Discover Nuka Fermentation: An Event Recap

On May 16, 2026, Y-Yacht Corporation, a company based in Nagoya, Japan, specializing in kitchen and dining goods, hosted an engaging talk show and demonstration titled ‘My First Nuka Bed’ at Isetan Shinjuku’s 5th floor Kitchen Dining studio. The event featured noted culinary researcher and fermentation enthusiast, Rieko Teramoto, who shared her expertise and passion with attendees.

This event was part of the ongoing pop-up store for Nichinichi Tools, running from May 13 to 26, 2026. Rieko’s philosophy of making nuka-zuke (fermented rice bran pickles) accessible and seamlessly integrated into modern meal contexts perfectly aligns with the brand’s mission: to blend traditional Japanese tools with contemporary lifestyles.

During the event, Rieko demonstrated the process of making a nuka bed using the signature round canisters from Nichinichi Tools, emphasizing the health benefits linked to ‘choukatsu’ (gut health) that are brought about by nuka fermentation. Participants were treated to an array of nuka-zuke variations that included not just the usual cucumbers and carrots but also pumpkins, lotus roots, corn, konjac, eggs, and avocados—totaling eighteen unique pickled items.

An intimate gathering of just six participants allowed for a more personal experience, where they could interact with Rieko and immerse themselves in the concept behind Nichinichi Tools. Additionally, the attendance is set to repeat on May 24, 2026, at 14:30, although the slots are currently filled to capacity. However, walk-ins for observation will be welcomed, albeit without the tasting or takeaway set.

Understanding Nuka Fermentation

To kick things off, Rieko elaborated on the remarkable health benefits associated with maintaining a nuka bed and introduced the golden ratio for beginners, utilizing the Nichinichi Tools’ enameled round canister. Known for its resilience to acids and salt as well as its non-odor absorbing properties, this canister is an ideal material for nurturing a nuka bed. Measuring at a compact 11.6 cm in diameter and 16 cm in height, it fits comfortably within traditional refrigerators, holding around 800g of nuka—perfect for single households or small families striving to enjoy fermentation at their own pace.

The Right Way to Nurture Your Nuka Bed

Rieko also shared invaluable tips on how to maintain a healthy nuka bed through everyday TLC, alongside important observation points to keep it thriving. As the workshop progressed, participants kept diligent notes while already experiencing the exciting concepts through tasting nuka-zuke-inspired dishes like ‘Nuka-zuke Potato Salad with Egg and Cucumber’ and ‘Shumai with Pickled Lotus Root.’ The dishes showcased how utilizing nuka-zuke goes beyond just eating it as is; they can enhance flavors with natural umami and subtle acidity without needing additional seasoning.

Towards a New Nuka-zuke Lifestyle

The overarching theme promoted through this event is to alleviate the challenges often associated with nuka-zuke preparation. Rieko aims to introduce a new nuka-zuke lifestyle that doesn’t revolve around large barrels but utilizes Nichinichi’s small canisters to encourage users to enjoy the cultivation process while also emphasizing the joy that comes in sharing these handmade creations with families and loved ones.

Having been established in 1949, Y-Yacht Corporation remains a frontrunner in kitchen and dining solutions, striving to promote Japanese tools that enhance daily living experiences. Now, with Rieko Teramoto’s guidance, they hope to turn nuka fermentation into a common household practice.
