Japan’s trust law

How Japan’s Trust Act of 2006 modernised a civil-law trust statute with self-declared, purpose and limited-liability trusts, alongside a separate law for trust businesses and growing use of family trusts.

Education, not legal advice. Trust law changes from country to country and state to state, and the right structure depends on your situation. Anything you sign should be drafted or reviewed by a qualified lawyer where you live.

The lean path

The cheapest, lowest-tax, simplest and most private route the law allows, best first. Each step names the rule it rests on and the condition that keeps it lawful.

  1. A family trust with a relative as trustee avoids trust-company fees, since the Trust Business Act generally does not apply to non-business trustees. Catch: the trustee still files a trust statement (shintaku no keisansho) with the tax office by 31 January where required.
  2. Name the settlor as first beneficiary (a self-benefit trust): no one acquires a beneficial interest without consideration, so no gift tax arises at setup. Catch: gift or inheritance tax applies when another person later acquires the interest without paying for it.
  3. Annual gifts within the ¥1.1 million basic deduction per recipient pay no gift tax under calendar-year taxation. Catch: the education-fund gift trust exemption ended on 31 March 2026, so new contributions no longer qualify.
  4. A specified disability support trust lets a qualifying disabled resident receive up to ¥60 million in trust free of gift tax, or ¥30 million for other qualifying persons. Catch: it runs through a trust company or bank, which forwards the required tax declaration.
  5. A self-declared trust needs no counterparty but takes effect only by notarial deed or similar document, or certified-date notice to the beneficiary (Trust Act art. 4(3)). Catch: it ends if the trustee holds the entire beneficial interest for one continuous year (art. 163(ii)).

Wonder

  1. How can a person be the settlor and the trustee of the same trust?
  2. Why might a statute allow trusts with no beneficiary but limit how long they last?
  3. Why might a family member, rather than a trust company, act as trustee?

  1. Japan’s current Trust Act (Act No. 108 of 2006) was promulgated on 15 December 2006 and came into force on 30 September 2007, replacing the Trust Act of 1922. A trust can be created by contract, by will, or by a declaration by the settlor (Article 3). As elsewhere, the settlor creates and funds the trust, the trustee holds and manages the property, and the beneficiary holds the beneficial interest. Trust property is kept apart from the trustee’s own property. This lesson describes the law and does not recommend any structure.
  2. The 2006 Act allows a self-declared trust (jiko shintaku), in which a person declares that they will hold specified property as trustee for others (Article 3(iii)). To guard against abuse, such a trust takes effect only when made by notarial deed or similar document, or when the beneficiary is notified by a document with a certified date (Article 4(3)). Under the Act’s supplementary provisions, this method became available one year later, from 30 September 2008.
  3. A trust ends if the trustee holds the entire beneficial interest for one continuous year (Article 163(ii)), consistent with the general rule that when the sole trustee is the sole beneficiary, the trust cannot continue. So a self-declared trust must benefit someone other than, or in addition to, the trustee.
  4. The Act also allows trusts with no beneficiary, that is purpose trusts (Articles 258 onward). They may be created only by contract or will, not by self-declaration, and may last no more than 20 years (Article 259). Until a separate law provides otherwise, their trustees are limited to corporations meeting requirements set by Cabinet Order. A limited-liability trust (gentei sekinin shintaku), under Articles 216 onward, takes effect as such only when registered, and the trustee’s liability for trust debts is limited to the trust property.
  5. Professional trustees are regulated by the Trust Business Act (Act No. 154 of 2004), which replaced the Trust Business Act of 1922. A company carrying on trust business needs a licence from the Prime Minister (Article 3), with the work delegated to the Financial Services Agency; a company offering only administration-type trust business may register instead (Article 7). Banks and other financial institutions carry on trust business under a separate act of 1943 on concurrent operation of trust business.
  6. In family trusts, a family member, not a trust company, acts as trustee, often managing an older relative’s home or savings in case the relative’s capacity declines. Because such a trustee does not act as a business, the Trust Business Act generally does not apply. Practitioners often call these civil trusts (minji shintaku); the term kazoku shintaku (family trust) is a registered trademark of a practitioners’ association. Japan’s ageing population is often cited as a reason for their use, but no official count of family trusts was found.

Key facts

  • A trust ends if the trustee holds the entire beneficial interest for one continuous year (Article 163(ii)).
  • Trusts with no beneficiary may be created only by contract or will and may last no more than 20 years (Articles 258 and 259).
  • A limited-liability trust must be registered, and the trustee’s liability for trust debts is then limited to the trust property.
