noun
spirit of dependence; reliance on others
Refers to a tendency to depend on others rather than acting independently. Often used in psychological or self-help contexts.
依頼心が強いと、自分で決断できなくなる。
If you have a strong spirit of dependence, you become unable to make decisions on your own.
彼は依頼心を捨てて、自立しようと努力している。
He is trying to become independent by shedding his reliance on others.
自立心 is the antonym, meaning a spirit of independence or self-reliance.
Compound of 依頼 (irai, 'request, reliance') and 心 (shin, 'heart, spirit'). The exact historical derivation is uncertain, but the word is conventionally associated with a dependent mindset.
