AAA+

A premium line derived from KATO`’s main men’s line, it launched in 2007. While KATO` centers on basic denim and American casualwear, AAA+ delves into fabric development, treatments, and vintage-derived details, reconstructing past clothing through Hiroshi Kato’s interpretation rather than reproducing it as it was. Unlike the womenswear line GRANDMA MAMA DAUGHTER, the contemporary menswear line 13 ARROW, and the functional casualwear line Le Passe-temps Bleu, it is the top-tier menswear line that places the strongest emphasis on materials and treatments.

AAA+Feminine was established as a women's line derived from AAA+, extending the parent brand's focus on business shoes to women. The brand page presents it as a women's line, centered on loafers, dress shoes, pumps, sandals, and sneakers, and also offering oxfords, mannish styles, rain shoes, and boots. Spanning office, casual, and formal settings, it caters to occasions such as job hunting, commuting, and kindergarten or school enrollment, and is developed as a line responsible for AAA+'s staple footwear for women.
