Last month it was revealed that a Bangladeshi former associate professor at Kyoto's Ritsumeikan University was wanted by police for his suspected involvement in the Dhaka terrorist attack that killed 20 people in a cafe, including seven Japanese. Mohammad Saifullah Ozaki had been teaching business administration but disappeared from Japan sometime last year. He was finally fired in March.

Police in both countries are investigating whether Ozaki sent money to groups with suspected Islamic State links. While there is growing attention in Japan on physically preventing terrorist attacks, especially ahead of the Tokyo 2020 Olympics, this case shows how funding from Japan to suspected terrorists abroad is also a problem.

Japan has laws to halt terrorism funding, but are they sufficient?
