noun
Orientalist; expert on the East
Refers to a person well-versed in Eastern (especially East Asian) cultures, history, or affairs. The term can sound somewhat dated or academic; in modern contexts, more specific terms like 東洋学者 or 東洋文化研究者 may be preferred.
彼は東洋通として知られ、中国や日本の歴史に詳しい。
He is known as an Orientalist and is knowledgeable about Chinese and Japanese history.
Compound of 東洋 (Tōyō, 'the East; Orient') and 通 (tsū, 'expert; connoisseur'). The suffix 通 is commonly attached to nouns to indicate a person with deep knowledge or familiarity.
