Wong Yuen Store was built in 1914 by Chinese immigrant, Wong Yuen. The store currently the only store in operation in Waiohinu. Kauaha'ao Church was built in 1888 by Calvinist missionaries in Waiohinu. The historic church building was demolished in April 1998 because of extensive termite damage. Mark Twain visited Waiohinu in 1866 and, legend has it, planted a monkeypod tree. The tree was blown down in 1957, but a shoot from the tree was replanted and remains there today.
