Translation guide
In Japanese, 'change of era' refers to the transition from one imperial era name (gengō) to another. This is a culturally specific concept, and the most natural Japanese expressions depend on whether you are talking about the event itself, the act of changing, or the new era name.

Describing the process or decision to change the era name.
The English phrase 'change of era' can be ambiguous. In Japanese, you must specify whether you mean the event (改元), the name (元号), or the act (改元する). A literal translation like 「時代の変化」 (jidai no henka) means 'change of times/age' and is not used for the imperial era change.
Era names (gengō) are deeply tied to the emperor system. The change of era is a significant national event in Japan, often accompanied by public holidays and media coverage.
