Japan, for one. At the end of WWII, the US Army of Occupation took away all the guns. The Government of Japan never removed restrictions on gun ownership.

In 2013, 12 people in Japan were killed by guns.

The laws keeping "civilians" from owning effective personal weapons go back to a minimum of 1588: https://en.wikipedia.org/wiki/Sword_hunt

I don't think there's any removing of Japanese crime and crime control from the following 2.5 century Tokugawa military dictatorship, which had profound effects in creating modern Japanese society.

Japan's not the best example to hold up as a success for gun control. The last 70 years have been nice.

During the prior 400 years, the various Japanese governments used gun and sword confiscation to enable crimes ranging from brutal to genocidal.

They don't have the demand. As I said, taking away guns from people who want guns will just cause them to build their own guns.
