Hyatt Regency Seragaki Island, Okinawa: Four Nights with Three Generations

Q: Will you still be upgraded over Obon?

We were — a corner ocean-view room on Globalist, though not a suite at that time of year. Upgrades depend on availability and are never guaranteed.

Q: Is the club lounge workable with children?

Yes. They make balloons for children; it is clearly run with families in mind.

Q: Does Kafuu need a booking?

In peak season, yes. They were running a 90-minute limit when we visited.

Over Obon in August 2026 we spent four nights with six people across three generations at the Hyatt Regency Seragaki Island in Onna. It is a hotel full of families with small children. This article covers the room, the club lounge, the gym and the restaurant across the road; the pools have their own article.

1. The room: a corner ocean view, even over Obon

We were upgraded on Globalist, the top tier of World of Hyatt. Not a suite — it was peak Obon — but a corner room with an ocean view, which was lovely.

*From the balcony. The sea is simply there*

*A corner room, so the view opens out in two directions*

*Our daughter settling into the room. Being a corner room, the windows are wide.*

We could watch the sunrise from the room, too. It was cloudy, admittedly. Still worth the early start.

*Morning sea from the room. Heavy cloud that day*

*As it lightened, the outline of the island appeared*

*The grounds from the terrace side — red tiled roofs, unmistakably Okinawa*

2. The club lounge: draught beer, any time

For a family across three generations, the club lounge was what made the stay.

First: draught beer is available at any hour. Not having to watch the clock is, honestly, a real pleasure.

*The lounge beer tap — Orion, poured yourself*

*Breakfast. There is enough variety that the children always found something.*

We had breakfast there as well. There is enough variety that there is always something a child will eat, which matters more than it sounds.

*The breakfast buffet, Japanese and Western*

*Fruit and dessert — where the children head first*

And they made balloons for the children. Small things like this add up over a stay.

*A balloon from the lounge. It travelled back to the room with us*

3. Over Obon the cocktail hour began at 3pm

We only found this out on arrival: the cocktail hour, normally from 5pm, was running from 3pm over the Obon period.

Two hours earlier makes a real difference with children, because it fits the hours they actually eat. We could come straight up from the pool into the lounge.

*The lounge in the late afternoon — watermelon out on the counter*

📌 This is very likely an Obon-only arrangement. Operations vary by season — ask the hotel directly before you stay.

4. The gym: kit and shoes lent free

This seems to be under-advertised: both workout clothes and shoes are lent free of charge, and apparently not only to Globalists.

Not having to pack gym kit is a genuine saving of luggage.

To be honest, there are not many machines, and it is not a well-equipped gym. But it is never busy, so you never wait. In the mornings we had it almost to ourselves.

5. Kafuu, across the road: Agu pork shabu-shabu

Directly opposite the hotel is Kafuu, an Okinawan restaurant serving shabu-shabu. We went for the Agu pork.

*The noren at Kafuu — Okinawan food and shabu-shabu*

*Shabu-shabu at Kafuu, three generations around one table.*

*With their grandparents. The children were in high spirits throughout.*

Even the highest course is a little over ¥6,000 per person. We mixed a course with a la carte dishes and paid a little over ¥30,000 in total for six — about ¥5,000 each.

📍 Kafuu Seragaki — Agu pork shabu-shabu and Okinawan food — 1105-1 Seragaki, Onna, Kunigami District, Okinawa / +81 50-5492-6233 / dinner 17:00–23:00 (L.O. 22:00) / lunch 12:00–15:00 / official site

In peak season you must book. It was full, and running on a 90-minute limit, which made the meal a little rushed.

6. We liked it enough to go back — with four of us

It was good enough that we returned on day four. But we left the grandparents behind and went with four.

There was a reason. For elderly parents, Agu pork — for all its quality — was too rich. That was one of the things three generations taught us: a restaurant can be excellent and still not suit everyone.

Second time round we ordered less meat and more of everything else. The squid-ink somen chanpuru was the standout.

*Squid-ink somen chanpuru — the best thing we ate there*

With less shabu-shabu, four of us paid about ¥15,000 in total — roughly ¥3,800 each, less per head than the first visit.

📌 With grandparents: pick somewhere you can adjust the order a la carte rather than committing to a set course per person. Rich dishes are easier to manage that way.

7. The hotel overall

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

*The road in front of the hotel, right on the coast*

*The club lounge, bright along the window side*

It is a hotel full of families with children. Being somewhere your children don't stand out when they get loud matters more than you expect — nobody in our group had to stay on edge the whole time.

*Morning sea. Perhaps the real value here is having time in which nothing has to happen*
