Is Japan Dangerous?

Also kawaii they do not all hate foreigners just certain areas have it a lot there are plenty foreigner friendly areas of Japan besides all of that the radiation I know isn't a problem the gangs can be but that all depends on your actions and your area. All in all the dangerous parts are all human related issues due to racial hate non surprisingly and the gangs but Japan has a pretty tight justice system so that does help

You are correct it is thanks ^^

Yep as long as you mind their mannerisms and stay in areas that are not as populated with the gangs there your good if you don't then you would see why it can be dangerous the gangs are not the ones in America they are more brutal and the honor system still plays very highly in there gangs depending on the ones but its all avoided as long as you stay in areas where they would not mess with you.

The yakuza won't mess with you as long as you don't interfere with or get entangled in their business. The yakuza actually have a code of conduct that its members live buy and they aren't likely to randomly mug you unless you give them a reason. This is the same Yakuza that provided truckloads and truckloads of emergency aid and supplies to the victims of the Great Tohaku Earthquake even faster than the government could. As long as you avoid shady areas and stay in well lit, populated areas, you'll be just fine.
