From Father to Daughter: A Father’s Day Campaign Offering 'Thank You for Being My Dad'

PlayS Co., Ltd. (Plays, Minato-ku, Tokyo) announces the launch of the 'From Dad to Daughter: Thank You for Being My Dad' Father’s Day campaign in collaboration with the trade-in service 'doop' (operated by SLONE Inc.), running from Tuesday, June 16 to Tuesday, June 30, 2026.

Father’s Day, but for the Daughter?

This campaign allows customers to trade in unused household items through doop when purchasing PlayS absorbent underwear, effectively reducing the net cost of the product.

For example, when a father sells his unused belongings, the campaign flips the script on Father’s Day by using the proceeds for his daughter’s needs. The goal is to create a moment where fathers, even if they don’t fully understand, can emotionally support their daughters through sensitive issues like menstruation, vaginal discharge, or light incontinence.

Comment from Daisuke Sakagami, PlayS Developer and Business Lead

"As a father myself, I’ve noticed that while menstruation is often discussed between mothers and daughters, more fathers are starting to think, 'I may not fully understand, but I want to help.' Through this trade-in initiative, I hope families can begin to include fathers in conversations about menstruation—if the daughter is comfortable with it."
