Northeast Asia family wealth: Japan, Korea and Taiwan

What sets Northeast Asia family wealth apart from the rest of Asia?

Northeast Asia combines mature economies, strong manufacturing and families who still own or steer major companies. Wealth often sits inside the operating business, so a handover decision is also a decision about control, jobs and reputation. The family office has to serve the company as well as the household, and it has to speak the language of both the boardroom and the dinner table.

Each country adds its own habits. Japan values continuity of the house, Korea values group control through founding families and Taiwan values owner-managed firms that grew with exports. The sections below take each market in turn, then compare what they share and where Singapore or Hong Kong enters the picture. Read the section on your own market first.

How do long-lived family firms shape wealth in Japan?

Japan counts businesses that have operated for 100 years or more, called shinise. As of 2020 the country had more than 33,000 shinise, including 3,100 older than 200 years (Wikipedia, Shinise). Many are family firms, so succession has shaped Japanese wealth for centuries. That history gives Japanese families a long view of the handover, measured in generations instead of quarters.

The guide on Japan family wealth and succession explains how owners choose heirs, why some adopt a capable employee when there is no child to lead, and how a family separates ownership of the house from management of the firm. It suits founders and heirs who see the company as a duty to later generations, and who want a plan that protects the name of the house and the people who work there.

How do conglomerate families hold wealth in South Korea?

South Korea is known for the chaebol, a large conglomerate run and controlled by an individual or family. The chairman often holds a small share of the equity and keeps control through cross-holdings, a horizontal and vertical structure across affiliates (Wikipedia, Chaebol).

The guide on South Korea family wealth and succession looks at what this structure means for the next generation: who gains control, how siblings share it and how the family reports to the public. The pattern differs from a single company, because the family steers many affiliates through one holding chain. Public attention adds a second layer, since the handover of a large group becomes news.

How do owner-managed firms shape family wealth in Taiwan?

Taiwan’s economy rests on a dense base of small and medium enterprises, which provide 80% of employment as of 2025 (Wikipedia, Economy of Taiwan). Many are owner-managed firms in manufacturing and technology supply chains, built by a founder who still signs the major decisions.

The guide on Taiwan family wealth covers the planning that these owners face: choosing a successor, separating personal wealth from company assets and preparing the next generation. It also looks at how global supply chains and cross-strait links push owners to hold assets in several places, and how that spread raises questions of currency, residence and reporting.

What do Japan, Korea and Taiwan share in family wealth planning?

All three markets link wealth to a company, and all three face the same question: who leads when the founder steps back. Research on family firms stresses that succession depends on the size of the family relative to the business and on whether a successor has the skill and the commitment (Wikipedia, Family business).

A helpful tool is the three-circles model of family, ownership and management, which separates the roles that people hold. A relative can be an owner without being a manager. Drawing the circles for your own family clarifies who decides, who earns and who inherits. Planned succession leaves both the founder and the successor more satisfied, and power tends to shift gradually over several years.

Why do Northeast Asia families look at Singapore or Hong Kong?

Families from Tokyo, Seoul or Taipei often hold part of their investments abroad for diversification, access to funds and a base for the next generation. Singapore and Hong Kong offer banks, trustees and fund managers who work in English and serve clients across Asia.

A hub works as a complement to the home market, since the operating company usually stays at home. The family office can coordinate home advisers and hub advisers, collect reports in one place and keep a record of decisions. Each country keeps its own tax and legal rules, so local advice remains essential. A hub account can also hold the funds that the family keeps outside the company.

How can a Northeast Asian family start its planning?

Begin with 3 lists: assets by country, heirs by city and advisers by role. Add the company, with its owners and its managers. Then read the country guide that matches your home market and note the questions it raises for your family. Share the notes with your spouse and your eldest heirs before the first meeting with an adviser.
