Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
I've converted some Japanese infantry from WW1 British Airfix. The Russians - simply HAT WW1 or other WW2 figures with a head conversion.
On the other hand, there are a lot of metal figures for this war on the market now. I've found a new one which produced 15 sets of Japanese alone in the last few weeks. I've got the figures last week, they are great! More will follow.
Andrew Hughes has some simple paint jobs to produce what look awesome Russian and Japanese formations.

The Strelets Boer War range offers Indian and British formations for the Boxer Rebellion. And the WW1 and Crimean War sets also offer heaps of figures.
