Markovich, the aviation authority which provided the licence you are submitting to Skymark for conversion to a Japanese one should give you a "no incident/accident report" for a small fee. Your contract agency should guide you in the right direction if you ask them.
There is a reason so many foreign (gaijin) Captains have left recently and continue to leave. Skymark used to be a good little company to work for, but times have changed.
