About Notary Public
In Japan, a Notary Public (公証人, kōshōnin) is a government-appointed legal professional who prepares and certifies notarized deeds and authenticates certain documents. Their role is to prevent disputes by ensuring documents are properly executed, identities are verified, and legal formalities are met.
You may need a Notary Public in Tokyo when you’re creating a notarized deed (公正証書), authenticating a private document for use abroad, preparing a will in notarized form, or formalizing agreements such as loans or certain settlement arrangements. Many people also use notary services during company setup processes (for example, notarization of articles of incorporation, depending on the company structure and current legal requirements).
Average cost in Tokyo: Notary fees in Japan are generally governed by a national fee schedule, so pricing is often standardized rather than “market-rate.” In practice, many simple certifications may cost from a few thousand yen, while more complex notarized deeds can be tens of thousands of yen or more. Exact totals depend on document type, amount involved, number of pages/copies, and any required add-ons.
Licensing/certification: Notaries in Japan are appointed through the Ministry of Justice framework (exact appointment details vary and are not always published per office). Many notaries have extensive legal backgrounds, but individual biographies are not consistently disclosed publicly by each office.

Cost of Hiring a Notary Public in Tokyo
In Tokyo, notary pricing is typically driven by a national fee schedule rather than a fully competitive market rate. That’s good for predictability, but the “final cost” can still vary significantly depending on what you’re notarizing and how complex the deed is.
Average price range: Many straightforward certifications can start around a few thousand yen. More involved notarized deeds (for example, agreements tied to monetary amounts, multiple parties, or extensive drafting) can rise into the tens of thousands of yen or more. If your matter involves corporate documentation or high-value transactions, costs may increase accordingly.
Emergency pricing: 24/7 service is not standard for notary offices in Tokyo. If expedited handling is possible, it depends on scheduling and office policy—this is often Not publicly stated and should be confirmed directly.
What affects cost
- Document type (authentication vs notarized deed vs will in notarized form)
- Amount of money involved in the agreement (where applicable)
- Number of parties and required identity checks
- Drafting complexity and time required for review
- Page count, attachments, and number of certified copies
- Translation needs (if required; availability varies / depends)

Final Recommendation
If you want the most convenient in-person process, choose a notary office closest to your daily commute—Shinjuku, Shibuya, Ginza, and Ikebukuro offices are commonly sought simply because they’re anchored to major transit hubs.
For business-heavy agreements and formalized deeds, a central area office like Ginza Notary Office or Tokyo Notary Office can be a practical fit. If you’re cost-sensitive, focus less on “shopping prices” (fees are largely standardized) and more on reducing avoidable add-ons: bring complete documents, confirm requirements in advance, and minimize last-minute revisions.
