Itoh

Itoh is a romanization of the Japanese surname Itō, commonly found in English-language contexts. It can be spelled in several ways in the Latin alphabet, including Itō, Ito, Itou, and Itoh.

The surname is most commonly written in kanji as 伊藤 or 伊東. The first character 伊 is a frequent phonetic element in names; the second character in 伊藤 is 藤, often associated with wisteria, while 伊東 uses 東, meaning “east.” The two forms are distinct family names, though both are read as Itō in Japanese.

In everyday use, Itō is the standard reading, with the macron over the o used in formal romanization to indicate a long vowel. Variants such as Ito, Itou, and Itoh arise from different romanization schemes or personal choice when adapting the name for non-Japanese contexts.

Itoh is one of the more common Japanese surnames and is borne by many individuals in Japan and among Japanese communities abroad. Like many surnames, its precise regional distribution and historical origins can be linked to family lineages and place names rather than a single source.
