Looks like eroge maker Minori has blocked access from outside of Japan who will see the following message:-
minori official website.
This website cannot be browsed excluding Japan.
Some foreigners seem to be having an antipathy against EROGE.
Therefore, We prohibited the access from foreign countries, to defend our culture.
Sorry for you of the fan that lives in a foreign country.
As for the first photo - submitted by De-JaY - a loyal EF fan who will probably be disappointed about the news.
Speaking about EF - check out the OP with the breathtaking backdrops from Makoto Shinkai.
This is rather sad. Especially since minori's newest project, called "eden*" will also be released in an all-ages version. :(
