We quite often fly captain/captain, especially if they're running low on FOs because of leave etc and the JCAB (Japanese CASA) have no problems with it at all. Until fairly recently there were no checks or training done and we just got on with it. However, an IOSA(?) audit suggested this was not a good idea and we now have to do an annual EFATO, 1 eng ILS and G/A followed by a 1 eng ILS to land, from the right seat. Normally if we're scheduled to fly capt/capt then the PIC is in the left seat and we normally just keep it as PF from the left seat as well. During the day/days together you'd both be in the left seat, so you're going to get to drive at some point but, occasionally, we'll mix it up and do a bit of PF from the right seat and try to remember how to pull and push with the other hand
