Why it's worth your hours

A drowned coastline: hills that became islands when the sea rose, leaving 208 wooded islets in about twenty-five kilometres of water. It is the densest island cluster in Japan, and only four of them are inhabited. Kujukushima means "ninety-nine islands," which is an old way of saying "too many to count" — and it undercounts by half.

The whole area is inside Saikai National Park. The fifty-minute sightseeing boat threads between the islets close enough to see the pines, and it is a scheduled public service at a fixed fare — no booking, no tour operator, no markup.

Do it right

Five things the plaques won't tell you

Check the sailing board when you arrive and build the rest of the day around it. It is the only fixed timetable here.
Sit on the open upper deck. The islands pass close and the enclosed cabin wastes the trip.
Umikirara aquarium is beside the pier, indoors, and unusually good on jellyfish.
Oyster huts operate along this shore from about November — grilled by the bucket over charcoal.
Sea kayaking runs from the same resort in sheltered water, and is easier here than it sounds.

Quick answers

FAQ

How many islands are in Kujukushima?

Two hundred and eight. The name means "ninety-nine islands," which in older Japanese usage meant simply "too many to count" — so it undercounts by half. Only four are inhabited, and the whole area lies within Saikai National Park.

Do I need to book the Kujukushima boat?

No. It is a scheduled public sailing at a fixed fare of around ¥1,800, roughly hourly, with no tour operator and no markup. Check the sailing board when you arrive at Pearl Sea Resort and build the rest of your day around it — it is the only fixed timetable in this port.

Whatever the plan: back aboard 60 minutes before all-aboard. Full port context on the Sasebo guide.
