Pau Hana Lounge was a tiki bar, part of On the Hiyu, a rental facility from Seattle, Washington, based on a previously retired ferry. The 165-foot ferry, called the Hiyu, was converted into an arts space, which was available for special event rental, and which hosted some public arts events including music and cabaret acts. The ferry had two interior passenger compartments, and one contained the Pau Hana Lounge which was created by Aleks Petrovitch, a longtime member of the tiki revival scene who used to own Aqua Surf Shop in San Francisco, and Tiki Bosko of San Diego. The work started in summer 2017, and the bar opened in late 2017 or early 2018. The Hiyu was moored on the east side of Lake Union.
In May 2022, after having been temporarily closed for a time, On The Hiyu posted in social media that they moved to Cabo. As of December 2022, their boat is still posted for sale.
