Since September 11, 2001, safety concerns of Americans (and others) traveling abroad is a high priority. A visit to Osaka, Japan, though, is relatively safe, the country having had no major terrorist incidents since 1995.  American Citizens Services is a website that diseminates threat-related information.

That said, Japan has a very low crime rate compared to that of other countries. Most crimes against travelers consist of thefts, personal disputes, or vandalism. Narita Airport has received several reports in the past of passport theft and pickpocketing, so avoid carrying valuables in back pockets, if possible. Reports of crimes by visitors are not always fairly or sufficiently handled by Japanese authorities. In any crime, always request a copy off the police report.

Loss or theft of a passport while in Osaka should be reported immediately, as well as contacting the nearest embassy or consulate. It can take as long as three weeks to retrieve a new passport.

The streets of Osaka are narrow and without sidewalks, so space is shared by motorists, bicyclists, and pedestrians alike. Constant awareness is essential, and its common for newcomers as well as old hands to get lost. It is therefore very handy to know a little Japanese and/or have a Japanese-language dictionary.
