Producer-run sweet potato parfait shop Kinmitsudo unveils two new Kinmitsu-imo parfaits for summer and autumn

Satsumaimo no Ishida Nouen Co., Ltd. (Head office: 876 Arakita, Katori, Chiba; President and CEO: Masahiko Ishida) announced that Kinmitsudo, its producer-run specialty shop for sweet potato parfaits, will launch two new seasonal parfaits for summer and autumn. The first will be served at the main shop from Friday, June 5, 2026. The new parfaits, the shop’s first in about two years, are the summer sweet potato parfait “Croissance” and the autumn sweet potato parfait “Maturation.” The theme is “a magic wand made of sweet potato.” Built on the sweetness and texture of sweet potatoes, the products pursue aroma, lingering flavor, layered textures, and above all, fresh combinations. As sweet potatoes shift from an autumn-only food to an ingredient enjoyed year-round through chilled baked sweet potatoes and sweet potato desserts, Kinmitsudo aims to propose the next value as a producer. The company says sweet potatoes are no longer limited to sweet baked potatoes; their potential as dessert ingredients has expanded significantly. Rather than simply increasing sugar content, Kinmitsudo wants to raise the value of sweet potatoes themselves and offer ideas that can inspire the next wave of sweet potato desserts. It hopes its summer and autumn directions will encourage others in the industry to explore lighter sweet potato sweets for summer and richer, more aromatic combinations for autumn. The two new parfaits were developed using insights gathered through department-store events across Japan, including regional taste preferences, seasonal sales patterns, ingredient pairing ideas, and the moments that make customers want to try something. They are not merely parfaits using sweet potatoes, but products born from the question of how sweet potatoes can be enjoyed in a more fun and novel way. Kinmitsudo emphasizes not just sweetness, but the reason behind each product’s design. The brand aims to let customers experience the agricultural intent and the full process behind the flavor, from soil preparation and aging to roasting tests, translating the technical expertise of a producer into seasonal desserts. The summer parfait “Croissance,” meaning “growth” in French, expresses sweet potatoes as a light dessert suitable for hot weather. It combines lemongrass jelly, cassis-blueberry sauce, yogurt cream, Earl Grey panna cotta, matcha meringue, Kinmitsu-imo baked sweet potato, and Kinmitsu-imo Mont Blanc cream. It will be available from Friday, June 5, 2026, priced at 2,200 yen including tax. No reservation is required. The serving location is Kinmitsudo, 3403-8 Sawara-i, Katori, Chiba. The autumn parfait “Maturation,” meaning “aging” in French, highlights the depth, richness, aroma, and roasted notes of sweet potatoes. It includes pear gelato, miso crumble, handmade caramel cream, chocolate ganache, hojicha and tonka bean jelly, Kinmitsu-imo baked sweet potato, and Kinmitsu-imo Mont Blanc cream. It will be available from Saturday, September 19, 2026, priced at 2,200 yen including tax, at the same Kinmitsudo location. Brand owner Yudai Ishida said the two products took several months to develop, with the team reconsidering how to communicate the story of the production site through parfaits while listening to customer feedback and testing repeatedly. The goal was to express the story of sweet potato growth from seedling preparation in May through full maturation in December, while creating excitement that makes customers want to visit and try the new items. Kinmitsudo is a sweet potato pastry cafe operated by Ishida Nouen in the historic Sawara area of Katori, Chiba. It serves baked goods, sweets, and parfaits using the farm’s Kinmitsu-imo® sweet potatoes as well as non-standard items generated during production. As a directly operated shop, it welcomes more than 20,000 visitors annually and serves as a place where customers can experience the value of sweet potatoes.
