What Makes the Kyota Hatsumei M900 AI Different?
The Hatsumei M900 AI is built around personalization.
Instead of relying only on preset massage programs, the AI Custom Massage Generator lets you adjust massage technique, 4D intensity, speed across four regions of the massage track, and air-compression intensity for individual body areas.
Patented AI body scanning also detects the user's shape along the back and fine-tunes the 4D mechanism for more consistent positioning.
Why Choose the Hatsumei M900 AI?
AI Custom Massage Generator
Build highly customized massage routines using technique, 4D intensity, speed, track regions, and air-compression settings.
Patented AI Body Scanning
Advanced sensors detect body shape and help fine-tune the 4D massage mechanism.
20 Automatic Programs
A large selection of choreographed programs provides quick one-touch sessions.
4D Back & Glute Massage Mechanism
The Hatsumei uses an advanced 4D massage mechanism that moves:
Up and down
Left and right
In and out to adjust massage depth
At variable speeds
These movement options allow the chair to create a more varied massage experience than a conventional fixed-depth mechanism.
Extended L-Track Massage Coverage
The Hatsumei's L-Track carries the quad massage rollers from the neck down through the back and into the glute area.
This extended path provides broad roller coverage during both automatic and customized massage sessions.
AI Custom Massage Generator
The AI Custom Massage Generator is the defining feature of the M900 AI.
Users can customize:
Massage technique
4D massage intensity
Massage speed
Four separate regions along the massage track
Individual air-compression areas
Air-compression intensity
Customized routines can then be stored in memory for easier repeat use.
Patented AI TrueFit Body Scanning
Patented AI sensors detect body shape at multiple points along the back.
The chair then fine-tunes the 4D mechanism to better match the individual user's position.
56 Air Cells Across 28 Airbags
The Hatsumei uses 56 air cells integrated into 28 airbags for compression massage across multiple body zones.
Adjustable shoulder airbags are also included as part of the chair's customizable air-compression system.
Calf Kneading, Oscillation & Compression
The Hatsumei combines mechanical calf movement with oscillating rubbing and air compression.
This creates a more active lower-leg massage than an air-only calf system.
Double Roller Foot Reflexology
Each footwell includes two shiatsu rollers beneath the sole.
These provide focused roller coverage across the feet during full-body sessions.
Zero Gravity & Zero Wall Fit
Weightless Zero Gravity
Zero Gravity recline places the body in a supported position during massage.
Space-Saving Zero Wall Design
The chair slides forward while reclining to reduce the amount of room needed behind it.
TrueFit Automatic Footrest Extension
Advanced sensors automatically adjust the footrest length based on the user's leg position.
This helps the chair accommodate users across its recommended height range.
Lumbar Heat
Heating modules in the lower-back area provide gentle warmth during massage sessions.
Heat can be combined with automatic programs, custom AI routines, Zero Gravity, and air compression.
Touchscreen, Quick Access & Voice Control
Touchscreen Controller
Navigate automatic programs, manual settings, and AI customization through the touch interface.
Quick Access Controls
Chair-side buttons provide convenient access to frequently used functions.
Intelligent Voice Command
Compatible functions can be activated with hands-free voice commands.
Bluetooth Audio & USB Charging
Built-in Bluetooth speakers allow users to stream music, podcasts, or other audio from a compatible device.
A USB charging port is integrated into the quick-access control area.
20 Automatic Massage Programs
The Hatsumei includes 20 automated massage programs.
Each program combines massage techniques, intensity changes, air compression, and chair movement into a complete session.
