This article explores the pros and cons of using cash or credit cards in Japan, as well as alternative payment methods such as prepaid debit cards, mobile wallets, and digital currencies. Cash is widely accepted throughout the country but offers no additional protection against fraud or identity theft like a credit card does. Credit cards offer more convenience than cash and usually come with rewards programs, but they also come with fees such as annual membership fees or foreign transaction fees which can add up over time if used frequently enough. Safety considerations for both cash and credit cards include keeping wallets close at all times and keeping copies of passport/credit card information stored separately from where actual documents are kept.
