Ryujin 50



The Ryujin 50 or 50 Richest Okataians is a list published by East Asia Morning Post of the wealthiest 50 Okataian ranked by net worth. The list was criticized as it serves the interest of the Houshi, large corporate families such as Sundao or Oda. The title Ryujin stands for "Dragon men" as often, business tycoons are referred to as dragons in Oka.

The list has then been published each year in October since 2000, it originally appeared in the East Asia Morning Post special issue as a comparison between Oka and Teiko following the Onodera 40, it has since then been re conducted on a yearly basis. The Sundao Corporation founder and the current head of the Sundao Houshi, Akio Sundao has been Oka's richest man since 1995, Followed by Property Development Magnate Greg Shuzo since 2010. The richest woman is Maru Yoobei and is the only woman in the top 10. The Ryujin 100 tracks the 100 largest corporations in Oka
