Translation guide

In Japanese, there is no single direct equivalent; the best translation depends on whether you mean economic cycles, natural cycles, repetitive patterns, or circular reasoning.
Describing events, trends, or phenomena that repeat in a predictable cycle, such as economic booms and busts, seasons, or life cycles.
