Japan and South Korea Forge a New Era of TV Drama Co-Productions

The cultural exchange between Japan and South Korea has long been a one-way street, with K-dramas like Crash Landing on You and Itaewon Class captivating Japanese audiences during the pandemic. But the tide is turning. A new wave of cross-border TV dramas is emerging, blending talent, production techniques, and storytelling sensibilities from both sides of the Korea Strait. At the forefront is Eye Love You, a romantic drama that cleverly uses language as both a plot device and a marketing hook, proving that audiences are hungry for hybrid content that defies traditional boundaries.

Breaking the Language Barrier: 'Eye Love You' Finds a Formula

Produced by Tokyo Broadcasting System Television Inc. (TBS) and aired from January to March 2024, Eye Love You stars Japanese actress Fumi Nikaido as a woman cursed with the ability to read minds—until she meets a South Korean international student played by Chae Jong-hyeop. The twist? She cannot understand his thoughts because they are in Korean, a creative choice that resonated deeply with bilingual and monocultural viewers alike.

The drama became a rare Japanese series to crack Netflix’s top viewed list in South Korea for two consecutive months. Producer Keisuke Nakajima admits he was “surprised but satisfied” by the reception. For Nakajima, the project was born out of the pandemic-era K-drama boom. “I saw how much Japanese viewers loved Korean shows, and I wondered if we could create something that returned the favor,” he recalls.

The series also sparked a grassroots fan movement, with Japanese and Korean viewers creating online communities to share reactions and translations. It proved that the language barrier, often seen as a hurdle, could become a unique selling point.

Behind the Scenes: The High Cost of Collaboration

While the final product charmed audiences, production was fraught with challenges. The global K-drama boom had driven up actor fees in South Korea. “Wages for South Korean actors are five times those for their Japanese counterparts with the same skill level,” says an insider on another co-production. Nakajima had to search for a “talented actor who hasn’t yet had a lead role” to keep costs manageable. He found Chae Jong-hyeop, a rising star with limited leading experience but strong screen presence.

Cultural and linguistic misunderstandings also plagued the shoot. Script translations misrepresented nuance, and depictions of Korean lifestyles required constant adjustment. Nakajima held daily huddles with the director and crew to fine-tune scenes. “We even analyzed the visual quality of recent Korean dramas—lighting, color grading, camera work—to ensure our show met the high bar viewers expect,” he explains.

These efforts paid off. The visual polish of Eye Love You helped it compete in a market saturated with slickly produced Korean content. Nakajima is already planning new genre experiments, though he acknowledges that “many ideas simply cannot be developed” under current budget constraints.

A Strategic Alliance: Studios and Streamers Join Forces

The success of Eye Love You has accelerated formal partnerships between Japanese broadcasters and Korean entertainment conglomerates. In May 2024, TBS announced a three-year deal with CJ ENM (the powerhouse behind BTS and Parasite) to produce at least three terrestrial dramas and two films. The agreement covers co-development, casting, and distribution rights.

Similarly, TV Asahi Corp. signed a cooperation agreement with major Korean studio SLL (formerly Studio Dragon) on May 17, 2024, focusing on TV drama development. The terms include shared production resources and cross-border writer exchanges.

Streaming platforms are also jumping in. Netflix revealed on May 31 that it will produce Romantics Anonymous, starring Japanese A-lister Shun Oguri and Korean star Han Hyo-joo (Twenty-five Twenty-one). The project is a direct response to growing demand for pan-Asian content with international appeal.

Other announced collaborations include:

• A South Korean adaptation of the novel Things That Come After Love, co-written by Japanese author Hitonari Tsuji and Korean novelist Gong Ji-young, starring Kentaro Sakaguchi and Lee Se-young.
• An undisclosed project from Tristone Entertainment, the agency representing Oguri and Sakaguchi, leveraging its 50-year network in the Korean industry.

Learning from the Korean Playbook: A New Export Mindset

For Japanese producers, the collaboration offers more than just star power—it’s a masterclass in global marketing. Veteran movie producer Mataichiro Yamamoto, who has cultivated ties with Korea for five decades, notes that “the Korean industry succeeded in breaking racial barriers for Asian creations worldwide.” He believes Japanese content now benefits from the halo effect of Hallyu’s success. “South Korea is our colleague, not our rival.”

Scriptwriter Daisuke Habara (Hula Girls), who serves as Japan’s representative on the Asian TV Drama Conference, observes a fundamental difference in approach. “South Koreans view entertainment as an export industry. They blend Hollywood production systems with uniquely Korean emotions and social issues. That know-how is right at our doorstep,” he says. “For now, the Japanese side should soak up everything thoroughly.”

This learning curve includes adopting Korea’s rigorous pre-production processes, data-driven content testing, and aggressive global distribution strategies. Japanese broadcasters, traditionally focused on a domestic audience, are now eyeing international markets—a shift that could reshape the industry.

The Future of Japan-Korea Co-Productions

As more deals are signed and more bilingual talents are cast, the line between J-drama and K-drama blurs. The collaboration offers mutual benefits: Japan gains access to Korea’s export infrastructure and global fanbase, while Korean actors and creators find new opportunities amid a home market squeezed by rising costs and a plateau in domestic production.

The trend also opens doors for nuanced storytelling. Shows like Eye Love You prove that language itself can be a narrative asset, not a liability. As audiences become more accustomed to subtitles and multicultural casts, the demand for boundary-pushing content will only grow.

For now, the industry watches closely. If these early experiments yield sustained hits, the Japan-Korea co-production model could become a blueprint for Asian content collaboration—proving that sometimes, the best stories are written across borders.
