I got the same Problem as JRakan but the solution didn`t work for me.
I hit the cancel button and the game closes.
Sys. is japanese and even changing the Locale to Jap. won`t help.
For those wit the problem of the Japanese locale, i found a solution, hope it can help you.
First of all, if you downloaded this one, in the folder that contains the iso of the game there's a rar file named repair, and inside it there's a txt named Seen, copy the Seen.txt in the folder where the game is installed and replace the file SEEN.txt with Seen.txt, after that use this View attachment jyoisan_patch.rar. This should make the game run without problems.
