Here is a Gallery of romusha-related photos; most taken by Australian Teams at the time of liberation. But some are from IJA archives
A DEATH RAILWAY CENOTAPH AT THE IPOH RAILWAY STATION
The importance of original documents is very well shown in that this photo is published on the internet in various places as Thai TBR workers at NongPlaDuk. Yet, when one looks at the Japanese language inscribed on it it says Burmese TBR workers with no reference to the exact place. There would have been no Burmese romusha anywhere near NongPlaDuk.
