Hello,
I am interested to work on your project.
Though I am not a native Japanese speaker, I am living here for more than 6 years & working in a Japanese company as an engineer, and hence can assure you a native level of Japanese. I have to communicate in Japanese on phone as well as through email with clients, branch offices etc. I hope this will demonstrate my communication ability in Japanese.
With above given descreption, I can assure you that I will be best cadidate for your project.
Hoping to hear from you soon,
Regards,
