The Japanese had several Ju52s that were in civil service before the start of the war, I am sure they were appropiated by the military. I don't have any photos handy, but they should be easy to find, look for Eurasia Ju52/3M.
The He111 did see service in the far east, as the Chinese government purchased 6 He111A-0 types. Most were shot down by the Japanese during a raid near Shanghai. The Japanese were interested in licensing the He111 and an IJA designation was formed for it, the Type 98 but to the best of my knowledge, they never took delivery of any from Germany for evaluation.
Interesting that I don't see the Heinkel He112 on that chart, as the Japanese had purchased 12 He112B-0 types and used them during the Second-Sino war under the Army designation of A7He1. The Allies were aware of their presence and gave them the ID of "Jerry".
