →
Is the Sand Bath Safe for Kids? (Age Limits and Physical Requirements)

This is the question we get asked the most. Here’s the honest answer, based on our family’s visits and the posted rules at each venue.
- Minimum age: There is no universal legal minimum, but staff generally recommend the experience from around age 6-7, the age most kids can lie still for 10+ minutes and communicate if they feel too hot. Toddlers and babies are not suitable — the sustained heat and inability to self-regulate are a real risk.
- Height/weight: No strict requirement, but the yukata sizing starts around 120 cm. Smaller kids may swim in it; that’s fine for the sand bath itself but awkward in photos.
- Medical exclusions: Pregnancy, high blood pressure, heart conditions, recent surgery, fever, and open wounds are all contraindications. Staff will ask at check-in.
- Heat tolerance: The sand is hot but not burning. If your child hates warm baths at home, they’ll likely dislike this too. If they happily sit in a 40°C onsen, they’ll be fine.
For younger kids and babies, a private kashikiri onsen in Beppu is a much better match. You get the hot-spring experience at a temperature and duration you control, with no time pressure from other bathers.
If your trip dates are fixed and you want to lock in a ryokan or hotel with a bookable private family bath, the easiest way is to filter by “private onsen” on a hotel aggregator. Check Beppu hotels with private family baths on Agoda →
What to Wear and What to Bring for a Family Sand Bath Visit
Sand baths are a bit gear-heavy compared to a normal onsen. Here’s our family packing list, refined over two visits:
- Swimwear or underwear under the yukata: Both venues provide a cotton yukata. Most people wear nothing underneath (it’s cleaner), but modesty-conscious older kids can keep on underwear or a swimsuit. Avoid anything that will stain from the minerals.
- Hair tie or shower cap: Long hair gets sandy. Tie it up high or use a thin shower cap — you can buy one at most Beppu pharmacies for ¥100.
- Face towel: Provided at Takegawara; usually for sale (¥200-300) at the Beach Sand Bath.
- Water bottle: Drink before and after. The sand bath dehydrates you fast.
- Flip-flops or slip-on shoes: Easier than laces when you’re shuttling between changing room and sand pavilion.
- Diapers and changing supplies: Bring your own. Diaper change tables exist at the Beach Sand Bath’s main lobby but not inside the bath area itself.
Breastfeeding: Neither venue has a dedicated nursing room, but the women’s changing area is private enough for a quick feed.
If you plan to stay nearby, many family hotels in Beppu like Suginoi have proper nursing rooms and private family baths you can use before or after.
Suginoi in particular is a self-contained resort with a kids’ pool, buffet, and bay-view bath. It’s popular enough that summer and Golden Week dates routinely sell out two to three months ahead — if your trip lands in those windows, book early or you’ll be priced into the leftovers.

Step-by-Step: What Actually Happens During a Sand Bath
If you’ve never done it, here’s exactly what to expect from arrival to exit. Plan for roughly 60-75 minutes end to end.
- Buy tickets at the counter. Point at the sand bath option; staff speak enough English at the Beach Sand Bath to get through this step.
- Change into the yukata in the gendered locker room. Lock your clothes away. Bring only your face towel into the bath area.
- Walk to the sand pavilion and lie down. An attendant guides you to a dug-out spot and helps you lie flat. Then they shovel warm sand over your body — starting at the feet, ending at the shoulders. Your head stays out on a small wooden pillow.
- Stay buried for 10-15 minutes. You’ll feel the weight first, then gradually the heat. If it gets too warm (especially for a child), wiggle a hand free and wave — staff will come dig you out early. This is normal and fine.
- Sit up, brush off the sand, and walk to the shower area. Rinse thoroughly — sand gets everywhere.
- Soak in the regular onsen bath (included in your ticket) to finish. This is a standard naked onsen at both venues, so plan accordingly with older kids and mixed-gender family groups.
- Dress, rehydrate, and leave. You’ll feel pleasantly tired, like after a warm bath plus light exercise.
Sand Bath Hours, Closures, and Weather Considerations
Both venues keep irregular hours, so always check the official site or call ahead — especially if the sand bath is the main reason for your Beppu detour.
- Takegawara Onsen: Generally open 8:00-22:30 for the regular bath, with sand bath sessions 8:00-21:00 (last entry ~20:30). Closed the third Wednesday of each month.
- Beppu Beach Sand Bath (Saraku): Generally 8:30-18:00 (last entry ~17:00). Closed the fourth Wednesday of each month, and occasionally for weather.
- Closures: Searches like “beppu beach sand bath closed” usually point to either the monthly maintenance day or weather closures. Strong wind, heavy rain, and very cold snaps can all pause the outdoor-style operation at the Beach Sand Bath.
If you arrive to find it closed, don’t panic — Beppu has plenty of indoor backups. Our rainy day Beppu guide for families covers covered arcades, indoor hot springs, and kid-friendly museums that work as fallbacks.
Combining the Sand Bath with Other Beppu Family Activities

A sand bath plus shower plus soak takes roughly 60-75 minutes, which makes it an easy half-morning or half-afternoon block to slot into a wider itinerary. Here’s how our family typically chains it with other Beppu stops:
- Morning sand bath + Hells (Jigoku) tour: Open Saraku at 8:30, finish by 10:00, then drive 15 minutes to the Beppu Hells (Jigoku) circuit with kids. Lunch near Kannawa.
- Afternoon sand bath + Suginoi pool: Visit Takegawara at 14:00 (lighter crowd than morning), then head up the hill to Suginoi for the family pool and dinner buffet.
- Day-trip from Fukuoka: If you’re basing in Fukuoka, see our Beppu day trip from Fukuoka itinerary for the realistic 1-day pacing with sand bath included.
For families who want the experience without the queueing logistics, pre-booked Oita activity passes and small-group day tours can be a clean alternative. See bookable Beppu & Oita tours and onsen passes on Klook →
Beppu Sand Bath FAQ for Families
Is the Beppu sand bath worth the price for kids?
For school-age kids 7+, yes — it’s a genuinely novel experience that you can’t replicate at home or in most other onsen towns, and ¥1,500 is fair compared to most paid attractions. For under-5s, skip it and book a private family onsen instead.
If you’re still on the fence, bundling the sand bath with a Klook-bookable Beppu activity gives you a guaranteed reservable backup if the walk-in queue is too long. Browse Beppu activity passes on Klook →
Can babies or toddlers join the sand bath?
No. Staff at both venues actively discourage it because the sustained 50-55°C heat is too high for a body that can’t self-regulate or clearly communicate discomfort. Use a private kashikiri onsen instead.
Do we need to book ahead?
No — both venues are walk-in only. To avoid queues, arrive at opening or in the last 90 minutes before closing.
Where should we stay near the Beppu sand baths?
Suginoi Hotel (resort feel, family pool, bay view) and the cluster of hotels around Beppu Station are the two easiest bases for families. Compare Beppu family hotels on Agoda →
