For Sustainable Health-Innovation 2026 – Tokyo Agreement, hosted by Takenaka Corporation, our PAPLUS® Stacking Tumbler Black was adopted as a drink cup for event participants.

For this occasion, the cups were produced in a special edition featuring the COT-Lab® logo—an open innovation hub operated by Takenaka Corporation to foster collaboration among industry, government, and academia—together with laser-engraved participant initials, creating a personalized cup for each guest. Designed not only for use during the event but also to be taken home and used continuously, the cups functioned as personalized, long-lasting corporate gifts designed to be kept and reused.

Rather than being disposable giveaways distributed in large quantities, the cups were intended as personal products participants could feel attached to, proposing value beyond single use. The initiative also contributed to reducing disposable cups at the venue, embodying the event’s sustainability theme through the product itself.

By incorporating the spirit of co-creation and innovation represented by COT-Lab® into the cups, they became more than commemorative items—they became products that allow participants to take part of the dialogue and collaborative experience home with them.

This approach of putting environmental consideration into practice through placemaking and experience design resonates strongly with the philosophy of PAPLUS®.
It is one example of how we pursue products people won’t want to throw away.
