Japan's first post-WWII arms exhibition

For the first time since World War Two an arms exhibition has opened its doors in Japan.

Last year the Japanese government lifted a self-imposed ban on the export of weapons, and now Japanese arms manufacturers are showing them off to international buyers at home for the first time.

Japan has a large and advanced arms industry, but up to now it has only had one customer.

Rupert Wingfield-Hayes went down to Yokohama to take a look.
