Osaka can be relatively affordable compared to other major cities in Japan, such as Tokyo or Kyoto. However, travel, accommodation, and food costs can still add up, especially if you plan to visit famous attractions and eat at high-end restaurants. The cost of travel also depends on the season, with peak travel times being more expensive. However, many budget-friendly options, such as affordable guesthouses, street food, and free attractions, can make Osaka a cheap destination.
