The YSD2 production was moved to Japan I believe after the change of ownership at some point. From what I understand the company is on it's third ownership since the original two brothers founded it (date?).
I've gone through two YSD2s and one YSD2J and have been using Black Eneloops and Eneloop Pros for several years. I rarely shoot at full power or multiple back to back shots as my usual subjects don't move that fast.
It would be good to have some independent study regarding use of certain batteries with certain strobes. I don't shoot with flash much topside, but when I do I use Eneloop Pros in my SB800 Nikon flash without any issues.
