Who They Help

SAI Inc. primarily serves B2B companies, government entities, and cultural organizations that need to communicate across borders.

The agency also produces other-language versions of existing videos, ensuring consistency in messaging while adapting to cultural nuances. SAI Inc.’s in-house studio in Minato City enables efficient production cycles, from narration recording to video editing, without outsourcing key steps.
