As part of our initiative to become "the most loved by the community," we are collaborating with all 47 prefectures and Otsuka Pharmaceutical Co., Ltd. (hereinafter referred to as Otsuka Pharmaceutical) to broadcast heatstroke prevention awareness videos unique to each local government on the in-store digital signage "FamilyMart TV" starting June 30, 2026 (Tue). Additionally, at "FamilyMart Kodomo Shokudo" (children's cafeterias) held in July and August, we will host awareness events for parents and children utilizing a heatstroke prevention awareness video that collaborates the anime "Cells at Work" with "Pocari Sweat."

Heatstroke Prevention at FamilyMart! Collaboration with Otsuka Pharmaceutical and Local Governments to Broadcast Awareness Videos on Over 10,000 Digital Signages Nationwide

FamilyMart is disseminating information in collaboration with Otsuka Pharmaceutical and each prefecture to coincide with the period when the risk of heatstroke increases. This year, we will broadcast unique awareness videos (15 seconds) for each prefecture on the digital signage "FamilyMart TV" installed in stores nationwide, issuing warnings about heatstroke through video and audio.

Furthermore, in stores without digital signage, we will also encourage awareness of heatstroke from the sales floor by displaying in-store show cards and other materials.

- Original Fan Making We will hold a workshop to create your own "Heatstroke Prevention Fan." Through experiences such as applying event-exclusive stickers and drawing summer goals or illustrations, participants will increase their interest in heatstroke prevention while having fun.

First Collaboration with FamilyMart's App "FamiPay"

This year, in addition to the in-store digital signage "FamilyMart TV" and sales floors, we will also issue heatstroke warnings within FamilyMart's app "FamiPay."

We will deliver information that fits into customers' daily lives not only to those who visit our stores but also to customers who are not physically present, through "FamiPay."

The Meaning Behind "Ichiban Challenge"

FamilyMart will celebrate its 45th anniversary in September 2026.

To remain a presence chosen as "Ichiban" (the best/number one) by our customers, beyond the framework of a convenience store, in response to the changing times, we have set "Ichiban Challenge: Creating Many of Your 'Ichiban'" as our new slogan.

Under this slogan, we will continue to take on the biggest challenges in FamilyMart's history, based on eight fields: "Delicious," "A Little More Value," "Exciting and Fun," "Discover Something Wonderful," "Innovative and Cutting-Edge," "Environmentally Friendly," "A Place to Want to Work," and "Loved by the Community."
