Event: "Fun Experiment: Toilet no Kami-sama"

    The event title plays on the Japanese pop song "Toilet no Kami-sama," where "Kami-sama" translates to "God" in Japanese, while "Kami" also means "paper," often referring to toilet paper. The JS Training Center hosted a "Fun Experiment: Toilet no Kami-sama" event on Wednesday, July 30. During this event, JS instructors provided an engaging and easy-to-understand explanation of sewerage. The children participated in an experiment to observe whether items that can be flushed down the toilet dissolve in water. Thank you for joining us for this fun and educational experience!
