Japan's connected TV advertising landscape in 2026 continues to expand rapidly, driven by high smart TV penetration and shifting consumer viewing habits. Brands are allocating more budgets towards CTV to target tech-savvy audiences, with significant growth in ad spend and campaign volume. The high engagement levels suggest CTV will become a dominant channel for digital advertising in the country.
