Fit: The Biggest Difference
The two chairs cover very different height ranges. The Kansha M878 lists 5'2" to 6'9". The Hatsumei M900 lists 4'8" to 6'2", which suits shorter users. Both list a 300 lb. recommended weight.
If the tallest person in your home is over 6'2", the Kansha is the one that lists their height. If the shortest user is under 5'2", the Hatsumei is the one that fits.
Massage Mechanism and Track
Kyota Kansha M878
The Kansha uses a 4D mechanism on a 49-inch L-Track that runs from the neck down under the seat to the glutes. Its product page lists 5 intensity, 6 speed and 3 width settings, along with a body scan at the start of each program. You get nine automatic programs and two memory slots.
Kyota Hatsumei M900 AI 4D
The Hatsumei also uses a 4D roller, on an SL-Track. Its product page lists an AI body scan, 20 automatic programs, manual programs, deep tissue and stretch programs.
Air, Heat and Lower Body
The Kansha lists 32 airbags with 54 air cells covering the shoulders and arms, back and waist, legs and feet, and buttocks, with five levels of independent adjustment. For the lower body, it has calf rollers, calf oscillation and triple-roller foot reflexology.
The Hatsumei lists 28 airbags covering the shoulders, arms, waist, seat, calves and feet, plus kneading calf massage and foot rollers. Both have lumbar heat.
Space and Delivery
The Hatsumei needs less room. It lists 2 inches from the wall to recline and measures 74" long reclined. The Kansha needs 4 inches from the wall and measures 80" long reclined.
The Kansha is also heavier, at 328 lbs. (404 lbs. shipping weight), compared to 249 lbs. for the Hatsumei. The Hatsumei lists a 31" minimum door width. Shipping is free to the contiguous U.S. (48 states). See shipping information for delivery options.
Controls and Extras
The Kansha has a color LCD handheld remote, 15 voice commands, an Apple and Android app, Bluetooth speakers, a USB port and an air ionizer. The Hatsumei uses a touchscreen tablet with quick controls, voice control, Bluetooth speakers and USB charging.
Which Kyota Should You Choose?
Choose the Kansha M878 if...
You're tall (up to 6'9" listed), want calf rollers and oscillation, prefer an L-Track that reaches the glutes, or want the lower price.
Choose the Hatsumei M900 if...
You're on the shorter side (from 4'8" listed), want more automatic programs, need a chair that sits closer to the wall, or prefer a touchscreen tablet.
Programs in Detail
The Kansha's nine automatic programs include Stretch, Night, Upper Body and Lower Body, plus 4D programs such as Yoga, Deep and Kneading. Its two memory slots let you save your own settings. The Hatsumei's 20 automatic programs include deep tissue and stretch options, and it also offers manual programs if you'd rather set the rollers yourself.
Delivery and Assembly
Both chairs ship by freight with free curbside delivery to the contiguous U.S. (48 states). The Hatsumei ships in two boxes, listed at 58"L x 31"W x 27"H and 47"L x 17"W x 29"H. The Kansha lists a 404 lb. shipping weight, so you'll want extra help. Assembly is required and can take 30-90 minutes, depending on the chair. If you'd rather not handle it yourself, In-Home Delivery and Assembly is available for an added fee.
The Bottom Line
Fit and space decide this one. The Kansha suits taller users and anyone who wants calf rollers and an L-Track. The Hatsumei suits shorter users, tighter rooms and buyers who want more programs. Both carry a 4-year limited warranty.
