House of Massage Chairs · Kyota M900 Series
A 4D L-Track chair built around adjustable massage, AI-guided customization, and a control system that lets you move from a preset session to a highly specific one without starting over.

01 · Quick Decision
The reason to choose it is control.
In brief
The Kyota Hatsumei M900 4D AI Massage Chair combines a 4D back mechanism, 44-inch L-Track, Advanced AI TrueFit body scanning, an AI Custom Massage Generator, and 20 automatic programs. Its advantage is control: tune 4D intensity and speed by region, adjust air compression by area, then save preferred sessions. Compare the Genki M380 if you prefer fewer controls.
4D movement
4D depth and variable speed make the roller character more adjustable.
AI workflow
TrueFit scanning and the AI generator create a more specific starting point.
Lower body
Dual foot rollers pair with calf kneading, oscillation, and compression.
Room fit
Zero Wall Fit needs 2 inches behind the chair; reclined length is 74 inches.
02 · How It Works

The Mechanism
4D adjustment along a 44-inch L-Track.
The 4D mechanism adds variable speed to three-dimensional roller movement. Its 44-inch L-Track carries quad rollers from the neck area toward the glutes.
- Mechanism 4D back and glutes
- Track L-Track · 44″
What changesJudge the M900 by actual depth, speed, and roller contact on your body.
The AI Layer
Scan first. Then decide how much control you want.
Advanced AI TrueFit sensors read body shape and micro-tune the 4D mechanism. The AI generator lets you choose techniques, regional speed, 4D intensity, and air pressure by area.
- Body scan Advanced AI TrueFit
- Custom builder Back + air compression
What changesThe AI matters when it helps you reach a repeatable setting faster.
Air + Lower Body
Compression surrounds dedicated foot and calf hardware.
The chair uses 56 air cells in 28 airbags. Dual foot rollers work under each foot while calf kneading, oscillation, and compression add dedicated lower-leg massage.
- Air system 28 airbags · 56 cells
- Feet Dual rollers per foot
- Calves Kneading · oscillation · compression
What changesTest lower-body pressure at low settings; sensitivity varies widely.
The Controls
Preset when you want speed. Manual when you want specificity.
The wired touch screen handles 20 automatic programs, manual controls, the AI builder, and saved favorites. Voice Command and a quick-access panel provide faster adjustments.
- Auto programs 20
- Controls Touch screen · voice · quick access
- Convenience USB charging
What changesThe M900 rewards buyers who will use its customization, not only presets.
Recline + Fit
Three zero-gravity levels, with 2 inches behind the chair.
Zero Wall Fit slides the chair forward while reclining. It still reaches 74 inches reclined. TrueFit sensors automatically size the leg extension.
- Zero gravity 3 levels
- Wall clearance 2″
- Footrest Sensor-guided extension
What changesRear clearance is small, but full room and body fit still need checking.
03 · The Adaptive Routine
The value appears after the first week.
The Hatsumei suits users whose preferred massage changes from day to day. Start with 20 automatic programs, then move to the AI generator or manual settings when you want more control.
Save the combination you want to repeat. That is the practical technology story: presets for speed, detailed control when you want it.
- i. 20 automatic programs Fast starting points
- ii. AI Custom Massage Generator Build a specific session
- iii. My Favorite memory Recall preferred settings
- iv. Lumbar heat Warmth as a comfort feature

The Hatsumei M900 is a wellness and relaxation chair. Evaluate comfort, pressure, and fit as personal preferences rather than as treatment outcomes.
04 · Fit & Personalization
The published range is only the first check.
Kyota lists an ideal height range of 4'8" to 6'2", a 300-lb maximum, 17.5-inch seat depth, 21-inch hip width, and 21.5-inch shoulder width. Use those as screening numbers, then confirm real fit.
Compare body fit in person →Confirm where the rollers and airbags land.
Use the scan, then check neck reach, shoulder contact, and comfortable 4D pressure.
Test calf and foot intensity at low settings first.
Test calf and foot pressure at low settings first; sensitivity varies.
Make sure the interface matches the household.
Try the tablet, voice commands, quick-access panel, and a saved favorite.

What is the current price of the Kyota Hatsumei M900 4D AI?+
The current HMC product page lists the Kyota Hatsumei M900 4D AI at $4,999.00. Because promotions can change, use the live price at the top of the product page as the final purchase price.
What are the Hatsumei M900 dimensions and wall-clearance requirements?+
The chair is listed at 64″ x 32″ x 47″ upright and 74″ x 32″ x 33″ reclined, with 2″ of wall clearance. Measure the full delivery route and the 74-inch reclined footprint, not only the rear wall gap.
What user height and weight range is appropriate for the Hatsumei M900?+
Kyota currently lists an ideal height range of 4'8″ to 6'2″ and a maximum user weight of 300 lbs. Seat, shoulder, calf, and foot fit can still vary within that range, so an in-person fit check is useful.
What massage mechanism and track does the Hatsumei M900 use?+
It uses a 4D back mechanism on a 44-inch L-Track. Kyota describes the fourth dimension as variable speed added to three-dimensional roller movement, while the track carries the quad rollers from the neck area toward the glutes.
What warranty and delivery terms apply to the Hatsumei M900?+
The live HMC page currently lists White Glove delivery as included with an estimated 5–14 business-day window. Kyota publishes a 4-year residential limited warranty structure with 4 years on the structural framework, 2 years on covered parts, and 1 year of Complete Care covered parts and labor. HMC's purchase panel currently summarizes 2-year manufacturer-backed coverage, so confirm the exact warranty terms attached to your order.
What does AI do on the Hatsumei M900?+
Advanced AI TrueFit sensors scan body shape and micro-tune the 4D mechanism. The AI Custom Massage Generator lets you select techniques, adjust 4D intensity, set speed across four track regions, and set air-compression intensity by area.
Before You Decide
Test the controls and the fit, not just the feature list.
Use an in-person comparison to check 4D pressure, shoulder alignment, calf and foot fit, the tablet, voice commands, recline comfort, and ease of entry and exit. Contact HMC to confirm current showroom availability for the Hatsumei M900 before you travel.
