Best Answer

1. The Wall Street Crash. It crippled the USA's economy and therefore they starting importing less. Japan also struggled without enough trade from the USA. Eg; One of Japan's key exports was silk and America decided to stop importing it, making it themselves instead.

2. To try and gain more Natural Resources and raw materials to support their massive expansion and militarization. They no longer wanted to rely heavily on the U.S for resources and decided Manchuria was ideal for a Japanese expansion since it was already fighting a civil war between nationalists, communists and warlords.
