A blue ocean is a market where customers have a real need and nobody is serving it well, usually because the work looks unprofitable, awkward or beneath the notice of established firms. Finding one is less about inventing a new category than asking why people struggle to get something done and whether you can remove that difficulty at a price they will pay. The idea is only useful once it survives contact with paying customers and a delivery model that works.

What is blue ocean strategy?

The term comes from W. Chan Kim and Renée Mauborgne’s 2005 book Blue Ocean Strategy. A red ocean is a market where competitors fight over the same customers with the same offer, so margins fall. A blue ocean is market space that competitors are not contesting, often because they have not seen it or have decided it is not worth serving.

Their best-known example is Cirque du Soleil. The traditional circus was losing audiences and relied on expensive star performers and animal acts. Cirque dropped the animals, kept the tent and acrobatics, added theater and music, and sold tickets to adults at theater prices. It did not win by being a better circus. It changed what the customer was buying.

The useful lesson for a small business is narrower than the marketing around the book. You rarely need an uncontested category. You need a group of customers who are poorly served by what exists, and a way to serve them that your competitors cannot or will not copy quickly.

Why do neglected markets stay neglected?

In Japan the reasons are often structural rather than a lack of demand.

  • Small ticket sizes. A rural house selling for a few million yen earns a real estate agent a small commission for the same paperwork as a city apartment, so many agents do not bother.
  • Scattered information. When the data a customer needs is spread across municipal sites, paper notices and people’s memories, nobody can serve the market efficiently until someone organizes it.
  • Language and distance. Customers overseas who want something from Japan often cannot find it, pay for it or have it explained in a language they read. Since 2025, US import duties have added another layer of friction for sellers shipping from Japan.
  • Established channels. Industries with layers of wholesalers and long relationships leave little room for a direct offer, until one of those layers disappears.

Each of these looks like a reason to stay away. Each is also the reason the space is open.

What does this look like in real projects?

Two areas I have worked in show the pattern.

I co-founded Akiya & Inaka, a venture built around Japan’s rural vacant houses. The conventional view treats most akiya as liabilities. The practical obstacle is that information about them is fragmented across local listings, municipal records and inconsistent documentation. My part included scraping, cleaning and structuring property data, and going out for searches, inspections and coordination with local providers. The opportunity came from doing the unglamorous work of making scattered information usable, which I describe in why akiya information is broken.

Through Kaala and Music in Japan, I produced events and built publishing, archives and discovery tools for independent music. Live shows in Japan are announced across flyers, social accounts and venue calendars that are hard to search, especially for people who do not read Japanese. The gap was never a lack of good music. It was that audiences and artists could not find each other easily, which is the problem behind Music in Japan.

Neither project needed a new technology. Both needed someone willing to take on work others avoided because it was slow and fiddly.

How do you find a blue ocean opportunity?

Start with a complaint, not an idea

Listen for where customers work around a problem: spreadsheets passed between people, phone calls to fill a gap, trips they make only because nothing online works. Repeated complaints about the same friction are better evidence than enthusiasm for your idea.

Ask what the current options force people to accept

Every market has compromises customers have stopped questioning, such as waiting a week for a quote, paying for features they do not use or dealing only in Japanese. Removing one important compromise is often enough to create a distinct offer.

Look at what incumbents ignore on purpose

If the established players avoid a segment because it is too small, too rural or too much trouble, ask whether a leaner operation could serve it profitably. Their cost structure is not yours.

Check whether the gap is real or just empty

Some markets are empty because nobody will pay. Before you build anything, find evidence that a reachable group spends money or time on the problem today.

Turn the strategy into an operating test

A blue ocean argument is a hypothesis until customers change their behavior. Define the customer who is poorly served, the job they are trying to finish and the compromise they currently accept. Then build the smallest offer that removes one important compromise without importing the incumbent’s whole cost structure.

Run interviews around a real decision, not general interest. Ask what the customer used last time, what triggered the purchase, who objected and what happened after the choice. Compliments about an idea are weak evidence. A deposit, a signed pilot or access to the customer’s working process is stronger.

The operating model matters as much as the positioning. A novel offer can fail because support, fulfillment or acquisition costs make every sale unprofitable. Track delivery time, repeat demand, margin and how often the founder has to step in personally. If the offer only works while one person performs heroics, the market may be attractive but the system behind it is not ready.

What goes wrong?

The most common failure is paying to educate a market that a later competitor then serves more cheaply. If nobody knows the category exists, budget for explaining it, and build something that is hard to copy, such as data you have collected, relationships with local partners or a process refined over many deliveries.

The second is mistaking novelty for need. A clever offer that solves a problem customers do not feel strongly will not sell, however uncontested it is.

The third is growing the offer before the delivery is repeatable. Scattered information, manual coordination and one-off workarounds are fine in a pilot. They become the business’s main cost once demand grows.

Where to start

Pick one customer group you already understand, write down the compromise they accept today and test a single change with a handful of real buyers. If the test works, the next problem is operational: bookings, payments, data and the tools that let the offer run without constant intervention. My Diagnostics engagement is a practical way to see which of those pieces are missing before you scale.
