Translation guide
In Japanese, the term for 'business partner' depends on the relationship and context. Common terms include 取引先 (torihikisaki) for a client/supplier you do business with, ビジネスパートナー (bijinesu pātonā) for a more equal collaborative partner, and 共同経営者 (kyōdō keieisha) for a co-owner. The choice reflects the nature of the partnership.
A company or individual with whom you have ongoing business transactions, such as a client, customer, or supplier.
