It's Japanese, twin engine, single pilot. Could it be the Ki-45?
It doesn't quite match the photos I've been able to find (pressure gauges on the other side of the panel for one thing)
But it could be a different variant...
p.s. apologies for not being around to comment on the last pic I submitted - I was away on a course over the weekend and by the time I managed to check in, you'd (correctly) ID'ed it and moved on!
