Format

One of the freshest and most compelling of competition shows is undoubtedly the Japanese format Kasso, produced by TBS (Tokyo Broadcasting System) and on the air since 2023. True to its title (kasso 滑走 literally means “to glide” or “to slide” in Japanese), the format blends the country’s distinct mastery of the genre (who could forget TBS’s own iconic Takeshi’s Castle and Ninja Warrior - Sasuke?) with the world of skateboarding.

A curated lineup of top domestic and international skaters takes on a massive outdoor course divided into three main stages. It is not just about landing high-scoring tricks; it is about surviving video-game-inspired time trials where speed, balance, and risk management are everything. Following two preliminary rounds (Midoriyama/Downhill and Uzushio/Vortice), the competition culminates in the spectacular finale: Tokyo Upside-Down. This stage features a massive, 180-meter-long, three-story vertical structure packed with highly challenging geometric obstacles. Skaters who cross the finish line within the time limit walk away with a substantial cash prize.

The format was an instant hit, quickly expanding into multiple seasons and special installments in Japan. However, Kasso’s true standout feature is its distribution strategy. TBS immediately launched an official YouTube channel, uploading full episodes with English subtitles, racking up millions of views, and directly tapping into the global skate community.

Furthering this momentum, TBS Games rolled out the official mobile spin-off this past February, Kasso Gaiden: Escape from the Skaterverse, which was equally well-received by core fans.
Building on these digital successes, the IP has now successfully transitioned into the real world. The format made its physical US debut with the Kasso Fest Skate & Sound in Long Beach, California. The two-day festival (held on March 21–22) combined a live music lineup with a game-show-style skate competition, drawing over 4,000 fans.

While the festival was initially livestreamed via Red Bull TV, the definitive “Original TV Edit” is making its official YouTube premiere this summer. Following the release of Day 1 in late June, the highly anticipated Day 2 is set to premiere on the platform today July 3rd. This episodic YouTube rollout features exclusive, re-edited content not seen in the original live broadcast.

All in all, Kasso stands as a textbook example of a great format backed by a cohesive, multi-platform, and genuinely innovative brand expansion.
