Well, while I was living there, I always traveled alone on my longer trips (9 days through western Japan, 8 days through eastern Japan). On shorter 1 day trips (Nara, Kyoto, Koyasan, Nachi, etc) I often went with other people, except on my manga-hunting trips to the back alley shops in Osaka.

If I were to go back to Japan again, I'd really like to go with someone. None of my friends or family could afford to visit me while I was living there, so I'd like to show them around the country, let them see and experience at least a taste of where I lived.

Did you have some more specific questions about traveling alone? I enjoyed it, it allowed me to keep my own schedule, go where I wanted when I wanted, etc. And Japan is very safe, so I never worried about my safety.
