What Welt does

Welt Co., Ltd. (ヴェルト株式会社) is a Tokyo-based, privately held video post-production company founded in 1991 and led continuously by founder-CEO Yasui Junji. The company provides professional non-linear video editing, audio mastering (including 5.1ch surround), digitization, archiving, and offline editing services for television programs, internet broadcast content, and corporate videos. Operations are centered on four strategically located video production facilities across Tokyo — the 9-floor Shiodome Video Center (headquarters), Daiba/Diversity Video Center, Shibuya Video Center, and the Roppongi Video Center operated by wholly-owned subsidiary TSP-WARP — equipped with Adobe Creative Cloud, DaVinci Resolve, EDIUS, Pro Tools, Avid Media Composer, TFX-Artist telop systems, and hybrid linear/non-linear switching infrastructure.

Welt's go-to-market is a B2B enterprise field-sales model serving major Japanese broadcasters and streaming platforms, with quote-based project pricing and no consumer-facing products. The named customer base includes every major Japanese network — NHK (including NHK WORLD-JAPAN), Nippon TV, TBS, Fuji TV, TV Asahi, TV Tokyo, WOWOW, BS11 — as well as streaming platform AbemaTV, covering variety shows, news, documentaries, music programs, sports, and special broadcasts. The company maintains dedicated mid-career and new-graduate recruitment pipelines to staff technical editor and designer roles across its centers.

The business operates as a professional-services revenue stream from broadcast post-production, with reinvestment focused on facility renewal (Shiodome floors 4/8/9 renovated between 2021 and 2023), 4K and hybrid editing capability expansion, and incremental streaming-platform onboarding. Group structure comprises TSP-WARP Co., Ltd. (wholly-owned, established August 2019) and group company Ride Co., Ltd., with a stated paid-in capital of ¥30M and 170 employees across the group.

Direct peers

• ACT Holdings: Broadcast services group offering post-production, media management, content distribution, and broadcast engineering in Japan. Operates adjacent facility-based services for the same broadcast client base as Welt.
• IMAGICA GROUP: Japan's largest post-production group offering video editing, color grading, audio post, and VFX for broadcast, film, and streaming clients. Operates multiple facilities serving the same major Japanese broadcasters as Welt, making it the most directly comparable peer.
• Sogo Vision: Tokyo-based post-production house providing video editing, audio post, and finishing services to Japanese broadcast and film clients. Similar in scale and customer focus to Welt.
• Sony PCL (Post Production Center Linkage): Sony-owned post-production subsidiary providing video editing, digital intermediate, audio post, and finishing services for broadcast and film in Japan. Competes directly with Welt for major TV network post-production contracts.

Broad incumbents

• IMAGICA SDI Group: Pre-consolidation post-production subsidiary within the IMAGICA GROUP, providing video editing, color grading, and audio services for broadcast and film. Now part of the broader IMAGICA GROUP but historically competed as a standalone specialist comparable to Welt.

Others

• For-A Co., Ltd. Japanese manufacturer of broadcast video equipment (switchers, signal processors, character generators) and provider of broadcast systems integration. Supplies the kind of equipment (e.g., MVS-series switchers) that Welt uses in its facilities, making it an adjacent ecosystem participant rather than direct competitor.
• Techno Media: Broadcast technology and services provider in Japan offering video processing, media asset management, and content distribution infrastructure. Adjacent to Welt's broadcast post-production business but focused on technology enablement rather than direct facility-based editing services.

Emerging players

• Omnibus Japan: Japanese post-production and dubbing company with emphasis on localization, voice-over, and content adaptation. Comparable in post-production service model but more focused on dubbing/localization than Welt's broadcast editing focus.
