They founded a company instead of selling rights

🏢What the venture actually looks like#

The stakes and the roles the three firms split

Strip the press release language away and what remains is a cap table and a division of labor. Who holds the majority and who owns which function effectively decides what this company will end up making.

CJ ENM 51, TBS 40, U-NEXT 9#

The majority sits on the Korean side

The split is CJ ENM 51 percent, TBS Holdings 40 percent, U-NEXT Holdings 9 percent. A Korean company holds the majority while a Japanese terrestrial broadcaster and Japan's largest local streamer sit beside it as partners. In rights trading the seller was the weaker party; here the planning lead is placed the other way around.

Capital of 1.25 billion yen#

2.5 billion yen committed in total

Reported capital is 1.25 billion yen, with 2.5 billion yen committed across the three partners. Measured against the budget of a single drama that is not a large sum. It suggests this entity is less a place that shoots everything with its own money than a place that gathers planning and rights.

The roles split three ways#

Planning, Japanese IP, platform

CJ ENM leads planning and differentiation off its global production experience, TBS finds original IP inside Japan and drives IP business and channel scheduling, and U-NEXT acts as the primary platform for supplying and distributing originals. The one who makes it, the one who owns the source, and the one who airs it are all inside a single company.

The design is packed into the name#

'Mono' for story, 'wa' for harmony

Monowa joins 'mono', Japanese for story, with 'wa', meaning harmony. It reads as a space where Korean and Japanese content are connected into one, and the prefix also nods to CJ's ONLYONE philosophy. Naming a company this carefully signals an intent to build a brand rather than run a one-off project.

It started with one visit#

Tokyo, April 2025

The venture traces back to CJ Group Chairman Lee Jay-hyun's April 2025 trip to Japan. He met TBS Group Chairman Sasaki Takashi and CEO Abe Ryujiro to confirm the direction, and the talks moved step by step into a joint venture. A company standing within a year of that first meeting is unusually fast.

📈Why Japan, why now#

Market size and rate of growth

Japan was for a long time a market that its own content served well enough. But the pace at which that market is growing and the pace at which it is shifting to streaming have overlapped, opening a gap that outside planning can enter.

A market of roughly 67 trillion won#

25.6 trillion of it original IP

In the Roland Berger figures CJ ENM cited, Japan's content IP market was worth roughly 67 trillion won as of 2023, with about 25.6 trillion of that in original IP. The number spans IP development, video production, streaming and spin-off business. Set against Korea's entire content industry, the difference in scale is immediate.

Streaming growing 20.5 percent a year#

The ground is moving

The same source puts Japanese streaming growth at 20.5 percent a year. In a market where terrestrial television is strong, that pace means viewing habits really are shifting, which is why a terrestrial broadcaster and a streamer ending up in the same company is no accident.

It has worked before#

The Japanese Marry My Husband

Last year CJ ENM produced the Japanese remake of Marry My Husband as an Amazon Original, and it topped the drama category of Google Japan's Year in Search 2025. It is the case that showed, in numbers, that Korean planning still lands after passing through Japanese casting and a Japanese production environment.

They had already made one together#

A Studio Dragon co-production with TBS

Studio Dragon, part of the CJ ENM group, has jointly planned and produced a Korea-Japan drama with TBS. The joint venture is that relationship hardening from the project level to the corporate level. Founding a company with a partner you have already worked with carries a different order of risk than founding one with a stranger.

🔍What is still unconfirmed#

Where to look if you do not want to be sold a number

A launch announcement is a plan, not a result. Three things actually need checking before judging this venture, and as of August 2026 not one of them has been made public.

There is no first lineup yet#

A title is the evidence

As of August 2026 StudioMonowa has announced no individual titles. The same goes for production start, casting and scheduling. A venture like this is judged not by its press release but by where its first title lands and how long it stays there.

Co-production or remake#

The credits decide, not the wording

The announcement says development is joint from the earliest planning stage, but where the planning actually came from ends up in the finished credits. Reshooting a Korean original in Japan and writing something in both countries from the start leave different IP ownership behind.

How far the U-NEXT exclusivity runs#

A narrow window narrows the numbers

U-NEXT being the primary platform means the first window inside Japan is settled. How long that exclusivity lasts, and how distribution opens in other countries, has not been disclosed. A narrow window can produce plenty of buzz and still recoup slowly.

🎬What changes on the location side#

Co-production multiplies places

As co-productions increase, a single title gets shot in two countries and the number of places you can actually visit grows with it. That is especially true of films where place is the ground of the story, like Jung Ji-young's My Name Is, set against the Jeju 4.3 events.

🛠️Localization becomes standing work#

A pipeline, not a translation job

When you sell finished titles, localization is something bolted on once after the sale. When planning is shared, two languages run from the script stage and subtitling, dubbing and rights administration turn into standing work. That is where per-delivery pricing becomes possible.

🧭A job opens up#

From producer to global producer

For producers and planners who only ever watched domestic scheduling, Korea-Japan co-production sets new requirements: reading both countries' production habits and scheduling grammar at once, understanding contracts and rights windows, and running meetings in two languages. That few people yet meet those conditions is exactly what makes the position valuable right now.

📊What an investor should watch#

The schedule, not the announcement

The founding of a joint venture is the kind of news a share price reacts to for a day or two and then forgets. What actually needs checking is when and where the first title airs, how far it sells outside Japan, and whose books the revenue lands on. With a 51-40-9 split, it will not land equally.
