I am a native Japanese speaker who lives in the USA.
I grew up in Japan, so I am very familiar with Japanese culture.
I used to work at a trading(exporting/importing) company, translating business documents, emails, and market info.
I am highly detailed and eager to complete tasks by their deadline.
My wife is a highly educated, American software developer. Though she speaks Japanese, we only speak English at home, and so I am familiar with both formal and informal English.
