Company history

Sangetsu traces back to Sangetsudo, a Nagoya shop opened in 1849 by Hibi Yasuke, a hyogushi — a craftsman who mounted sliding-door panels and hanging scrolls. Four generations later, in April 1953, the family trade was incorporated as Sangetsudo Shoten, with Hibi Kenkichi recorded as founder. Incorporation alone settled nothing: the firm still handled traditional mounting work, and the question of whether to stay in the craft or build a second pillar remained open.

The answer came in April 1960, when the company opened a wallpaper sales division and switched its main business to vinyl wallpaper. This was less a side department than a change of trade. Japanese interiors were still built around fusuma, shoji and plastered walls; vinyl wallpaper had only just arrived from the West, and no established wholesaler had claimed it. Entering an immature market first, as a dedicated wholesaler, was a way to lock up the manufacturers’ distribution and build a national sales network before anyone else could. In 1965 Hibi Kensho became president and launched Elite, the company’s first own-brand wallpaper — a wholesaler taking product planning in-house rather than merely brokering.

In April 1970 the company renamed itself Sangetsu, keeping the old shop name in sound while shedding its craft-trade image, and in June it opened its first showroom in Nagoya — a place where contractors and design offices could show real materials to their own clients, then a rarity in wholesaling. The Tokyo office followed in 1972, and within four years Sangetsu had branches in Tokyo, Fukuoka and Osaka. Japan was starting 1.5–1.8 million homes a year and vinyl wallpaper was becoming standard, so each new branch simply converted into sales. Cushion flooring, added in December 1979, gave the same customers a second product on the same route.

Sangetsu listed on the second section of the Nagoya Stock Exchange in November 1980, moved to Nagoya’s first section in September 1989, and reached the first section of the Tokyo Stock Exchange in December 1996 — a sixteen-year staged listing that bought credit with manufacturers and banks, bargaining weight inside the trade, and the capital to keep opening showrooms and branches. Regional offices followed the money: Sendai in 1982, Sapporo in 1984, Okayama in 1991.

The product line widened on roughly the same clock — curtains in 1981, carpet in 1982, floor tile in 1986, carpet tile in 1988, chair fabric in 1994 — turning a wallpaper wholesaler into a full-line interior supplier. For a contractor or a design office, no one else could cover wall, floor, window and seat from a single order desk, and that breadth was itself the tool for going deeper with each account. A first overseas foothold, Sangetsu America, was set up in 1996, but it stayed small; the business that mattered was domestic.

By the late 1990s Sangetsu held about 50% of Japan’s wallpaper wholesale market, and the reason was structural rather than commercial. Two devices did the work. Showrooms, attached to branches from Nagoya in 1970 outward to Tokyo, Kansai, Kyushu, Tohoku, Hokkaido and Chugoku-Shikoku, let contractors bring clients to the goods instead of selling from a catalogue — cheaper per deal than a manufacturer’s own sales calls, and reproducible by a rival only with a network costing well over a billion yen and years to build.

The sample books were the second. Issued since 1960 and reissued every few years, they became the trade’s de facto catalogue: contractors and architects proposed from them and ordered by part number on the spot. Being listed meant guaranteed distribution for a manufacturer; holding the book meant a sales tool for a contractor. Both sides came to depend on Sangetsu, which is where its pricing power and margins came from — and the several hundred million yen a year the books cost was a fixed burden almost no competitor had the volume to carry.

Holding planning, sourcing, logistics, sales and installation management under one roof kept order lots large and delivery fast. Consolidated revenue settled in the ¥110–130 billion range, reaching $1.3B (¥123bn) in the year to March 2013. It was a comfortable position that also described a ceiling: by the mid-2010s domestic interiors accounted for more than 80% of consolidated sales. Management began to change around the same problem — the Hibi family gave way to career insiders, Sangreen (2005) and Yamada Shomei Lighting (2008) were acquired as adjacent lines, and new distribution centres opened in 2014 and 2016.

Under Yasuda Shosuke, president from 2014, Sangetsu deliberately unsettled the model that had made it rich. In November 2016 it paid roughly $101.1M (¥11bn) for Koroseal Interior Products, the largest US supplier of wallcoverings to non-residential buildings — healthcare, hospitality, education — and followed within a year with the installer Fairtone and Singapore’s Goodrich Global. The cost showed immediately: consolidated operating profit fell 33.5% to ¥5.0 billion in the year to March 2018, the overseas segment lost money for four straight years, and Koroseal alone took about ¥5.9 billion of impairment and related charges in the year to March 2020. Sangetsu held on, replaced Koroseal’s president in 2022, and the North American business turned profitable from the year to March 2023.

In May 2020 the company put a name on the shift: DESIGN 2030, a long-term vision to become a global space-creation company rather than a wholesaler — an explicit exit from the model it had run for seventy years. A space-creation division began operating that June, bundling materials with installation; the three-year BX 2025 plan followed in 2023, with human capital, digital capital, exteriors and overseas as its pillars, alongside a new corporate philosophy in 2024 and the PARCs creative base in Hibiya.

The numbers turned sharply. Revenue rose from ¥132.0 billion in the year to March 2014 to ¥189.9 billion a decade later, and operating profit jumped 2.5-fold to ¥20.3 billion in the year to March 2023 as price revisions took hold and Koroseal recovered. In April 2024 Kondo Yasumasa, a career Mitsubishi Corporation man who had joined Sangetsu only in December 2022, became president — the succession moving one more step outward, from founding family to insider to outsider. He named the one-legged domestic structure as the problem, acquired Singapore’s D’Perception in 2024, and posted record results of $1.3B (¥206bn) in revenue for the year to March 2026. Overseas, though, was still in the red a year earlier: the ceiling has been raised, not removed.
