Daio Paper announced Attento Gokuusu Kyusui Pants and Smart Boxer Pants on September 9, 2026, with a nationwide Japanese launch planned for October 21. Both are disposable absorbent underwear designed for small leaks, including leakage with coughing or sneezing and dribbling after using the toilet. The company lists an absorption capacity of 140 ml for each style.
The pink-beige Gokuusu Kyusui Pants were developed with Wacoal, drawing on its Human Science Research Center. Daio describes a thin absorbent core, a line shaped to fit the buttocks and adjusted elastic intended to keep the silhouette compact while providing rear coverage. It says the development took six years. Smart Boxer Pants use a low-rise boxer cut and a light-grey-and-white design, presented for use regardless of gender. Both products are offered in four-piece M and L packs. M covers a waist of 60–95 cm; the L range is 80–110 cm for Gokuusu Kyusui Pants and 80–125 cm for Smart Boxer Pants.
