第百五十八条（未成年者又は成年被後見人と時効の完成猶予）
If a minor or an adult ward has no legal representative during the period of six months preceding the expiration of the period of prescription, the prescription period does not expire with respect to that minor or adult ward until six months pass from the time when that minor or adult ward becomes a person with a capacity to act, or a legal representative assumes the position.
時効の期間の満了前六箇月以内の間に未成年者又は成年被後見人に法定代理人がないときは、その未成年者若しくは成年被後見人が行為能力者となった時又は法定代理人が就職した時から六箇月を経過するまでの間は、その未成年者又は成年被後見人に対して、時効は、完成しない。
If a minor or an adult ward has a right vis-a-vis the minor's or the adult ward's father, mother, or guardian who manages the property, the prescription period does not expire with respect to that right until six months have passed from the time when that minor or adult ward becomes a person with capacity to act, or a succeeding legal representative assumes the position.
