We look forward to welcoming everyone at "Booth No. 33."

Background of Exhibition

The "Vegan Gourmet Festival" is an event themed around vegan food (gourmet), which is gaining attention due to its sustainable background, being kind to people, animals, and the earth.

Oizumi Factory decided to exhibit, believing it to be a point of contact to directly connect with customers who have various food choices and to co-create new lifestyles.

"_SHIP KOMBUCHA," manufactured and sold by Oizumi Factory, and "planet rolls," born from the plant-based cafe "1110 CAFE/BAKERY" operated by the company, propose an experience that makes plant-based choices more enjoyable and enriching for both vegans and non-vegans in their daily lives.

Kombucha is a plant-derived "fermented sparkling tea" made by adding sugar to tea and fermenting it with "SCOBY" (Symbiotic Culture Of Bacteria and Yeast). "_SHIP KOMBUCHA" is an organic kombucha brand brewed using natural ingredients such as naturally grown produce, without any added fruit juice, flavors, or preservatives. It is carefully brewed by artisans over time, from tea extraction to fermentation and bottling, at one of the few non-heat-treated kombucha breweries in Japan.
