Earthquake-resistant products

We have created a "stability" that has never existed before.Introducing our highly earthquake resistant anti tip device.

We offer earthquake resistant insulators tailored for a variety of applications.
Their outstanding characteristic is a broad compatibility with a wide range of piano manufacturers and models

Fit Board (for upright pianos) – 23 Model.
*Earthquake resistance tested.

A new mechanism has been developed that utilizes the off-centered characteristics of piano casters (the misalignment between the caster’s center of gravity and its steel core)

By rotating the piano casters 90 degrees—installing the front casters facing inward and the rear casters facing outward—we were able to reduce how much the piano extends beyond the Fit Board. As a result, the piano can now be placed closer to the corner of a room than with previous products.

  • • Seismic Performance

    Testing has demonstrated that the piano will not tip over even under a level 6 earthquake

  • • Tone Quality

    Because the board is made of wood, sound from the piano is transmitted directly to the floor, allowing the timbre to resonate more naturally.

  • • Caster Stability

    The Fit Board’s caster receivers are shaped to match the caster’s arc and feature a two step recess, allowing the caster to sit deeply and securely.
    This structure keeps the piano stable.

  • • No Direct Damage to the Piano

    No screws or nails are required. The piano, floor and walls will not be scratched or damaged.

  • • Flexible Placement

    The piano can be positioned in minimal space at home, almost flush against the wall.
    This product is suitable for used in public facilities such as kindergartens and schools, where pianos are often placed away from the wall.

  • • Minimal Caster Lift

    The caster lift is kept to a minimum—approximately 11 mm—so the piano’s pedals can be pressed naturally and comfortably.

  • • Compatible with a Wide Range of Models

    With its stepless adjustable function, the Fit Board can be installed with most pianos, regardless of manufacturer.
    * Some models may not be compatible (e.g., pianos with double casters).

Provides firm support while preventing any damage to the piano.

The Fit Board is easily adjustable, allowing it to be used with almost any piano. Once installed, the piano’s front and rear casters are secured together with the Fit Board, compensating for the weakness of pianos that tend to sway backward and forward.
