Dear Art san,
Thank you very much for sending detail information which shows your ideas for cost reduction.
I have already informed your ideas to HAC-ID R&D based on preliminary information sent by Sugiyama san. HAC-ID will discuss with our supplier (Kumar Auto) if those ideas can work for them.
HAC-ID R&D Team,
As I have informed you yesterday, please discuss cost reduction with Kumar Auto.
Kind regards.
AY
