Buying an existing business in Tokyo can be faster and less risky than starting from scratch, but the Japanese M&A market operates on different assumptions than most Western buyers expect. Relationships matter enormously, deal timelines stretch longer, and due diligence surfaces risks that wouldn’t appear on a Western balance sheet. This guide covers where to find deals, how the market works, and what to prioritize in your due diligence process.
The Japanese M&A Market: Size and Structure
Japan is currently experiencing a historic surge in M&A activity, driven primarily by demographic pressure. With an aging population and a shortage of successor owners for small and mid-size businesses, tens of thousands of otherwise profitable companies are expected to change hands over the next decade. The Small and Medium Enterprise Agency estimates that over 600,000 Japanese businesses face closure or sale due to the owner succession problem, a dynamic that creates significant opportunity for buyers who understand how to approach the market.
The market is divided into two broad segments. At the institutional end, large strategic acquisitions are handled by investment banks and the M&A advisory arms of major securities firms like Nomura, Daiwa, and SMBC Nikko. At the SME end, the market is served by specialized business brokers and government-backed matching platforms that have proliferated in response to the succession crisis.
Where to Find Deals
Business Broker Platforms
The dominant online marketplaces for SME acquisitions in Japan are Batonz, M&A Navi, and Tranbi. These platforms list businesses ranging from small restaurants and retail shops to mid-size manufacturing and services companies. Most listings are anonymous at first contact, with full disclosure happening only after a non-disclosure agreement is signed. Listing prices on these platforms range from a few million yen for micro-businesses up to several hundred million yen for established operations.
For buyers based outside Japan who want exposure to international listings that include Japanese businesses, BizBuySell occasionally features Japanese franchise operations and businesses with cross-border appeal, though the depth of Japan-specific listings is limited compared to the domestic platforms. BizBuySell is more useful as a benchmarking tool and for sellers who want to attract international buyers than as a primary search channel for Tokyo SME acquisitions.
Business Brokers and M&A Advisors
Japan’s M&A broker landscape is growing rapidly. Nihon M&A Center is the largest publicly listed M&A broker in Japan and handles thousands of transactions annually, primarily in the 50 million to 3 billion yen range. Strike Co. and M&A Capital Partners are two other major players focused on the SME segment. All three have Tokyo offices and work with both domestic and foreign buyers.
For smaller transactions, the regional banks (chiho ginko) have become active intermediaries. Banks such as Joyo Bank, Chiba Bank, and many others now operate in-house M&A matching services as part of their business support offerings. If you have an existing banking relationship in Japan, your relationship manager is often a useful starting point for off-market introductions.
Due Diligence Considerations in Japan
Financial Records and Tax History
Japanese small businesses often maintain two sets of financial records: the official tax filing (zeimu shinkoku) and internal management accounts. This practice, while declining as tax enforcement tightens, means that the tax returns submitted to the National Tax Agency may significantly understate revenue compared to actual business performance. Buyers should request both the formal tax filings and any internal records, and should be prepared for sellers to be reluctant to share information that might imply unreported income.
Corporate tax returns in Japan are filed with both the national and local tax authorities. Requesting the past three to five years of both returns, along with the accompanying financial statements (taishaku taishohyo and soneki keisan sho), gives you the baseline picture. Any significant discrepancies between reported revenue and bank deposits warrant deeper investigation.
Employee Relationships and Labor Obligations
Japan has strong labor protections, and employees are not easily dismissed even after a change of ownership. In an asset purchase, you are generally not obligated to retain staff, but in a share purchase you inherit all existing employment contracts and obligations. If the business has been underpaying social insurance premiums (nenkin and kenko hoken), those liabilities transfer with the shares. A thorough review of payroll records, social insurance enrollment, and any outstanding labor disputes is essential before closing.
Real Estate and Lease Assignments
If the business occupies leased premises, confirm whether the landlord’s consent is required for a change of ownership or a lease assignment. Many Japanese commercial leases include clauses that prohibit assignment without landlord approval, and some landlords will use a transaction as an opportunity to renegotiate terms or increase the deposit. Sorting this out before signing is far easier than dealing with a lease default after closing.
Permits and Licenses
Many Japanese businesses operate under industry-specific licenses that are tied to the entity or to a named individual. Restaurants need a food hygiene license. Bars need a late-night entertainment license. Construction companies need contractor registrations. Confirm which licenses the target business holds, whether they are transferable in a share sale, and whether a foreign buyer is eligible to hold them. The Food Sanitation Act, the Wind and Amusement Business Act, and the Construction Business Act each have specific requirements that can affect deal structure.
Deal Structure and Pricing
Most SME transactions in Japan are structured as share purchases rather than asset purchases, primarily because asset transfers can trigger significant registration and real property acquisition taxes. Pricing for small businesses typically uses a multiple of EBITDA or net profit, with multiples ranging from 3x to 6x for service businesses and 1x to 3x for capital-intensive or lower-margin operations. Goodwill is rarely separated out as a distinct line item in Japanese valuations.
Seller financing is uncommon. Most transactions are cash at close, which means buyers need access to capital up front. The Japan Finance Corporation (JFC) offers acquisition financing for SME buyers, and some regional banks will provide acquisition loans to buyers with strong profiles and meaningful equity contributions.

Start Your Search the Right Way
Buying a business in Tokyo is a genuine opportunity, particularly in sectors facing ownership succession challenges. The key is patience, local legal counsel, and a realistic understanding of how Japanese sellers approach trust and negotiation. Do not rush the relationship-building stage. The deals that close cleanly in Japan almost always start with a foundation of mutual respect and demonstrated seriousness.
