FOUR SIS & CO.

What FOUR SIS & CO. does

FOUR SIS & CO. (株式会社フォーシスアンドカンパニー) is a Tokyo-headquartered, privately held Japanese bridal services group founded in April 1995 and operating as a wholly owned subsidiary of ㈱コンサバティブホールディングス. The company provides an integrated wedding platform spanning costume (rental and sale of original and international designer dresses under brands such as FOURSIS BRIDE, Ameris, and Affectionns by Taki), bridal beauty (D'colle THE BEAUTY / Four Sis Beauty, with 6,000+ annual cases), photography and video (Four Sis Mediage, Photo Mariage, and the PHOTO BRIDGE web-based photo-selection service with ~60 locations), flowers and decoration (Four Sis Flower), Okinawa/Hawaii resort weddings (Wedding Lounge), B2B wedding consulting for hotels and venues, wine and champagne import (Vinorum), and ancillary technology services including bridal credit via APLUS, foreign currency exchange machines, and Web3 game-asset distribution. Underlying operations are managed through a proprietary customer and inventory platform called Guardian (ガーディアン), recognized in 2014 as an IT Management Practice Enterprise.

The go-to-market model is built on long-standing B2B partnerships with hotels and wedding venues across Japan, into which FOUR SIS embeds showrooms and accepts customer referrals rather than relying on mass advertising; partner venues reportedly channel around 2,500 weddings per year with 95% of couples selecting FOUR SIS for attire. The company complements this with approximately 60 directly operated retail showrooms under multiple brand banners (MAISON de FOURSIS, Dress DISTRICT, CLASENCERE, FOURSIS GLOBAL LINE, MODE MARIEE) covering every major Japanese region from Hokkaido-adjacent Tohoku through Kansai, Chugoku/Shikoku, Kyushu, and Okinawa. The organization employs 570 staff as of May 2026, has progressively internalized cleaning (2015 acquisition), video production (2017/2021), entertainment (2018/2022), and wine (2022) via M&A, and celebrated its 30th anniversary in 2024 with a logo refresh and headquarters relocation to Shibuya Sakura Stage SAKURA Tower.

Monetization is primarily through one-time wedding-costume sales/rentals and per-event professional services fees (beauty, photography, flowers, consulting), supplemented by B2B wholesale (wine), transaction fees (bridal credit), and distribution (foreign currency exchange, Web3 assets). Customer concentration is structurally moderate-to-high because demand flows through a finite pool of partner hotel and venue groups, although the end-consumer base is large and fragmented. The company is privately held with registered capital of ¥50 million, no institutional venture or public-market backing, and full ownership consolidated under its holding-company parent.
