<sup>art-31 · https://japanlaw.org/ja/civil-code/art-31 · https://japanlaw.org/l/129AC0000000089/art-31</sup>

    **第一項**  前条第一項の規定により失踪の宣告を受けた者は同項の期間が満了した時に、同条第二項の規定により失踪の宣告を受けた者はその危難が去った時に、死亡したものとみなす。
    <sup>art-31/par-1 · https://japanlaw.org/ja/civil-code/art-31/par-1 · https://japanlaw.org/l/129AC0000000089/art-31/par-1</sup>
    A person subject to a declaration of presumed death pursuant to the provisions of paragraph (1) of the preceding Article is deemed to have died when the period of time referred to in that paragraph ended, and a person subject to a declaration of presumed death pursuant to the provisions of paragraph (2) of that Article is deemed to have died when that danger had passed.

<sup>art-32 · https://japanlaw.org/ja/civil-code/art-32 · https://japanlaw.org/l/129AC0000000089/art-32</sup>

    **第一項**  失踪者が生存すること又は前条に規定する時と異なる時に死亡したことの証明があったときは、家庭裁判所は、本人又は利害関係人の請求により、失踪の宣告を取り消さなければならない。この場合において、その取消しは、失踪の宣告後その取消し前に善意でした行為の効力に影響を及ぼさない。
    <sup>art-32/par-1 · https://japanlaw.org/ja/civil-code/art-32/par-1 · https://japanlaw.org/l/129AC0000000089/art-32/par-1</sup>
    Having received proof that a person presumed dead is alive or they died at a time that is different from the time provided for in the preceding Article, the family court must revoke the declaration of presumed death, at the request of the person themselves or an interested party. In this case, the revocation does not affect the validity of any act performed in good faith after the declaration of presumed death but before its revocation.
    <sup>Ministry of Justice translation — Japanese Law Translation Database System</sup>

    **第二項**  失踪の宣告によって財産を得た者は、その取消しによって権利を失う。ただし、現に利益を受けている限度においてのみ、その財産を返還する義務を負う。
    <sup>art-32/par-2 · https://japanlaw.org/ja/civil-code/art-32/par-2 · https://japanlaw.org/l/129AC0000000089/art-32/par-2</sup>
    A person who has acquired property due to a declaration of presumed death loses the rights in question due to its revocation; provided, however, that the person has the obligation to return that property only to the extent that the person has actually been enriched.

<sup>art-32-2 · https://japanlaw.org/ja/civil-code/art-32-2 · https://japanlaw.org/l/129AC0000000089/art-32-2</sup>

    **第一項**  数人の者が死亡した場合において、そのうちの一人が他の者の死亡後になお生存していたことが明らかでないときは、これらの者は、同時に死亡したものと推定する。
    <sup>art-32-2/par-1 · https://japanlaw.org/ja/civil-code/art-32-2/par-1 · https://japanlaw.org/l/129AC0000000089/art-32-2/par-1</sup>
    If more than one person dies and it is unclear whether one of them was still alive after the death of another, it is presumed that they all died at the same time.
