This article explores why the average lifespan of a car in Japan is much shorter than in other countries. It looks at cultural reasons such as cars being viewed as status symbols, economic reasons such as taxes on second-hand vehicles, and government incentives for buying new cars. It also examines the Shaken system of vehicle inspections and how Japan's aging population affects car ownership. All these factors contribute to making it difficult for individuals who wish to keep their current vehicle longer but ultimately decide against doing so due either directly or indirectly because of these influences.
