What is Jubako Box Uni? Sourced from our home in Hokkaido, this premium Uni is presented in a traditional Jubako Box (重箱) — a Japanese lacquered bento box reserved only for special occasions like New Year celebrations. This brand is often referred to as the "Yokozuna" (Champion) or #1 Special Uni of the market. There is an average of 10,000 Uni stacked up at the Uni auction every day, and this brand always wins the #1 tag out of all Uni. The grade of Uni is dictated by a number with #1 being the best — only the finest specimens earn this distinction.
