What （株）東京サウンド・プロダクション does

Tokyo Sound Production Inc. (TSP) is a privately held Japanese post-production company founded in 1959 and headquartered in Nishi-Azabu, Minato-ku, Tokyo, where it operates physically inside TV Asahi's broadcast facility. The company delivers a one-stop audiovisual production service spanning six integrated disciplines: production planning (制作), professional filming (撮影), video editing (映像編集), sound effects (音響効果), multi-audio/mixing (MA), and broadcast technology (放送技術). Its technical stack includes 4K UHD and HDR finishing via Quantel Rio and Mistika systems, Dolby Atmos 9.1.4ch immersive audio mixing, LTO 6 long-term archival infrastructure, and remote MA delivery via ZOOM, supporting Japan's 4K/8K broadcast transition mandated by the Ministry of Internal Affairs and Communications.

TSP serves three primary customer segments: TV broadcasters and networks (anchored by TV Asahi with daily program support for Music Station, Ametalk, London Hearts, Aiba Manabu, and other flagship shows, plus NHK and ABEMA work); entertainment and performance companies (notably Tokyo 03 comedy troupe across 28 solo performances, HYDE music videos, and concert recordings); and corporate/brand clients (Kirin Brewery CMs and similar advertising production). Revenue is generated primarily through project-based professional services contracts, supplemented by sound effects library sales through the Audiostock marketplace and direct DVD sales. The company's competitive position rests on its deep operational integration with TV Asahi's broadcast workflows, a specialized talent base including Grammy-associated mixing engineers and veteran camera operators, and an internal TSP Awards recognition program running continuously since 2001.

The business operates exclusively within the Tokyo metropolitan area with no evidence of international geographic expansion. There are no disclosed funding rounds, M&A activity, parent company, or external investors; TSP appears to be founder- or internally-managed. No AI/ML capabilities are part of the disclosed product offering, and the technology strategy centers on conventional craft-based post-production infrastructure rather than automation or proprietary software platforms.
