Product Line-Up
The Castella Collection
Each seal number below corresponds to the wholesale catalog listing — scan back to the table above for pricing and logistics.
Signature Sliced Castella
Original (Honey)
3 SlicesNagasaki Castella made with simple ingredients and baked in large batches for a uniquely moist texture and deep flavor. Foil-sealed for a 240-day room-temperature shelf life.
Matcha
3 Slices · Uji MatchaThe same moist Castella crumb, made with authentic Uji Matcha for a rounded, gently bitter finish alongside the classic honey sweetness.
Original (Honey)
5 SlicesThe same signature Original recipe in a larger 5-slice format — built for sharing, with the same 240-day shelf-stable seal.
Coffee — “Dejima”
3 SlicesSupervised by a professional barista for an authentic balance of rich bitterness and subtle sweetness. Specialty coffee is roasted within 3 days and ground fresh on baking day. Named after Dejima, the historic origin of coffee in Japan, with package art drawn from a rare vintage woodblock print.
Strawberry
3 Slices · Amaou JamMade with premium Amaou strawberry jam from Fukuoka to emphasize a rich, vibrant strawberry flavor and natural sweetness.
Lemon
3 Slices · New, July 2026A refreshing citrus aroma and rich lemon taste, made with premium Meyer lemons from Miyazaki. A higher ratio of egg whites gives a lighter, fluffier texture than standard Castella.
Lemon — 1 Piece
A single-piece option is a rare initiative in export food products. By lowering the absolute unit price, it significantly reduces the purchase barrier — making it much easier for new international consumers to try the product. Distributed across JR Kyushu station shops (Meihinkura) with proven sales at Nagasaki and Fukuoka Airports; pre-launch sampling with international travelers drew enthusiastic praise across nationalities.
Gift Assortment
Castella Assorts — 3 Boxes
Three individually wrapped packs (3 slices per pack) in one gift box. Individual portioning lets recipients enjoy each pack at their own pace without sacrificing freshness. Our primary proposal pairs two Original (Honey) packs with one Uji Matcha pack, though combinations can be customized within the same product series — a strong performer in overseas gift markets. The box surface itself carries a 3D scan of the actual Castella, so it looks just like real slices laid out inside — a small, eye-catching detail consumers love.
Frozen Specialty Line
Rare Castella (Plain)
A novel texture — fluffy on the outside, rich and meltingly soft within. When cut open, the luscious center flows out for a delightfully appealing presentation. Although the center appears semi-cooked, it is fully heat-treated and not raw. Frozen logistics keep export volume selective, but shipments have a strong track record to Singapore, Thailand, Malaysia, China, and Hong Kong.
Taiwan Castella
The recipe that evolved in Taiwan from classic Japanese Castella, brought back home. Its exceptionally airy, fluffy texture is truly addictive.
