About I AM BEAMS
I AM BEAMS is a personal book series featuring BEAMS staff members, each capturing an individual's distinct aesthetic — from the collections and cultural references that shape their creativity to the fashion and lifestyle choices that define their look. Since launching in 2023, ten volumes have been released, each spotlighting a different staff member.
Vol.11: KATO

The eleventh volume focuses on Tadayuki Kato, who has served as BEAMS menswear casual buyer since 2012 and launched his own brand SSZ in 2016 as its director. Alongside his work in fashion, Kato also tends to a vegetable farm in Kamakura as the fourth-generation operator of "Kato Farm," dividing his days between fashion and agriculture.
The book explores Kato's style and the thinking behind it through an extensive archive of clothing, products, tools, personal belongings, and documents he has accumulated over the years — items he has collected, created, and never let go of. Rather than being guided by vintage status, rarity, or market value, Kato's archive reflects a simple standard: choosing what he genuinely finds good.






Rather than a collection book or memoir, KATO is framed as a document that brings to the surface Kato's aesthetic sensibility and the continuity of his choices through objects — aimed at fashion and culture enthusiasts, and anyone thinking about what developing a personal style really means.
