Isetan Shinjuku Men's Store will remodel and reopen its fourth and fifth floors, which primarily stock business wear, on March 12th. The fourth floor will be reorganized around the concept of "inherited authenticity," while the fifth floor will be reorganized around the concept of "tailored clothing."

The new fourth floor of the Men's Store will be named "International Luxury" and will feature timeless products that stand out from the trends, with the aim of providing products and services of global standards. In addition to the existing Italian Classico Zone, a new Edit Zone featuring British-style items will be added. This floor will strengthen its custom-made offerings to meet diverse customer needs. The bespoke premium tailoring corner will feature new brands, "Londoner" and "TRENZA." The custom-made garments can be tried on and pinned from a fitting, allowing for easy customization and alterations similar to a full custom order. The new fifth floor will be renamed "Business Clothing" and will offer an expanded range of sizes, materials, and styles to suit a variety of occasions. The newly established "House of Tailor" will feature eight Japanese tailors who will express their own unique worldviews, and will also begin offering three original Isetan men's suit models representing Italy, the UK, and the US: "Napoli Classico," "English Drape," and "Authentic American."
