Translation guide
The concept of licentiousness—lacking moral restraint, especially in sexual behavior—is expressed in Japanese through words that emphasize debauchery, self-indulgence, or moral corruption. The most common terms are 放蕩 (hōtō) for a dissolute lifestyle and 淫乱 (inran) for sexual promiscuity. Learners should note that direct translations can sound literary or harsh; context-appropriate expressions are key.
To describe a lifestyle or character marked by lack of moral restraint, especially regarding pleasure-seeking and self-indulgence.
Refers to a dissolute, debauched lifestyle; often used for someone who indulges in drinking, gambling, and women. Can be used as a noun or with する to mean 'lead a dissolute life'.
In his youth, he indulged in every kind of debauchery.
The prodigal son returned home.
Describes a self-indulgent, dissolute, or slovenly way of living; often implies laziness and lack of discipline. Less specifically sexual than 放蕩.

Means 'lustful' or 'lecherous'; often used for a person who is constantly seeking sexual pleasure. Slightly old-fashioned or literary.

The English word 'licentiousness' is quite formal and literary. In Japanese, directly translating it as 放蕩 or 淫乱 can sound overly dramatic or archaic in casual conversation. For everyday speech, use more specific terms like スケベ (lecherous) or describe the behavior with phrases like だらしない生活 (loose living).
放蕩 implies active indulgence in vices like drinking and womanizing, often with a sense of recklessness. 自堕落 is more about laziness and lack of self-discipline, leading to a slovenly lifestyle. 放蕩 is more about moral failing, while 自堕落 is about personal neglect.
You should refrain from lewd acts.
