Company profile
researched Aug 2026one nova is a Japanese direct-to-consumer underwear and innerwear brand operated by 株式会社ONE NOVA (One Nova Co., Ltd.), headquartered in Setagaya-ku, Tokyo. The brand positions itself as a problem-solving underwear line, aiming to eliminate common discomforts such as odor, stuffiness, constriction, itchiness and slipping, and to deliver a "noiseless" wearing experience. Its catalogue spans wireless and tube bras, bra-integrated T-shirts, camisoles and tanks, women's bikinis and thongs, high-waist styles, and men's and unisex boxer briefs and boxer shorts, with prices on its own store ranging from roughly ¥3,850 for briefs to ¥8,850 for long-sleeve bra T-shirts.
The company's core asset is nova wool®, an in-house material built mainly on natural inputs including merino wool and wood pulp. It is described as retaining merino wool's temperature and humidity regulation, breathability and odor resistance, adding deodorizing and antibacterial function, while addressing wool's typical weaknesses of pilling and tearing. Product design pairs this material with patterns developed separately for male and female body characteristics to minimize skin stress. The company also runs sponge, an absorbent-underwear brand covering both urine and menstrual leakage and marketed to all age groups.
Inclusivity of fit is part of the product strategy: sizes run from XS to XXXL and a portion of the range is offered as unisex, framed as reducing situations where body shape or gender limits comfortable choices. The company describes itself as unusually transparent about production, publishing the stages of its manufacturing process; earlier coverage described it as selling fair-trade organic-cotton men's boxer shorts under the tagline "the world's most transparent underwear."
Founding story
The company was established in December 2017 as a student venture; Forbes identifies cofounders Taiga Takayama and Lilian Kanemaru, then students at Keio University, and notes the company was involved across fabric making, dyeing, manufacturing and packaging. Taiga Takayama (高山泰歌) is the representative director.
Business model
Consumer product brand: one nova develops proprietary fabric, has garments manufactured, and sells them under its own brands (one nova and sponge) primarily through its own e-commerce site, supplemented by pop-up retail and stockists such as the lingerie brand EMILY WEEK.
Revenue comes from direct-to-consumer product sales at fixed unit prices on the brand's online store, with promotional discounting (for example sale pricing and seasonal campaigns) and volume discounts; free size exchange is offered within 14 days of purchase even after wear.
Traction
A crowdfunding campaign raised approximately ¥23 million from backers in more than 60 countries before general Japanese retail sales began in December 2020. The one nova product line launched in July 2018 and sponge in July 2021; the brand marked its eighth anniversary with a commemorative tenugui. Preqin describes market presence in Japan, North America and parts of Europe.
Latest developments
Recent brand activity includes a limited "Maroon" colorway across three staple styles (3D Wireless Bra, Full Cover Bikini, Flat Boxer Brief), the launch of the Ribbed 3D Bra T-shirt combining a merino-blend material with ribbed fabric and cup-based sizing, and pop-ups with lingerie brand EMILY WEEK in Yokohama, Nagoya and its online store where the new 3D Wireless Tube Bra and Ribbed 3D Bra T-shirt can be tried.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
A small, venture-backed Japanese innerwear startup competing on material science and comfort claims rather than scale; databases classify it as a research-and-development-oriented D2C fashion/retail company with fewer than about ten employees, and it has been recognized in Forbes' 30 Under 30 Asia Retail & Ecommerce 2019 list.
Ownership of an in-house merino-wool-based material (nova wool®) positioned to fix wool's durability drawbacks, a wide XS–XXXL and unisex size range, publication of production-process details as a transparency claim, and an adjacent absorbent-underwear brand (sponge).
Technology
nova wool® is a proprietary textile derived mainly from natural materials such as merino wool and wood pulp, engineered for deodorizing/antibacterial performance and temperature and humidity regulation while reducing pilling and tearing; the brand combines it with pattern engineering intended to eliminate slipping, chafing and itch.
Go-to-market
Primarily online D2C through onenova.jp, complemented by physical exposure via pop-up stores (a first pop-up at JR Nagoya Takashimaya in November 2021) and pop-ups/stocking at EMILY WEEK's Yokohama and Nagoya stores and its e-commerce site. Earlier launches used crowdfunding, and the brand has run collaboration products, including a gender-neutral underwear line tied to the RADIO EVA 15th anniversary Evangelion project.
Everyday consumers buying innerwear in Japan, including men and women across a wide size range (XS–XXXL) and buyers of unisex items; sponge targets users needing absorbent underwear for urine or menstrual leakage across age groups.
Geography
Headquartered in Tokyo (Setagaya-ku, Tamagawa), with a Kanagawa (Yamato-shi) location also recorded; sales focused on Japan, with stated overseas expansion plans and reported presence in North America and parts of Europe.
History
Incorporated in December 2017 as a student startup. The One Nova underwear line launched in July 2018, initially built around men's boxer shorts marketed for their transparency of production. Product and marketing milestones followed in 2019, including a new-color launch, trial PayPay payments via LINE@, and a limited embroidered "Reiwa" edition tied to the era change. After a crowdfunding campaign spanning more than 60 countries, general sales in Japan began in December 2020. The sponge absorbent-underwear brand launched in July 2021, followed by a seed financing in 2021 and a first pop-up store at JR Nagoya Takashimaya in November 2021. In 2023 the brand released an Evangelion-themed gender-neutral underwear collaboration, and it has since expanded into bras, bra tops and camisoles built on nova wool®.
Risks & controversies
Public records show inconsistent basic company data across third-party databases, including differing headquarters (Tokyo versus Yamato-shi, Kanagawa) and conflicting leadership attribution, with Preqin naming a CEO different from the representative director listed in Japanese corporate databases.
