Useful Tips
If you have more time, consider taking a day trip to Hiroshima or Kobe. If you have less time, consider skipping some of the activities and spending more time in Tokyo, Osaka, or Kyoto. Don't forget to try local specialties like sushi, okonomiyaki, and takoyaki. Bring comfortable walking shoes, as many of the sites require walking. Consider getting a Japan Rail Pass for long-distance travel between cities.
