I think that they had decided on that question several years earlier, that it was in their best interest to stick to a doctrine to pacify Russia and concentrate on Asia.

For sure an attack on Russia would have played into Hitlers hands, but I am not sure that the Japanese Army would have been able to make any impact on Russia as the Navy could against the US. Just look at Russian and Japanese tanks of the era to see what I mean.
