In order to go through some of Japan's basic moves I'm going to have to make some assumptions since there are quite a lot of variations they can see due to the play out of R1 thru UK 1. So I'll assume any bid went to Germany, Russia attacked some combination of Wrus, Belo or Ukr, Germany took Egy, cleared out the Med of all Allied ships, and countered what it could in Europe, while the UK landed in Alg, countered Egy (or setup up an Afr counter in Rd 2).
