Sugai

Sugai is a Japanese surname and, less commonly, a geographic toponym. As a surname, Sugai can be written with several kanji combinations, each carrying its own meaning; the choice of characters reflects family lineage and regional history. The surname is modest in frequency and is most often found in Japan, with bearers living in urban and rural areas and in Japanese diaspora communities.

Sugai also appears in place names within Japan, where it may denote former holdings, local features, or geographic connections to a family or clan. In some districts, "Sugai" forms part of a longer locality name and may be encountered in historical or administrative records.

In contemporary usage, Sugai occurs in personal names, corporate or organizational names, and cultural references. The name is typically transliterated from Japanese using the Hepburn system as Sugai, but romanization variants may appear in non-Japanese contexts. The article could be expanded with specific kanji spellings, lists of notable individuals, and geographic entries, drawn from reliable sources. Until then, Sugai stands as a modest Japanese surname and toponym with multiple possible meanings determined by kanji and local history.
