Can anyone say whether this is also the case for the "Japan" version?

Do I need to get an older one (F-Zuiko) in order to have the lens design similar to the 1.4 and Pentax M 1.7 50 which I am used to, as shown in the front page of the same UCL site, where the front group doesnt have the doublet?

Why are you worried about the design of the lenses? Most all fast normals for 35mm are a variation on the Double Gauss formula, with various tweekings to add the requisite degree of retrofocus. They all, once you get above a certain level of performance, behave similarly.
