You are very much wrong with your assumption that Germany helped Japan develop military technology. Japan was technological developed long before the 2nd WW and since 1870s.Germany helped Japan military with technology. Hitler even sent nuclear bomb materials to Japan.
Germany was just months late.
Imagine how the world looks like today.
Germany invented and fielded jet fighters and nuclear ballistic missiles in 1945.

And Emperor Kaiser came to the fore in 1880s when Germany started to develop its technological prowess. However, Germany had many technologies even before Kaiser.
Please read how the Japanese naval fleet defeated the then USSR naval fleet in 1905 in the Tsushima Strait. It was long before Hitler's Germany rose up.
It was the Japanese engineering people who developed, adopted, adapted and improved many technologies available in those days. No other country spoon fed Japan.
