The Chinese (KMT and CP) fought long and hard, but the Pacific War was a maritime war; the IJA conquered everything it realistically could have held and exploited with about 12 infantry divisions.
Of which the IJN and the JMM never moved more than about four at a time...
Conquering France in 1940 required an Axis OOB second only to what they concentrated on the Eastern Front in 1941-42; there were more German divisions in the OOB to conquer France in 1940 then there were to defend against the allies in France in 1944...
As far as deployable combat forces, counting divisions is shorthand, but still - by 1944-45:
France: 1st, 2nd, 5th armored; 1st (Motorized), 1st, 2nd, 3rd, 4th, 9th, 10th, 14th, 27th infantry (12 divisions, of which 8 were in action in 1944);
Canada: 1st, 2nd, 3rd, 4th (Armoured), 5th (Armoured);
Poland: 1st Armoured, 2nd Armoured, 3rd Infantry, 5th Infantry;
As a point of comparison, China managed to deploy three divisions - 22nd, 30th, 38th - outside of their "home" theater, as part of the X Force/NCAC in Burma.
The Indian Army OOB (which, of course, was about 20-25 percent "British") include the following that served "away" from India:
1st/31st Armoured; 4th, 5th, 6th, 7th, 8th, 10th, 17th, 19th, 20th, 23rd, 25th, 26th Infantry ( 13 total; in addition, the 9th, 11th, and 14th divisions were lost "overseas", essentially, in 1942)
Including air and naval units bumps Canada up (the RCN was the third largest navy in the world in 1945), but the French air and naval strength was substantial as well.
