About pop-up blocker

Depending on your browser or additional applications added to your browser, pop-ups on this site may be blocked and may not be displayed.

There are a wide variety of applications and environments that have pop-up blocking functions, so we will only introduce some of the most common ones, but we will introduce pages that show countermeasures. Please note that the function may be enabled for multiple applications at the same time. (For example, if the pop-up blocking function for the Google Toolbar is enabled at the same time, addressing only one of them may not solve the problem.)
