SmartHR is a Tokyo-headquartered SaaS company building cloud-based human resources and labor management software tailored to Japanese employment law.
The platform digitises payroll-adjacent workflows that historically consumed weeks of paper-based effort each year, including social insurance enrollments, year-end tax adjustments (nenmatsu chosei), employment contracts, and family-status changes that drive Japanese benefits.
Founded in 2013 by Shoji Miyata, SmartHR has grown into one of the most widely deployed HR cloud products in Japan, serving more than 60,000 customers ranging from small startups to listed enterprises. The company crossed unicorn status in 2021 and was reported at roughly 1.6 billion US dollars in valuation after a 2023 financing round led by KKR alongside existing investors.
SmartHR sits at an interesting intersection of regulatory complexity and product-led growth. Japanese labor law is notoriously paperwork-heavy, with separate filings to the pension office, the health insurance association, the tax office, and the labor standards bureau for what would be a single onboarding event in most countries.
SmartHR digitises and pre-fills these forms, which is why its retention numbers are unusually strong by global SaaS standards. The company is widely expected to file for a domestic JPX listing once market conditions permit.
SmartHR is a useful case study for any founder thinking about Japanese corporate structure choices, because it illustrates the modern Tokyo tech playbook clearly.
KK over GK for venture-backed software. SmartHR is structured as a Kabushiki Kaisha (KK), the joint-stock company form that dominates Japanese venture-backed tech.
Although the simpler Godo Kaisha (GK), an LLC-style vehicle introduced in the 2006 Companies Act reform, has lower ongoing compliance costs and no statutory auditor requirement, KKs remain the default for any company that expects to raise priced equity rounds, issue stock options under the qualified-tax-treatment regime, or eventually list on the Tokyo Stock Exchange.
Japanese venture investors expect a KK term sheet, and the share-class flexibility added by post-2006 reforms makes preferred stock workable.
JPX listing tiers after the 2022 restructure. The Tokyo Stock Exchange replaced its old First Section, Second Section, Mothers, and JASDAQ tiers with three new segments: Prime, Standard, and Growth. Prime is the flagship tier with strict free-float, market-cap, and English-disclosure expectations.
Standard sits in the middle, and Growth is for high-potential but earlier-stage issuers and replaced Mothers. Recent Japanese tech IPOs have spread across Prime (Mercari, freee, Money Forward, Sansan all initially listed on Mothers and migrated up) and Growth.
Founder voting share patterns. Unlike US tech where dual-class structures are routine, Japanese listed companies traditionally operate on one-share-one-vote. Founder control is preserved instead through high pre-IPO ownership and through the use of Class A and Class B common stock arrangements that are reviewed carefully by the JPX.
SmartHR has used preferred share rounds private-side, which will convert at IPO.
Pick a KK (Kabushiki Kaisha) if you expect to raise priced venture rounds, grant Japanese qualified stock options, or list on the JPX. Pick a GK (Godo Kaisha) if you are a foreign parent setting up a wholly-owned operating subsidiary and want lower ongoing compliance and no statutory auditor requirement.
Prime is the top JPX segment. Headline thresholds include a tradable market cap of at least 10 billion yen, at least 800 shareholders, a 35 percent free float, and full English disclosure. Most growth-stage tech firms list on Growth or Standard first and migrate up later, as Mercari, freee, Money Forward, and Sansan all did.
Yes. There is no general foreign-ownership cap on Japanese KKs or GKs. Sector-specific restrictions exist (broadcasting, certain critical infrastructure, defense), and the Foreign Exchange and Foreign Trade Act requires advance or post-investment notification in regulated industries, but for software and SaaS a foreign founder can hold 100 percent of the shares.
Legally yes, since the 2006 Companies Act reform abolished the old 10-million-yen minimum for KKs and 3-million-yen minimum for GKs. In practice 1 million yen is the working floor because below that level bank accounts, supplier credit, and visa applications all become difficult, and 5 million yen is required if a foreign founder also wants a Business Manager visa.
