Osaka is a great destination for senior travelers. The city has a great mix of modern life and traditional Japanese culture without the big-city crowding of Tokyo.

The subway and train systems are excellent and cover just about the entire city area. The subway offers a one-day pass for $12, and has a great website in English offering detailed schedules and maps.

The Osaka Aqua-Liner tourist boat sails the Okawa River. Among the many historic sights along the route is Osaka Castle, an ancient fortress, featuring a museum with fascinating examples of Japan's feudal past.

While Tokyo may have more fancy Western-style restaurants, Osaka has more authentic Japanese cuisine, along with Asian-influenced flavors. The classic Dotonbori restaurant district offers a great variety of traditional Japanese food choices.
