Nagasakiya | Brown-Sugar Castella Sweets in Kuninaka (Irabu, Miyako)

Nagasakiya is a small handmade sweets shop in the Kuninaka village of Irabu Island. Its signature product is "kokuto castella", richly kneaded with local sugarcane molasses. With a moist, rich sweetness and full-bodied flavour, it is an Irabu-Island-exclusive treat that many travellers rate as "the most delicious castella of my life". As the owner bakes each one carefully one by one, the daily output is limited, and a queue can form at afternoon snack time. If you want to be sure of getting one, requesting a set-aside by phone in advance is recommended. At 1,400 yen (approx US$9) per loaf, it is perfect as a souvenir or for yourself. With good access about 5 to 10 minutes by car from Shimojishima Airport, it is an easy location to drop by while sightseeing on Irabu Island. Do try this rustic, warm-hearted flavour unique to the island.

Visiting tips & what to bring

The shop is within the Kuninaka village, with a small car park for 2 to 3 cars. When full it becomes roadside parking, so take care not to obstruct traffic. Being a popular product it may sell out, and a queue forms easily at snack time (around 14:00 to 16:00), so a morning visit or advance phone booking and set-aside is reassuring. The castella needs refrigeration and has a short best-before date, so be mindful of the carry-home time. Being a facility type, there are no particular cautions about outdoor equipment.

For families with small children

It is a sweets shop easy to drop by even with small children. The gently sweet kokuto castella is perfect as a snack and suits family souvenir-choosing too. However, the interior is small and purchasing is mainly at the shopfront. As a long stay with a pushchair or in-shop eating space is hard to expect, savouring it at your hotel or on the beach after buying is recommended. The few parking spaces also make advance confirmation advisable for families coming by car.
