The 250000 yen is for the land only and does not include construction - the quote we got for a simple layout turned out to be 1000000 yen which was an amount that I could not invest in just for a show that lasts a few hours (from 11AM to 5PM). I decided to see if we could make a booth made entirely from only IKEA furniture + some of what we had in our office. We managed to bring costs down from 1000000 yen down to just over 100000 yen with a difference - we were still able to use the furniture after the event unlike many other companies who forked out millions of yen for a few hours and then have their booth torn down for good - most of them sold stuff though so they probably recuperated costs.
