adidas Japan just opened the Sportswear Fall Collection campaign — “go your own way” as the line, with Sekiguchi Mendy and actor Seto Riko on the visuals and in on the styling.

Today’s PR TIMES release (October 2, 10:00 JST) leans on Stadium wash-denim jackets and pants, glossy tricot track tops, velour, and faux-leather pieces that push Three Stripes and tracksuit culture into layered townwear. Both talent names helped style their looks; the brand is rolling more cast styling across adidas social and the online shop.

The collection is already live at adidas stores, adidas.jp, and select retailers — this post is the campaign announce, not a future drop date.
