The R2UK also has hardsubs. One advantage is it has the 1h7m Making Of with subtitles, the R2J has no subs for this and it's only available on the second disc of the more expensive premium release.
Note: the english subs on this disc are fine in the beginning, but gradually fall out of sync. At the end of the film the subs lag approx 0.4 seconds. The R2J does not suffer from this.
