TOHO Cinemas Oimachi Opens March 28 With Tokyo’s First TOHO Dolby Cinema Installation

From a technical standpoint, the most interesting aspect of the Oimachi complex is how TOHO differentiates its in-house formats rather than relying solely on Dolby branding. The Premium Theater’s TCX screen is not just a size play; it’s paired with a speaker layout tuned to the room geometry, suggesting deliberate control over dispersion and phase alignment rather than a generic cinema preset. This kind of venue-specific calibration is closer to what audiophiles would expect from a purpose-built listening room, prioritizing tonal balance and transient precision across a wide seating area. Compared to standard multiplex auditoriums that often favor sheer SPL, the emphasis here appears to be on maintaining clarity and bandwidth consistency regardless of seat position.

The so-called “Goon-on” Theater takes a more aggressive approach, and its disclosed hardware choices are telling. A large-format 3-way main system combined with isobaric subwoofer loading points toward a design aimed at reducing enclosure distortion while increasing effective acoustic output. Isobaric configurations are rarely seen in cinemas due to cost and complexity, but they offer tighter low-frequency control when executed properly. Paired with 3-way surround channels rather than simpler 2-way effects speakers, the system suggests an intent to preserve midrange articulation even during high-energy scenes—something action-heavy mixes often lose in conventional rooms.

What’s notable across these formats is a philosophical split that mirrors debates in enthusiast circles: spectacle versus fidelity. Dolby Cinema leans into reference-grade contrast and object-based immersion, while TOHO’s proprietary theaters explore how far room-specific engineering can push perceived realism without leaning on external standards. For listeners who pay attention to crossover behavior, bass integration, and spatial coherence rather than just loudness, Oimachi quietly positions itself as a case study in how modern cinemas can evolve beyond uniform, one-size-fits-all sound.
