Working the Hotel Pools in Okinawa: Indoor, Saltwater, Night Pool and Fireworks

Q: Can you swim on a rainy day?

Yes, if there is an indoor pool. We spent an entire wet day in ours. Check for one before you book.

Q: Is there anything for very young children?

There is a shallow children's pool, with balls floating in it — usable before they can swim.

Q: Is a night pool good with kids?

Yes. With the heat gone, it is far less draining than daytime. It is busier, though.

Q: Are there fireworks every night?

Possibly only over Obon. We saw them at 8.30pm. Check with the hotel in advance.

On a family trip to Okinawa, the hotel pool is not a bonus — it is the itinerary. Across four nights at the Hyatt Regency Seragaki Island we were in the water every single day, including the wet one. Here is how we actually used them.

The night pool, and fireworks at 8.30pm

1. One day was a washout. The indoor pool saved it

📍 Hyatt Regency Seragaki Island Okinawa — 1108 Seragaki, Onna, Kunigami District, Okinawa / +81 98-960-4321 / official site

One of our four days brought heavy rain — a 100% chance of it.

August in Okinawa turns fast even when it looks clear. At a hotel with only outdoor pools, that day would have been lost entirely.

*The indoor pool. Somewhere to retreat to when it rains*

*Indoors, so the weather stops mattering*

It ended up being the day we felt most rewarded for our choice of hotel. If you are taking children to Okinawa, whether there is an indoor pool is worth checking first.

*The indoor pool at night — quiet, and almost empty*

2. There is a saltwater pool and a freshwater one

The resort has both saltwater and ordinary freshwater pools.

With children this quietly matters. Some children hate salt water in their eyes, and having a freshwater pool means you can simply say “today, that one”.

*The outdoor pools run straight into the beach*

*Drifting on a float. You float more easily in the saltwater pool.*

*Hanging onto the float. In the shallow end they can play on their own.*

*This was the mood for the whole afternoon.*

*From above: several pools, linked together*

*The rock-edged section changes the character*

3. There is a shallow pool for small children

*The shallow pool for small children, with balls floating in it*

*The flamingo float. Because there is a shallow area, this can go on for hours*

*Beside the children's pool. They brought toys in and played.*

*Even with a float, it is shallow enough to watch without worrying.*

There is also a shallow pool for younger children, with small balls floating in it, so children too young to swim still have somewhere of their own.

As we wrote in choosing a beach resort with kids, the presence of a shallow area completely changes how long you can stay. A uniformly deep pool buys you an hour; a shallow one buys you the whole afternoon.

*The shallow section, running out toward the beach*

*Loungers and parasols along the poolside*

*A jacuzzi among the trees — where the adults recover*

4. The night pool was the best of it

The night pool was what stayed with us. Lit up, it becomes a different place entirely.

*The lit pool. Nothing like it looks by day*

*Purple and blue on the surface of the water*

*The night pool. The lighting shifts slowly through colours.*

*In the water the light plays across you.*

*The two of them out on a float together.*

*It is quieter at night, so there is room for the floats.*

Honestly, it is busy — Obon will have had something to do with that. Even so, being able to swim once the heat has gone is a real gift with children. It costs them far less than the middle of the day.

*The lights under the water. This alone was enough for the children*

5. Fireworks at 8.30pm

Fireworks went up at 8.30pm, visible straight from the night pool.

*Palm silhouettes against the fireworks*

*The end of the day. The children did not look away*

📌 This may only run over Obon. Whether they happen at all, and at what time, varies by season — check with the hotel before you stay.

6. The hotel pools are emptiest in the morning

The unexpected sweet spot was early morning — far quieter than the middle of the day.

*The poolside in the morning — towels laid out, nobody in yet*

With grandparents along, the midday sun is what costs them most. Splitting pool time between morning and evening let everyone keep going comfortably.
