Hotel Pools in Japan: What’s Different?
In the US, Europe, and many parts of the Middle East and Asia, hotel pools are often casual, all-ages, and included in the stay. In Japan, pools are frequently treated as fitness or wellness facilities, and their primary purpose is not family fun. Some are designed for lap swimming, some are meant for quiet soaking, and many are simply off-limits to younger children.
That beautiful pool in the hotel listing? It may come with a long list of rules that can turn excitement into disappointment.
Luca & Nico’s Tip: That amazing-looking pool may look like a dream, until you find out your kids can’t use it at all.
Common Rules & Restrictions That Surprise Families
Age Limits
- Many hotel pools in Japan are not open to babies, toddlers, or even kids under 12.
- Children must often be accompanied by an adult in the water at all times.
- Some pools do not permit children who are still in diapers, even swim diapers.
Swim Cap Requirements
- Swim caps are commonly required, even for short hair.
- These are not usually provided for free. You may need to buy or rent one onsite.
No Toys, No Splashing, No Fun?
- Floaties, water toys, diving, and jumping are often not allowed.
- Some pools prohibit loud voices or games in the water.
- Pools are frequently designed for quiet use, not energetic play.
Extra Fees (Even for Hotel Guests)
- Many hotels charge extra to use the pool: anywhere from ¥1,000 to ¥5,000 per person, per day.
- Pool use may be limited to guests in premium rooms or club floors.
- Towels, caps, and locker usage may also carry fees.
Seasonal Closures
- Outdoor pools in Japan are generally only open from mid-July to late August.
- Even if the weather is warm, pools may be closed in spring, early summer, or fall.
Tattoos Not Allowed
- Visible tattoos (common among foreign visitors) are often banned.
- Some hotels will provide cover stickers, but others may deny entry entirely.
Reservation-Only Access
- Some hotel pools require advance booking, even for guests.
- Usage may be limited to 30- or 60-minute time slots.
- Walk-in access is often not available during busy periods.
Why Some Families Still Choose Pool Hotels
Despite the challenges, hotel pools can still be worthwhile under the right conditions:
- You’re traveling in July or August and want a place to cool down.
- You’re staying multiple nights and building in rest days.
- Your kids are older and understand how to follow pool etiquette.
- You’re staying at a resort-style hotel that explicitly welcomes children and has family-friendly pool features.
When to Think Twice About Booking a Pool Hotel
Booking a hotel for its pool may not be worth it if:
- You’re traveling in off-season months (October to May).
- You’re doing a fast-paced itinerary with little hotel downtime.
- Your children are under 6 or not toilet trained.
- You assumed the pool would be free, open-access, and kid-friendly.
- You have visible tattoos or are relying on swim toys to keep kids entertained.
Questions to Ask Before Booking
To avoid disappointment, ask the hotel (or check their website) for details:
- Is the pool open year-round or only during summer?
- Are there age or height restrictions?
- Are swim caps required?
- Can kids bring floaties or toys?
- Is the pool supervised? Is adult accompaniment required?
- Are there time limits or required reservations?
- Is there an extra cost to use the pool?
- Are guests with tattoos allowed?
Alternatives to Consider
If a hotel pool doesn’t seem like the right fit, try:
- Hotels with family lounges, kids’ play areas, or indoor playgrounds.
- Booking a stay at a public pool or onsen water park with kid zones.
- Staying at an onsen hotel with private family baths that allow kids.
- Choosing a hotel near a splash pad, river play park, or indoor amusement area.
Until Next Time…
In Japan, a hotel pool isn’t always the highlight it appears to be in photos. With limited availability, strict rules, and unexpected costs, many families find the pool goes unused or becomes a source of frustration.
If the pool is central to your booking decision, take time to verify the details before you commit. Otherwise, you may be better off choosing a hotel that offers space, convenience, or cultural experiences, and spending your time (and money) exploring Japan beyond the water.
Stay curious, stay adventurous, and keep dreaming!
