I wanted to find out more information about travelling to Japan and check and see how individuals handled various situations like buying tickets, traveling in trains, handling the language barrier, visiting the shrines, and eating out. So I found out that http://www.japan-guide.com/ is one place to start.
One can simply go to this website and click the "Forum" tab and browse through vaious questions and answers posted by newbies and experienced folks. But if you wanted to post a question, like other forums, you have to register (for-free).
When you search certain terms one gets both forum answers and relevant advertisements for that item. Like if you search for "stay" you get results that give information about where to stay in various cities as well as advertisements for hotels. Similarly if search for "food" you get information about Japanese food, food habits, and resturaunts. I found this site very useful.
