Well this site is probably accessable to every country, but theres no way a japanese would read from this site lmao theyre the source, they have tons of manga store and tons of manga raw sites. Why would they even bother to search for some english site
i think this site is mainly english so no, but they probably have other sites similar to this :)
they usually go out to buy manga as its super cheap in japan, otherwise they probably have their own sites as this is mainly English
Is mangago available in japan?
