Top 11 Ultra-Rich Families in Japan and Their Net Worth

Wealthiest Business Families in Japan

Overview: Wealthy Households in Japan

In Japan, there are 1.49 million affluent households with a combined net worth of 364 trillion yen, as per the Nomura Research Institute.

It is anticipated that financial institutions will provide assistance to future business owners who are eligible for the wealthy class, as wealthy households and total net financial assets continue to increase.

The number of high-net-worth and ultra-high-net-worth households increased from 1.327 million in 2019 to 158,000 in 2021, marking the highest number since the inception of this estimation in 2005. The number of households in both the wealthy and ultra-rich has steadily increased since 2013, when the Abe administration's economic policy, or "Abenomics," was implemented.

According to a survey conducted by the National Research Institute (NRI), approximately one-third of individuals with financial assets ranging from 100 million to 500 million yen in Japan operate their own businesses. A critical market for financial institutions is the recent emergence of startup managers as business owners. In order to aid startups in the establishment and operation of their businesses, financial institutions must understand and comprehend the concerns and obstacles they encounter.
