At least six mosques and a Muslim organization in Japan have received threats since the hostage crisis that saw two Japanese men killed by the Islamic State militant group.

There are between 70 and 80 mosques in Japan, according to the Tokyo-based Japan Muslim Association. Among 16 mosques that responded to queries, six reported having received abusive telephone calls or emails.

Mosques in Sapporo, Tokyo, Yokohama, Nagoya, Ichinomiya, Aichi Prefecture, and Niihama, Ehime Prefecture, reported receiving abuse, as did the Japan Muslim Association.
