**第一項**  独占的状態があるときは、公正取引委員会は、第八章第二節に規定する手続に従い、事業者に対し、事業の一部の譲渡その他当該商品又は役務について競争を回復させるために必要な措置を命ずることができる。ただし、当該措置により、当該事業者につき、その供給する商品若しくは役務の供給に要する費用の著しい上昇をもたらす程度に事業の規模が縮小し、経理が不健全になり、又は国際競争力の維持が困難になると認められる場合及び当該商品又は役務について競争を回復するに足りると認められる他の措置が講ぜられる場合は、この限りでない。
<sup>art-8-4/par-1 · https://japanlaw.org/en/antimonopoly-act/art-8-4/par-1</sup>
When a monopolistic situation exists, the Japan Fair Trade Commission may order the relevant enterprise, pursuant to the procedures as provided in Section 2 of Chapter VIII, to transfer a part of its business or to take any other measures necessary to restore competition with respect to the relevant goods or services provided, however, that this does not apply if it is found that the measures may reduce the scale of business in relation to the relevant enterprise to such an extent that the expenses required for the supply of goods or services that the enterprise supplies will rise sharply, undermine its financial position, or make it difficult to maintain its international competitiveness, or if alternative measures that are found to be sufficient for restoring competition with respect to the relevant goods or services can be taken.
