Apple's recent decision to raise the prices of its iPhone models in Japan is leading to a notable increase in demand for used iPhones. This trend is happening amid concerns over the high costs of new models, and customers are now looking for economical alternatives. The increased prices were announced last week and since then, second-hand retailers have been witnessing a sudden surge in sales.

In Japan, buying high-quality second-hand items is highly respected and considered sustainable, contributing significantly to the disposal issue. The price increase of iPhones perfectly underscored the widely-accepted market for used but well-maintained good in the country. Consumers value affordability, durability, and the aspects of responsible consumption in considering their purchases.

In contrast, in the US or EU, although second-hand sales are popular, they may not experience the same dramatic increase in response to price hikes, as there's a stronger culture of getting the newest hardware immediately on release. The option to buy phones through carriers with subsidies or on installment also affects the situation differently than in Japan, where full payment upfront is more common.
