Osaki | Model JP-Nexus 4D

Osaki JP-Nexus 4D Massage Chair

The Osaki JP-Nexus 4D is a 4D massage chair, which means its rollers vary both depth and speed inside a single stroke, and Osaki builds it in Japan for quiet running. A noise reduction system makes it a Quiet Massage Chair, which matters in a room where someone else is reading. Sixteen auto programs sit alongside 35 manual programs for a total of 51, and 35 manual programs is the deepest library Osaki puts in a chair of this size. It needs only 3.5 in. behind the backrest for a full recline.

Those 35 manual programs are where the JP-Nexus separates from the chairs beside it. An auto program runs a fixed sequence from beginning to end. A manual program hands you the technique, the zone and the intensity, so you can work one part of your back the way you want it worked on a given day. Around them sit the parts Osaki build for the extremities. Reflexology is the practice of pressing specific points on the sole of the foot, and the JP-Nexus puts the same idea in the armrests as hand reflexology nodes for your palms and fingers. Underneath sit a memory foam kneading foot massage and specialized foot rollers with reflexology ridges. An airbag is the bladder that inflates and deflates to squeeze a limb, and airbag compression is what works your calves in the calf rests. Thirty-four air cells cover your body for full body air massage, and graphene heating warms your lumbar. The 4D massage mechanism runs on a laser-crafted steel SL-track from your neck and shoulders to your hamstrings, where an S-track would finish at the waist. That extended shape keeps a stroke going under your glutes. The JP-Nexus is rated to a 250 lb user and needs 3.5 in. of clearance behind it. Zero gravity is the recline that lifts your knees above your heart, and this chair stores two stages of it.

How it works

Osaki build the JP-Nexus in Japan around two things most chairs at this level treat as secondary: how quietly it runs, and how much of the massage you get to control.

35 Manual Programs and 16 Auto
Fifty-one programs in total, and the balance between them is what marks this chair out. An auto program picks the sequence for you and runs it start to finish. A manual program hands the technique, the zone and the intensity back to you. Thirty-five of them is the deepest manual library Osaki fit to a mid-tier chair. It puts the shape of a session in your hands on the days when no preset is quite what you were after.
51 programs
Noise Reduction
Osaki call the JP-Nexus a Quiet Massage Chair and fit a noise reduction system to hold down the sound the mechanism makes while it runs. A quiet chair is worth looking for when the chair lives in a shared living room. It gets used in the evening, while other people are watching something or reading in the same space.
Quiet running
Hand Reflexology in the Armrests
The armrests carry acupuncture hand reflexology nodes: small raised points that press into your palms and fingers while your arms rest in place. Hands are within a massage chair's reach, and most chairs wrap the arms in airbags and leave the hands out of it. On the JP-Nexus your hands are worked at the same time as your back.

What the 4D Mechanism Adds
A 2D roller is the simplest kind, moving up, down and across. A 3D roller adds depth, which means it pushes further into your back or eases off it. A 4D mechanism adds the fourth variable, rhythm: the speed of the roller changes through a single stroke, so the pressure builds and eases while the head is still traveling. Thirty-five manual settings are worth having on a mechanism with that many things to vary.

The back

A Laser-Crafted Steel SL-Track

Osaki make the JP-Nexus SL-track from laser-crafted steel and run it from your neck and shoulders through to your hamstrings, carrying the 4D massage mechanism the whole length. An automatic body scan reads you before a program starts and sets the roller positions from what it finds. Graphene heating warms the lumbar section, so your lower back is warm while the rollers work through it, and 34 air cells squeeze your body around the track.

  • Laser-crafted steel SL-track system
  • Coverage from the neck and shoulders to the hamstrings
  • Automatic body scan before the program starts
  • Graphene lumbar heating therapy
  • 34-cell full body air massage

Memory Foam Shapes Itself Around Your Foot

The JP-Nexus works your lower leg three ways at once. Memory foam in the footrest shapes itself around your foot and applies force through it for the kneading foot massage. Specialized foot rollers underneath carry reflexology ridges that press the acupuncture points on your soles. The calf rests use airbag compression for the deep calf kneading. The whole footrest extends up to 5 in. on its own, which is the adjustment that sets all three to the length of your legs.

  • Specialized foot rollers with reflexology ridges
  • Deep calf kneading by airbag compression
  • Automatic extendable footrest, up to 5 in.

Living with it

The Parts You Touch Every Session

Three separate controls run the JP-Nexus 4D, and each of them has a job. The touchscreen controller is where the 51 programs live. Shortcut panels in the side of the armrest handle quick changes mid-session without opening a menu. Intelligent voice control covers the same commands when you are reclined and your arms are down in the reflexology armrests. The headrest lifts out, which brings your shoulders closer to the rollers for a deeper massage, and LED lighting sets the room around the chair.

  • Touchscreen controller holding all 51 programs
  • Shortcut panels in the armrest for changes mid-session
  • Intelligent voice control for spoken commands
  • Removable headrest for a deeper massage at the shoulders
  • Bluetooth speakers and LED lighting

Questions

Frequently asked questions

An auto program is a full session already sequenced: press it once and the chair works through its own order of techniques and zones. A manual program is a single setting you choose and hold. The JP-Nexus carries 16 auto and 35 manual, so 51 in total. The manual count is the unusual one at this size of chair, and it suits somebody who already knows which technique they want and where.
Japan. Osaki build the chair there and design the whole model around Japanese craftsmanship. The quiet running and the hand reflexology in the armrests both come out of that.
Osaki fit a noise reduction system and call the JP-Nexus a Quiet Massage Chair. The system holds down the sound the mechanism makes while it operates. How loud that leaves it depends on the program and the room, so treat it as a design priority rather than a decibel figure.
The armrests carry acupuncture hand reflexology nodes. They are small raised points positioned where your palms and fingers sit, and they press into your hands while your arms rest in the armrests. Most massage chairs compress the arms with airbags and leave the hands alone.
The lumbar, using graphene heating, which is the one heated zone on the JP-Nexus, and the warmth sits at your lower back while the rollers pass through it. If you want heat in more places, the Osaki OS-Highpointe 4D heats the lumbar, the calves and, through a shawl, the chest and stomach.
Three things. Memory foam in the footrest applies force around your foot for the kneading foot massage. Specialized foot rollers with reflexology ridges work your soles. Airbag compression in the calf rests handles the deep calf kneading. The footrest sets itself to your leg length first.
Up to 5 in. The automatic extendable footrest moves out on its own to suit different heights and body types. That travel puts the foot rollers under your arches and the calf airbags on your calves.
The JP-Nexus has 2-stage zero gravity, giving two stored recline positions with your knees raised. Space-saving technology is the design that slides the seat base forward as the backrest goes down, so the chair needs only 3.5 in. behind it to reach a full recline.
Taking the headrest out brings your neck and shoulders closer to the rollers for a deeper massage. Leaving it in place softens the contact. It is the simplest intensity adjustment on the chair and it costs nothing to try both ways.
Three ways: a touchscreen controller for the full program list, shortcut panels in the side of the armrest for quick changes mid-session, and intelligent voice control for spoken commands. An automatic body scan runs first and sets the roller positions for whoever is in the seat. The heads travel your back once to find your shoulder height and the length of your spine. The program that follows is mapped onto those points.
Upright it is 33 by 63 by 49 in. (W by L by H). Reclined it is 33 by 70 by 41 in. Minimum doorway is 33 in. With space-saving technology the chair needs only 3.5 in. of clearance behind it, because the seat base travels forward as the backrest goes down. The growth from 63 in. to 70 in. happens on the floor in front of the chair, and the headrest stays close to the wall.
Maximum user weight is 250 lb. Shoulder width is 22 in. and seat width is 16 in., the narrow end of the Osaki line and a compact fit. The Osaki Atlas XL 4D runs a 23 in. seat and 26 in. shoulders on a frame built for a larger body.
The auto timer is 20 minutes. Power is a standard household supply of 110 to 120 V at 50/60 Hz.
Bluetooth speakers for surround sound audio, LED lighting around the chair, and the shortcut panels and removable headrest.
