POCARI SWEAT is a health drink that smoothly replenishes water and electrolytes (ions) lost through sweat, and it is now available in more than 20 countries and regions.

Since its launch in Japan in 1980, Otsuka has continued to study the impact of fluid and electrolyte replenishment on the body. These efforts have uncovered scientific evidence supporting the drink's usefulness not only during perspiration from sports or labor in hot conditions but also in everyday situations, such as during dry winter months or after bathing.

POCARI SWEAT initiated its international expansion in 1982. In July 2025, it was introduced in India. By continuing to address the health challenges that vary by country and region and by taking actions rooted in the unique culture and customs of each area, overseas sales volume has exceeded domestic sales since 2021. As a result, the brand has accelerated its growth as a global brand in recent years.
