Genealogical research on the last name Tsunekawa

The Tsunekawa surname is predominantly Japanese, originating from the island of Honshu. It is a patronymic name derived from the given name Tsuyoshi, which means "strong" or "brave." The Tsunekawa family can be traced back to the Edo period (1603-1868), where they resided in the Kanto region. During this time, the Tsunekawas were samurai serving under the Tokugawa shogunate. After the Meiji Restoration in 1868, the feudal system was abolished, and many samurai families, including the Tsunekawas, lost their status.

The Tsunekawas later immigrated to the United States, primarily to Hawaii and California, during the late 19th and early 20th centuries, seeking new opportunities following Japan's industrialization and westernization. Today, there are significant Tsunekawa communities in Hawaii, particularly on Oahu, where many work in agriculture, healthcare, and education.

Researching your family history with the surname Tsunekawa can involve studying Japanese genealogical records, immigration records from Japan and the United States, as well as census data and local histories from Hawaii and California.
