Irokawa Space Center is in the southern part of the Nangan region in Forza Horizon 6. The easiest way to find it is to open the map, move to Nangan near the southern coast, and look for the large space center complex near Jodogahama Beach. It’s based on the real-world Tanegashima Space Center, Japan’s main spaceport.
The landmark is hard to miss once you are close because there is a huge rocket at the site. Drive toward the rocket at the southern tip of the Irokawa Space Center Drag Strip, then enter the space center area to the point of interest.
