Japan's Massive Spy Thriller VIVANT Smashed Local Ratings But Flopped Worldwide — Here's Why Korea Wins the Global Hit Game

TBS’s blockbuster spy drama VIVANT just crushed streaming charts across Asia, pulling in an estimated 15.63 million unique viewers in August 2026. But there’s a massive catch: 15.13 million of those viewers—a staggering 97 percent—were locked right inside Japan. While the show is an absolute titan locally, it barely made a blip overseas, dragging up a painful question for Japanese producers: why can South Korea churn out global TV hits like Squid Game while Japan stays trapped in its own bubble?

Why Japan's Huge Domestic Market Keeps Shows Locally Trapped

According to media expert Toshihiko Tabuchi, writing for President Online, the root of the problem is a giant paradox. Japanese television networks don't need international streaming rights to survive because their home audience is still big enough to fund massive budgets through domestic advertising and local platforms like TVer. VIVANT pulled over 10 million views domestically on TVer alone, dwarfing its numbers on global services like Netflix or Prime Video.

Because the local market is so comfortable, Japanese networks fund shows specifically for Japanese tastes rather than designing them to appeal globally from day one. South Korea, on the other hand, has a much smaller home market. That forced Korean studios to build shows for international audiences and global streaming platforms from the very beginning, turning K-dramas into an unstoppable worldwide phenomenon while Japanese live-action exports sit at just 2% of total overseas sales.
