The website has been extensively revised.
We are planning to release new contents as soon as possible, so please wait for a while.

We currently recommend using Google Chrome to view this website. Due to some glitches in background processing, etc., if you view this website with a browser other than Google Chrome, there is a high possibility that the website will be difficult to view.
Because the administrator himself created this website, it is taking time for us to deal with the browser environment. Thank you for your understanding.
