## 'Mrs. Yukiguni' (Mrs.雪国)
### The Birth Story of 'Mrs. Yukiguni'
In November 2025, Mybase opened its doors in a 'shutter street' (abandoned shopping district), a challenge seen across Japan. The concept was to create a place that makes mothers feel, 'I want to raise my children in this town because this place exists.'
Why open Mybase in a depopulating rural area?
It was driven by the desire of Misato Hisada (known as Misato), CEO of Mybase Co., Ltd., to give back to Uonuma, the town that raised her.
At the same time, in November 2025, the president of Midorikawa, a representative sake brewery in Uonuma with a 140-year history, handed over the leadership to the 6th generation. Midorikawa once had its brewery in the shopping district and was at the center of the town's prosperity during the 1970s.
Mybase: 'Increasing family smiles.'
Midorikawa: 'Increasing smiles through sake.'
'Mrs. Yukiguni' was born from the shared vision of these two leaders—the historic brewery and the local venture.
This luxurious cheesecake, blended with high-quality sake lees from Uonuma, one of Japan's top rice-producing regions, is designed to bring smiles to mothers' relaxation time and families' reward time.

### Background of Development
After leaving Uonuma for 15 years and returning, Mybase CEO Misato was deeply moved by how rich a 'production area' her hometown was. Having started childcare in a 'consumption area' (city) and remembering the fear when logistics stopped during the COVID-19 pandemic, her appreciation was even greater.
While relearning about her hometown, Misato—a mother of three—discovered that sake lees, a superfood that helped her own parenting, had previously been treated as 'industrial waste.' Although some find the scent of sake lees strong, she was convinced of its high benefits from her own experience.
'If I can help families smile more by making it easy to incorporate sake lees into their lives...'
She realized that utilizing sake lees could simultaneously achieve family smiles and regional revitalization! That's how the story of 'Mrs. Yukiguni' with Midorikawa began.
### About 'Mrs. Yukiguni'
