Ariake Kaikou Harbor Matcha Kuromitsu (Matcha & Black Sugar Syrup Cake)

Kaikou Harbor Matcha Kuromitsu is one of Yokohama’s most elegant souvenir sweets, and a proud addition to the beloved Harbor cake series. It is produced by Ariake. This ship-shaped cake celebrates Yokohama’s rich history as a port city that opened to the world in 1859 — when tea was one of the city’s most prized exports.

At the heart of this cake is a homemade matcha bean paste crafted with “Banjo no Ao,” an exclusive original matcha developed in collaboration with Yasuyuki Suda, a master tea craftsman of the highest national rank (Chashi Judan) from Houkoudou, a long-established Uji tea house in Kyoto.

Grown in the misty tea gardens of Minamiyamashiro Village, Kyoto — Japan’s premier Uji tea-growing region — this specialty matcha is vibrant in color and deeply aromatic. Nestled inside the matcha paste is a filling of sweetened candied chestnuts and rich matcha kuromitsu (black sugar syrup), all gently wrapped in a thin, moist castella-style sponge and baked to perfection using a traditional method.

The result is a beautifully layered cake — subtly bitter matcha, deep sweetness from the kuromitsu, and the gentle texture of chestnut — a refined harmony that reflects both Yokohama’s culture and Japan’s finest tea heritage.

Enjoy Ariake Kaikou Harbor Matcha Kuromitsu — a Yokohama souvenir cake that brings history, craftsmanship, and premium matcha together in every bite.
