CHOICES,
NOT
BOUNDARIES

We open up the digital frontier
and create "choices beyond boundaries."

With 3D, 4D, and AI, we preserve culture, protect infrastructure,
and turn places into experiences.

ABOUT

BEYOND
Real & Digital
BORDERS

Crossing the border between real and digital,
we expand the value each can create.

With 3D Gaussian Splatting (3DGS) and 4DGS at its core, IZUTSUYA Inc. digitizes things that exist in the real world in 3D and 4D. Combining that data with AI, we open up new possibilities, both real and digital, in three fields: culture, infrastructure, and entertainment.

OUR BUSINESS

Culture, infrastructure, and entertainment. We run three businesses built on 3D, 4D, and AI.

Culture Business area

From scanning to archiving, publishing, and distribution. We handle it all, end to end.

  1. ScanCapture in 3D and 4D
  2. ArchivePreserve and protect
  3. PlatformPublish and deliver

  • 3D & 4D scanning

    Buildings, crafts, and plants, recorded with the light around them.

    Gaussian Splatting is our core, combined with DSLR cameras, 360° cameras, and laser scanning such as LiDAR, as the subject requires. We also handle data-size reduction for publishing and mesh conversion.

  • Cultural heritage archiving

    Record it before it is lost, as data that can be handed down.

    Buildings, craft objects, the formal gestures of traditional arts. From recording and preservation to publishing and use, in one workflow. Pictured: a 3DGS capture of Umayaguchi Gate, Ako Castle.

  • 3D data platform: 3Dasset.io

    Publish, embed, store, and sell 3DGS,
    all in the browser.

    Supports the seven major 3DGS formats (PLY, compressed PLY, SPLAT, KSPLAT, SPZ, SOG, and RAD), with license management, website embedding, and marketplace sales.

    Open 3dasset.io

  • New spatial video and streaming platform: 4DGS.jp

    Preserve the motion itself,
    and replay it from any angle.

    Traditional performing arts, craft skills, stage performances. Our 4DGS Viewer is available free of charge.

    Open 4dgs.jp

Infrastructure Business area

Point clouds and AI make inspection faster and more reliable.

  • LiDAR Damage Detection

    AI detects cracks, spalling, and exposed rebar.

    We combine LiDAR point clouds with image-recognition AI to support the whole process, from detecting damage to generating inspection reports. In beta.

  • Point cloud × BIM × 3D/4D Gaussian

    From a single capture, data for both digital construction and PR.

    A single capture yields a LiDAR point cloud, BIM, and 3D/4D Gaussian data. We choose the right tool for the purpose, from our own LiDAR scanner (3DMakerpro Eagle) to our partners' industrial LiDAR systems.

Entertainment Business area

Turn the place itself into an experience.

  • Location-based XR

    Walking becomes the experience.

    XR experiences that combine place and human movement. From planning and 3D capture of places and people through to development and operation. The titles we are involved in will be announced one after another, starting in the second half of 2026.

  • Motion capture and IP

    100+ people at once, with no markers.

    AR51 turns movement into data. We capture dance and traditional gestures as motion data, and go on to produce games using assets captured from the real world.
