From January 20th to February 1st, Isetan Shinjuku Men's will open a limited-time shop in the promotional space on the first floor in collaboration with Kinashi Cycle, a bicycle shop run by Sakuzo Kinashi, father of entertainer Noritake Kinashi. Since its founding in Soshigaya-Okura, Tokyo in 1961, Kinashi Cycle has maintained its traditional "local bicycle shop" style. While also operating its own online shopping site, it also sells items in collaboration with fashion brands. The shop will offer in-store exclusives and pre-sale items created in collaboration with the men's department, as well as original products available on the site. A cap (5,300 yen including tax) featuring the "ISETAN × KINASHI CYCLE" logo will be produced and sold exclusively for this limited-time shop in collaboration with Isetan Men's, Kinashi Cycle, STARTER, and override. Other limited edition items on sale include "Tezuka Fujio" T-shirts (3,900 yen including tax), which are a fusion of the works of Osamu Tezuka and Fujio Akatsuka, and bicycle key chains (250 yen including tax).

In addition, the venue will be selling advance sales of items created as a collaboration between Kinashi Cycle and CABANE de ZUCCa, including a hoodie (20,520 yen including tax), a broadcloth shirt (19,440 yen including tax), a T-shirt (8,640 yen including tax), denim pants (30,240 yen including tax), and a 2-way tote bag. Original Kinashi Cycle products on sale include a Kinashi Cycle x TIMEX watch (15,120 yen including tax), a nano・universe down vest (29,800 yen including tax), a PORTER body bag (20,000 yen including tax), and a DEMITA tumbler (1,500 yen including tax). A buyer at Isetan Men's commented on the initiative, "By teaming up, Kinashi Cycle and Isetan Men's hope to cultivate each other's different customer bases. Kinashi Cycle usually only sells on its online shopping site, so this is an opportunity to understand the interests of customers in the real world, and we hope it will lead to future product development for both companies."
