Wovn Technologies is a Tokyo-headquartered SaaS company that builds website and application localisation infrastructure, helping Japanese organisations make their digital properties multilingual without rebuilding the underlying engineering stack.
Wovn Technologies is a Tokyo-headquartered SaaS company that builds website and application localisation infrastructure, helping Japanese organisations make their digital properties multilingual without rebuilding the underlying engineering stack. The flagship product, WOVN.io, sits as a translation proxy in front of a customer's existing site, ingesting source-language content and delivering localised versions across more than 40 supported languages with fallback machine translation, professional translation workflows, and term-glossary management.
Founded in 2014 by Jeff Sandford and Hiroshi Hayashi, Wovn has grown into one of Japan's most-deployed localisation platforms, with customers spanning large Japanese corporates, government agencies, and travel and retail brands preparing for inbound tourism rebounds. A companion product, WOVN.app, extends the same localisation logic to native mobile applications.
The company has raised multiple rounds from Japanese institutional investors and corporate strategic partners and is positioned at a useful intersection of two Japanese economic priorities: outbound expansion of Japanese SaaS into international markets, and inbound tourism and immigration that drives demand for multilingual public-facing services. Wovn has not yet listed publicly but operates the same KK governance template as the broader Tokyo SaaS cohort.

Estonia e-Residency play
Wovn Technologies illustrates the corporate-structure choices that face a Tokyo SaaS company with a non-Japanese co-founder, which is a useful angle for any foreign founder considering Japan as a base.

Estonia e-Residency play
**KK as the venture-default form.** Wovn is a Kabushiki Kaisha. The KK is the standard Japanese venture form because it is the only structure that can list on the JPX, the form Japanese venture investors require on priced-round term sheets, and the form that supports the Japanese qualified stock-option regime. The GK (Godo Kaisha), although faster and cheaper to incorporate, is generally not workable as a standalone venture-financed company.

Parent-subsidiary layout
**Why some foreign founders pick a GK initially.** A non-Japanese founder setting up a small operating subsidiary often picks a GK as the first vehicle because GK incorporation has no notarisation requirement for the articles, no kansayaku obligation, and lower registration tax. The trade-off is that GKs cannot list and look unusual to domestic Japanese venture investors, so any company on a Wovn-style trajectory should plan to convert from GK to KK before the first priced round, or simply incorporate as a KK from day one.

Share class engineering
**Founder voting in a one-share-one-vote market.** Japanese listing rules generally disfavour US-style dual-class voting shares, so founders Jeff Sandford and Hiroshi Hayashi preserve influence through pre-IPO ownership and board composition rather than super-voting stock. This is one of the structural reasons foreign founders sometimes consider a Singapore or Delaware topco above their Japanese subsidiary, but it also means clean cap-table mechanics and a straightforward shareholder register, which institutional Japanese investors prefer.
Replicate Wovn Technologies's structure in 4 steps
The formation playbook, distilled from how this company was actually set up.
German entity type
Incorporate a KK at the Tokyo Legal Affairs Bureau. Notarise the articles of incorporation, deposit at least 1 million yen of paid-in capital (5 million for a Business Manager visa), and register the company seal.
Adopt the company-with-audit-committee governance model
Adopt the company-with-audit-committee governance model from incorporation, which aligns with future JPX expectations and modern investor norms.
Estonia e-Residency play
Register at least one Japanese-resident representative director. A foreign co-founder may serve in this role with a Business Manager visa, ideally paired with a Japanese co-founder or operator who can sign domestic agreements without translation friction.
Tax strategy
Reserve a Japanese qualified stock-option (zeisei tekikaku) pool so future hires receive deferred-tax treatment until exercise and sale.

Frequently Asked Questions
Should a foreign-founded Tokyo SaaS like Wovn pick KK or GK?
Pick KK if you expect priced venture rounds, qualified stock options, or a JPX listing. Pick GK only if you are running a wholly-owned operating subsidiary of a foreign parent and want lower ongoing compliance and faster, cheaper incorporation. GKs cannot list, cannot use the same share-class flexibility, and look unusual to Japanese venture investors, so any company with public-market or large-priced-round ambitions should incorporate as a KK from day one.
What does it take to list on JPX Prime?
Prime is the top JPX tier, requiring a tradable market cap of at least 10 billion yen, at least 800 shareholders, a 35 percent free float, English-language disclosure of material announcements, and adoption of the audit-committee or three-committees governance model. Most growth-stage tech firms list on Growth (the post-2022 successor to Mothers) first and migrate up later, as Mercari, freee, Money Forward, and Sansan all did.
Are there foreign-shareholder restrictions on Japanese SaaS companies?
For mainstream consumer and B2B SaaS there is no general foreign-shareholder cap. The Foreign Exchange and Foreign Trade Act requires pre-notification for large stakes in regulated sectors such as broadcasting, defense, certain critical infrastructure, and IT systems handling national-security data, but routine localisation, productivity, and CRM software is unrestricted, and foreign founders can hold 100 percent of a Japanese KK.
How was the minimum-capital rule for a KK reformed?
The 2006 Companies Act abolished the previous 10-million-yen minimum for KKs and the 3-million-yen minimum for GKs. The legal floor today is 1 yen of paid-in capital, although in practice 1 million yen is the working minimum to open bank accounts and sign supplier contracts, and 5 million yen is required for a foreign founder to apply for a Business Manager visa.
