Showroom for agricultural machinery in Osaka

Hello,

We will be going to Osaka this April. Just want to know where in Osaka can we find agricultural machinery for sale/demo or a showroom for these things? My parents are interested in farming, particularly the Japanese way. Thank you =0

Osaka is big urban city area, no such large showroom.
Agricultural machinery exhibitions are irregular, but idk if it will be held in the next APR.

These big 4 companies are very famous, jump to EN pages. (fr EN or grobal)

While Japan is known for manufacturing big machinery. The Japan way is still more by hand for most farming.
