I started this page to combine some of the info scattered over the internet. Use the categories on the right to browse the different sections of this blog/site.
It has a special section about concert tickets which is based upon a popular topic started by immel on the Ayumi Hamasaki Sekai forum (also known as AHS), which discussed everything from where to get tickets, where to stay cheap and other helpful information for visiting Japan. Since it's getting more 20 pages long it's a lot to digest.
