Successive wartime destroyer classes increased Japan's capabilities as its fleet grew. Japanese crews could compare their own first- and second-class destroyers with British ships and learn which features remained useful or became frustrating in routine service. Living with a car for six months provides the analogy: daily use reveals different things from watching someone else drive or riding as a passenger. Features that first seem like harmless quirks can become persistent annoyances, exposing practical strengths and faults that distant observation misses.
