How to do a Korea market feasibility study — and what to do with the results

A feasibility study is one of the most useful things a company can commission before committing to Korea — and one of the most commonly mishandled. Done badly, it produces a document that confirms what everyone already believed and collects dust. Done well, it gives a leadership team or investment committee the information they actually need to make a decision.

This article sets out what a Korea market feasibility study should contain, how to structure the research process, and how to use the output to make a sound decision about whether and how to enter.

When you need a feasibility study

The trigger is usually one of three things: a specific market opportunity has appeared (a potential partner, a regulatory change, a competitor move), leadership has decided Korea should be evaluated as part of a regional expansion plan, or a previous Korea attempt did not go as expected and the company wants to understand why before trying again.

In all three cases, the study serves the same purpose: replacing assumption with evidence, and giving decision-makers a clear picture of the risk-adjusted opportunity.

What a feasibility study should cover

Market sizing and structure. How large is the addressable market for your specific product or service in Korea? Not the total Korean economy, not the total relevant sector — your specific addressable market, defined by geography, customer type, price point, and competitive positioning. This number is rarely found in a single report. It requires triangulation across multiple sources and some modelling.

Competitive landscape. Who is already operating in this space in Korea? This includes both local Korean competitors (often underestimated by international companies) and other international players who have entered. What market share do they hold? What are their strengths and weaknesses? Where are the gaps that an international entrant could exploit?

Customer research. Do Korean consumers or businesses want what you are offering? At what price point? Through what channels? With what adaptations? This requires primary research — surveys, interviews, or observational work — not assumptions based on performance in other markets.

Regulatory and compliance landscape. Korea has specific regulatory requirements across most sectors, from food and cosmetics to financial services and healthcare. A feasibility study should map the relevant regulatory environment and flag anything that could affect entry timing, cost, or viability.

Entry options and scenarios. There is rarely only one way to enter a market. The study should model at least two or three distinct entry approaches — direct entry, partnership, licensing, distributor model — with realistic cost and timeline estimates for each, and a view on the trade-offs between them.

Financial modelling. What does entry actually cost? What is the realistic revenue trajectory under conservative, base, and optimistic assumptions? At what point does the investment break even? These numbers need to be grounded in actual Korean market data, not extrapolations from other markets.

Common mistakes

The most common error is commissioning research that is too broad. A report on "the Korean consumer goods market" is not a feasibility study for your specific product. Specificity is what makes the output useful.

The second most common error is relying entirely on desk research. Secondary data gives you context. It does not give you the customer insight, the competitive intelligence, or the regulatory nuance that comes from primary research and conversations with people who know the market.

The third error is treating the study as a final answer rather than a starting point. A feasibility study tells you whether to proceed and how. It does not substitute for the ongoing learning that comes from actually operating in the market.

Using the output

A well-structured feasibility study should end with a recommendation — not a list of considerations, but a direct view on whether the opportunity is real, which entry approach makes most sense, and what the key risks are. It should be written for a decision-maker who will read it once and needs to be able to act on it.

If the recommendation is to proceed, the study transitions into a market entry plan. If the recommendation is to wait or not proceed, the study should explain why — and what would need to change for the opportunity to become viable.
