Izumi Group's "Yume-Ichi" PB Brand Launches "Kaijyu Lemon Chuhai" on June 30

Izumi Co., Ltd. has announced that its private-brand (PB) label "Yume-Ichi," sold at 260 Izumi Group stores, will launch the new product "Kaijyu Lemon Chuhai" on Tuesday, June 30.

What is 怪獣レモン (Kaijyu Lemon)?

Kaijyu Lemon is an "upcycled" — creatively re-purposed — lemon grown in the Setouchi region. Although the flavor and quality are the same as any other lemon, these fruits are typically discarded or sold at low prices due to irregular appearances. Through thoughtful design and creative ideas, Kaijyu Lemon gives new value to lemons that would otherwise go to waste, turning them into a celebrated brand.

"On Ikuchijima Island's relatively warm climate, our lemon trees bloom in May and the harvest begins in mid-October. I walk the orchard every day to bring lemons you can eat with confidence to customers across Japan."

"Kaijyu Lemon was born for lemons that couldn't receive the recognition they deserved because of how they looked. We launched this brand to give them new value and deliver them alongside the passion of the farmers who grew them. We are deeply honored that Izumi Co., Ltd. has chosen to feature our product under the 'Yume-Ichi' private-brand label. Seeing a locally-grown initiative spread through 'Yume-Ichi,' a label beloved by so many customers, is a tremendous encouragement for our farmers. Kaijyu Lemon is more than just a lemon brand — it has grown as a brand that connects growers, companies, and consumers while confronting the challenges facing regional agriculture. Through this product, we hope to share not only the delicious taste of Setouchi lemons, but also the stories and the passion of the people who grow them. We will continue working with many people to raise the value of our region and contribute to the development of agriculture and food culture in Setouchi."
