Every year, a group of elderly people march to the Consulate-General of Japan in Hong Kong to demand compensation for military yen. They have been doing this since the end of the second world war, but nothing has been resolved.
But what is military yen and why should we care about this issue?
BACKGROUND
Introduction of military yen in Hong Kong
After Hong Kong's surrender to Japan on December 25, 1941, Japanese authorities decreed the military yen would replace Hong Kong dollars as the official currency in the territory.
The exchange rate was fixed at HK$2 to one military yen in January 1942 and people were forced to change Hong Kong currency for Japanese money. Later, the military yen was re-valued at HK$4 to a yen in July, 1942.
In June, 1943, military yen was made the sole legal tender in Hong Kong. Anyone found to be using Hong Kong dollars or other foreign currency were severely punished or even executed.
