①The expenses required for the submission, delivery and custody of property (excluding expenses required by a person who possessed another person's thing by mistake) are borne by the person who lost the property and receives its return, or by a person who acquires ownership of the property under the provisions of Article 240 of the Civil Code (including the case where it applies mutatis mutandis under Article 3; the same applies hereinafter) or Article 241 of the Civil Code, or under the provisions of Article 32, paragraph (1), and takes it over.

②The provisions of Articles 295 through 302 of the Civil Code apply to the expenses referred to in the preceding paragraph.

①A person who lost property (excluding a thing of another person possessed by mistake) and receives its return must pay the finder a reward in an amount equivalent to 5 percent or more and 20 percent or less of the value of that property (for property sold under Article 9, paragraph (1) or (2) or Article 20, paragraph (1) or (2), the amount of the proceeds of that sale).

②If there is a facility occupant that received delivery of the property, the person who lost the property referred to in the preceding paragraph must, notwithstanding that paragraph, pay each of the finder and that facility occupant a reward in an amount equal to one half of the amount prescribed in that paragraph.

③The national government, local governments, incorporated administrative agencies (meaning incorporated administrative agencies prescribed in Article 2, paragraph (1) of the Act on General Rules for Incorporated Administrative Agencies (Act No. 103 of 1999)), local incorporated administrative agencies (meaning local incorporated administrative agencies prescribed in Article 2, paragraph (1) of the Local Independent Administrative Agency Act (Act No. 118 of 2003)) and other public juridical persons may not claim the rewards referred to in the preceding two paragraphs.

The expenses referred to in Article 27, paragraph (1) and the reward referred to in paragraph (1) or (2) of the preceding Article may not be claimed once one month has elapsed after the property was returned to the person who lost it.

A finder (including another person prescribed in the proviso to Article 241 of the Civil Code) may, by declaring in advance to the chief of a police station (or, for a finder prescribed in Article 4, paragraph (2), the facility occupant) that the finder waives all rights concerning the property, be released from the obligation to reimburse the expenses referred to in Article 27, paragraph (1).

A person who lost property may, by waiving the rights the person holds in the property, be released from the obligation to reimburse the expenses referred to in Article 27, paragraph (1) and the obligation to pay the reward referred to in Article 28, paragraph (1) or (2).

①When all persons who lost the property have waived the rights they hold in the property, the finder acquires ownership of that property; provided, however, that a buried thing prescribed in the proviso to Article 241 of the Civil Code is governed by the same rules as the proviso to that Article.

②A person who acquires ownership of property under the provisions of the preceding paragraph may waive the right so acquired and thereby be released from the obligation to reimburse the expenses referred to in Article 27, paragraph (1).

When a finder prescribed in Article 4, paragraph (2) has, under Article 30 or paragraph (2) of the preceding Article, waived rights in the property that the finder delivered, or has lost rights in it under the following Article by falling under item (iii) of that Article, the facility occupant who received the delivery is deemed to be the finder, and the provisions of Article 240 of the Civil Code, Article 30, and the main clause of paragraph (1) and paragraph (2) of the preceding Article apply. In this case, the phrase "chief of a police station (or, for a finder prescribed in Article 4, paragraph (2), the facility occupant)" in Article 30 is deemed to be replaced with "chief of a police station".

A person falling under any of the following items loses, with respect to the property of which the person made a finding or that the person received by delivery, the right to claim the expenses referred to in Article 27, paragraph (1) and the reward referred to in Article 28, paragraph (1) or (2), and the right to acquire ownership under the provisions of Article 240 or 241 of the Civil Code or the provisions of Article 32, paragraph (1):
