The "Otona no Yaruki Pen" (Adult Motivation Pen), a buzzworthy product in the adult reskilling market, now comes in a highly anticipated "Black Model"!

KOKUYO Co., Ltd. (Headquarters: Osaka City / President: Hidenori Kuroda) will launch an upgraded model of its IoT stationery, the "Otona no Yaruki Pen," which "visualizes" daily efforts, on July 1, 2026 (Wednesday). This update introduces a new color, the "Black Model," which has been highly requested by users, and significantly improves basic performance.

The "Otona no Yaruki Pen" is an IoT stationery item developed to support adults who continue to learn towards goals such as obtaining certifications and reskilling, by "visualizing" their daily efforts in conjunction with a smartphone app. In the first year since its launch, sales have exceeded 18,000 units, and the number of certifications registered by users as "passed" within the app has surpassed "100 types" (as of the end of April 2026). It is attracting significant attention in the adult reskilling market.

Furthermore, a recent user survey (conducted in May 2026, n=219) showed a high satisfaction rating of 90%, with 68% of respondents stating they are conscious of "working on it every day, even for a short time," and 70% reporting using it "5 days or more per week." This demonstrates its support for the continuous learning habits of "adults who keep learning" with high enthusiasm.

To align with the learning rhythm of these active users, this upgrade doubles the battery life to "14 days" (assuming 2 hours of study per day when using the charging case). Additionally, a new "Black Model" has been added to the lineup, reflecting the quiet passion of adults and stylishly harmonizing with any scene, such as business or study rooms.

KOKUYO will continue to develop products and services that support individual growth and motivation, accompanying "learning" in the 100-year life era.
