'Netsusama Sheet' Participates in Niconico Chokaigi for the First Time! 'Netsusama Sheet Cooling Dojo' Booth Offering a 'Cooling Buff' Experience to Cool Gamers' Enthusiasm Opens April 25-26, 2026 at Makuhari Messe

Kobayashi Pharmaceutical Co., Ltd. (Headquarters: Osaka City, President: Yoshikazu Toyoda) will exhibit a booth for the first time under its cooling sheet brand "Netsusama Sheet" at "Niconico Chokaigi 2026," one of Japan's largest subculture events, held at Makuhari Messe on Saturday, April 25, and Sunday, April 26, 2026. Under the concept of "Turn enthusiasm into a cool score," this exhibition proposes a new use case for the product as "cooling immersive gear" that feels good not only when having a fever but also when enthusiastically immersing oneself in games, studying, or creative work. ## "Netsusama Sheet" has been popular for many years as a product that supports "nursing care during fevers" at home. By exhibiting at "Niconico Chokaigi," where about 70% of visitors are youth in their 20s or younger, the goal is to create a space where young people who want to immerse themselves in studying, working, or hobbies like gaming can experience the compatibility between the pleasant "refreshing feeling" of cooling their foreheads and the time of "concentration" when immersing themselves in something. ## 1.

By equipping the Netsusama Sheet on their foreheads and challenging the games in a cool, refreshed state, the sense of immersion in the booth experience is heightened. 2. Trust Your Instincts!

Visitors will receive a "Netsusama-kun Original Sticker." Through play, you can experience the fun of "immersing yourself in a game in a cool and comfortable environment." 3. Refresh Your Eyes in the Cool Down Area Near the exit, a refresh zone will be set up to provide comfortable resting time for eyes that have been continuously used in matches or creative activities.
