Chapter V Regulations on Machinery and Other Such Equipment, Dangerous Substances, and Harmful Substances (Articles 37 to 44-2)
The law as Act Partially Amending the Industrial Safety and Health Act and the Working Environment Measurement Act (Act No. 33 of 2025) leaves it, with the words it changes marked.
The main text is read a page at a time: a chapter to a page, and a long chapter in runs of articles. The whole main text, and the supplementary provisions and appended tables this amendment changes. Those it leaves untouched are on the page for the text in force.

Article 37, paragraph (1)
A person seeking to manufacture machinery or other such equipment that is set forth in Appended Table 1 as necessitating particularly dangerous work operations, and also specified by Cabinet Order (hereinafter referred to as "specified machinery or other such equipment"), must obtain permission from the Director of the Prefectural Labour Bureau in advance, pursuant to Order of the Ministry of Health, Labour and Welfare.
When a person has applied for the permission referred to in the preceding paragraph, the Director of the Prefectural Labour Bureau examines the application, and must not give the permission referred to in that paragraph unless the director finds that the construction of the specified machinery or other such equipment to which the application pertains complies with the standards provided for by the Minister of Health, Labour and Welfare.
An application for the permission referred to in paragraph (1) must be made, pursuant to Order of the Ministry of Health, Labour and Welfare, with a document attached that states the results of a review (hereinafter referred to as a "design review") conducted by a person registered by the Minister of Health, Labour and Welfare for each type of specified machinery or other such equipment pertaining to the machinery or other such equipment set forth in Appended Table 1 (hereinafter referred to as a "registered agency for design reviews and post-manufacturing inspections") as to whether the design of the specified machinery or other such equipment to which the application pertains conforms to the part of the standards referred to in the preceding paragraph that relates to the construction of specified machinery or other such equipment; provided, however, that this does not apply when the Director of the Prefectural Labour Bureau carries out the operations for design reviews of the specified machinery or other such equipment to which the application pertains pursuant to the provisions of paragraph (1) of Article 53-2.
Pursuant to Order of the Ministry of Health, Labour and Welfare, a person that has manufactured or imported specified machinery or other such equipment (limited to that pertaining to the machinery or other such equipment set forth in items (i), (ii), (iv) and (viii) of Appended Table 1; the same applies in this paragraph, the following paragraph and paragraph (1) of the following Article), a person seeking to install specified machinery or other such equipment which has not been installed for the period specified by Order of the Ministry of Health, Labour and Welfare, or a person seeking to reinstall or resume the use of specified machinery or other such equipment whose use has been discontinued must undergo an inspection by a registered agency for design reviews and post-manufacturing inspections with respect to that specified machinery or other such equipment itself and the related particulars that are prescribed by Order of the Ministry of Health, Labour and Welfare; provided, however, that this does not apply if, for specified machinery or other such equipment that has been imported and the particulars related to it that are specified by Order of the Ministry of Health, Labour and Welfare (referred to as "machinery or other such equipment subject to import inspection" in the following paragraph), the person that manufactured the specified machinery or other such equipment in a foreign country has undergone an inspection under the provisions of that paragraph.
Beyond as provided in the preceding paragraph, in a case set forth in one of the following items, pursuant to Order of the Ministry of Health, Labour and Welfare, a person that has manufactured specified machinery or other such equipment in a foreign country may itself undergo an inspection by a registered agency for design reviews and post-manufacturing inspections for machinery or other such equipment subject to import inspection:
if the person seeks to export the specified machinery or other such equipment to Japan;
当該特定機械等を本邦に輸出しようとするとき。
Article 38, paragraph (2), item (ii)
if the person that has imported the specified machinery or other such equipment is a person other than the person that has manufactured that specified machinery or other such equipment in a foreign country (in this item, such other persons are simply referred to as "other persons"), and the person that manufactured it does not wish to have inspections referred to in the preceding paragraph undertaken in respect of other persons.
A person that has installed specified machinery or other such equipment (excluding anything that is movable), a person that has changed any parts provided for by Order of the Ministry of Health, Labour and Welfare of specified machinery or other such equipment, or a person that seeks to resume the use of specified machinery or other such equipment whose use has been discontinued, must undergo an inspection by the Chief of the Labour Standard Inspection Offices in respect of the specified machinery or other such equipment and the related particulars that are prescribed by Order of the Ministry of Health, Labour and Welfare, pursuant to Order of the Ministry of Health, Labour and Welfare.
Pursuant to Order of the Ministry of Health, Labour and Welfare, a registered agency for design reviews and post-manufacturing inspections issues an inspection certificate for movable specified machinery or other such equipment that has passed an inspection as referred to in paragraph (1) or (2) of the preceding Article (hereinafter referred to as a "post-manufacturing inspection").
Pursuant to Order of the Ministry of Health, Labour and Welfare, the Chief of the Labour Standard Inspection Offices issues an inspection certificate for specified machinery or other such equipment that has passed the inspection referred to in paragraph (3) of the preceding Article in connection with the installation of specified machinery or other such equipment.
Pursuant to Order of the Ministry of Health, Labour and Welfare, the Chief of the Labour Standard Inspection Offices endorses the inspection certificate of specified machinery or other such equipment that has passed an inspection as referred to in paragraph (3) of the preceding Article in connection with the partial alteration or resumption of the use of specified machinery or other such equipment.
A person must not use specified machinery or other such equipment for which an inspection certificate provided for in paragraph (1) or (2) of the preceding Article (hereinafter referred to as an "inspection certificate") has not been issued (including specified machinery or other such equipment that must be inspected in connection with a partial alteration or resumption of use pursuant to the provisions of paragraph (3) of Article 38, but for which the inspection certificate has not been endorsed as provided for in paragraph (3) of the preceding Article).
Specified machinery or other such equipment for which an inspection certificate has been issued must neither be transferred nor leased out unless accompanied by that certificate.
