Product Description


  • Made in Japan: The quality of the components and engineering that goes into a Japan-made massage chair are generally far superior compared to chairs manufactured in China. The rigorous quality control paired with the excellent workmanship results in a longer lifespan. The Osaki-JP Premium 4.0 is not only manufactured in Japan but is backed by Fuji Medical, one of the most renowned massage chair brands in Japan. Through Fuji Medical’s partnership with Osaki, the Osaki-JP Premium 4.0 is now available in the U.S. for the first time
  • 4D Roller System: The Osaki-JP Premium 4.0 offers an exceptional human-like roller massage in the backrest of the chair. Spanning 30″ in length, this model methodically targets areas of the neck, shoulder line, and back more effectively than Chinese-made chairs. Its sophisticated roller track travels from the base of the skull down past the tailbone, effortlessly massaging traditionally hard-to-reach areas. The Osaki-JP Premium 4.0 comes equipped with a powerful 4D roller track which permits the user to adjust the intensity of the roller heads up to 9 levels — with the ability to extend into the back up to nearly 5 inches — making anywhere from a mild to true deep tissue massage possible
  • 36 Airbags: Air compression bags complement the roller system to make the Osaki-JP Premium 4.0 a full body massage chair. They are distributed throughout the chair to massage the outer shoulders/upper torso, arms, waist, glutes, calves, and feet. Unique to this model is the ability to select different airbag modes, including Pulse Mode, Normal Mode, and an invigorating Hand Kneading function. The strength of the airbags can be adjusted up to 5 levels, which makes fine tuning easy
  • Advanced Body Scanning: The Osaki-JP Premium 4.0’s intelligent “Double Sensing” body scan will perfectly tailor the massage to your unique body shape regardless of your height and weight. During its two step approach, the rollers first travel up and down the back to map your spine. While this is occurring, the embedded computer will detect your shoulder line and neck. Based on this information, the rollers will know where to massage — and where not to
  • Two Heat Sources: Two heat elements are located in the upper torso near the shoulders and on the bottom of the foot soles. Heat therapy has been found to melt away muscle tension, increase circulation, and boost immunity. In a massage chair, heat therapy also allows the rollers to penetrate into the muscles more easily
  • 8 Auto Programs: The Osaki-JP Premium 4.0 offers four auto programs, including Whole Body, Shoulder, Waist, and Stretch. The programs have two intensity variations: Relax and Extreme Mode. Relax Mode will provide a mid-deep massage strength, whereas Ex-Mode results in a deeper tissue massage action

Choose from 17 different advanced massage techniques, including Shiatsu, Looping, Tapping, Stretching, Shoulder Blades, Sciatica, and many more. While four auto programs are available to enjoy if you prefer a one click approach, to fully immerse yourself in the sheer host of massage types available in this model, the manual massage techniques will be more beneficial to most users. With 85 different massage combinations available, directing the 4.0 where and how to massage gives you more control than ever before
  • Multiple Stretch Programs: The roller heads utilize advanced techniques to stretch the neck, back and waist in a way that only a Japan-quality chair can
  • Fine Tuning: Choose from nine 4D roller intensity settings, adjust the width of the rollers up to three levels, the speed of the rollers up to four levels, the airbag intensity up to five levels, choose from three airbag modes, independently adjust the recline pitch of the backrest and footrest, select from 17 massage techniques, choose regional areas of the body you want to target, and much more using the remote control.

4D Roller Technology – Up to 9 Levels

The Made in Japan Osaki-JP Premium 4.0 has many stand-out features, but among the top of the list is its exceptional human-like roller technology. A Japanese-quality chair is unique in its ability to dig into the shoulder blades, neck, and back more effectively than their Chinese counterparts.

The Osaki-JP Premium 4.0’s new 4D roller technology offers users the ability to manually select how far the rollers dig into the back. The 4D system massages side to side, up and down, and in and out. 4D technology also introduces a new speed component which mimics the life-like style of a human massage therapist. The 4.0 has a 30″ track, which massages from the nape of the neck down past the tailbone.

The Osaki-JP Premium 4.0’s 4D system has the capacity of an industry-leading 4.92 inches (12.5 cm), making this model one of the best deep tissue chairs on the market. But it’s not just a chair for users who prefer deep tissue massages. It’s equipped with 9 roller intensity settings — from weak to deep tissue — making it the perfect chair for users who enjoy anywhere from a mild to true deep tissue massage. Simply increase or decrease the roller intensity on the remote control during your massage session to set the firmness of the rollers depending on your level of tolerance.

Double Sensing Body Scan

The Osaki-JP Premium 4.0 integrates two innovative “Double Sensing” body scanning sensors to personalize the massage for your unique body frame. During the first stage, the rollers map your spine’s curvature. During the second stage, the body scan detects your shoulder line relative to your neck and head. The chair makes micro adjustments based on your body type and accurately detects an ideal roller start point on the top of the neck.

If you find that the roller position start point is too high or low, you can override the scan’s results and higher or lower the start point after the body scan has completed.

Double Heating

The Osaki-JP Premium 4.0 boasts two infrared heating sources built into the chair. The first is located in the shoulder area, which is where most tension is formed, making massaging the area difficult. The incorporation of a heat element higher up in the backrest of the chair solves this problem, especially when you consider that Japanese chairs provide an exceptional shoulder blade massage.

The second heat element is located on the bottom of the footrest. This mild heat source warms up the soles of the feet to alleviate any tension as the airbags wrap around the feet.

Triple Mode Airbag System

The Osaki-JP Premium 4.0 includes 36 air compression bags that are strategically placed throughout the chair to ensure everything from the neck down to the soles of the feet are massaged. The airbags massage the outer shoulders, legs, calves, hands and arms, inside the seat, and the waist/pelvis area.

The Osaki-JP Premium 4.0 has an intelligent airbag system that allows you to choose what type of airbag massage you prefer, instead of just one uniform airbag mode for most other models. They include a Hand Knead Mode for the hands and arms; a Pulse Mode to support the promotion of blood circulation by repeating the air supply and depleting little by little; and a more traditional Normal Mode, which focuses the position and massage by repeating the air supply and depleting largely. Pulse Mode and Normal Mode can be selected for any of the airbags, whereas Hand Knead Mode is exclusively for the arms and hands.

There are five intensity levels for the airbags, from weak to strong.

Shoulder Airbags

The Osaki-JP Premium 4.0 features two large air compression bags located behind the shoulders. The airbags inflate on the back of the shoulders, lifting the shoulders up and twisting the body from side to side when they inflate independent of each other, creating an enjoyable deep stretch.

Waist & Pelvic Airbags

Located on both sides of the seat base, two airbags target the hard-to-reach hip and pelvic muscles. The waist airbags are designed to hold the user in place and stretch the hip muscles.

Airbags are also located inside the seat, inflating upwards into the backrest of the chair, to reach the pelvis and gluteal muscles. Combined, the one-two-punch of airbag technology in the waist and around the glutes reduces lower back pain and improves hip mobility.

Arm Airbags

The Osaki-JP Premium 4.0’s armrest pockets offers a unique butterfly-style design which aligns the arms in a more comfortable position compared to other massage chair models. When inserting your arms into the arm panel flaps, the airbags inflate and contour around the arms, palms and hands to provide a relieving, kneading-style compression application.

Foot and Calf Air Massage

Down in the footrest of the chair, the airbag system has been newly improved to massage the calf and foot muscles more accurately. Around the legs, the airbags grip the calves and slowly increases the amount of air that flows into the airbags, stimulating the acupuncture points. Down in the wells of the ottoman, the airbags press down on the feet, putting them into closer contact with the sole nodes. This comprehensive massage will leave your legs and feet feeling revitalized after just one session.

9 Auto Programs

The Osaki-JP Premium 4.0 has four auto courses: Whole Body, Shoulder, Waist, and Stretch. Each of those auto programs has two massage intensity variations: Relax and Extreme Mode. Relax Mode results in a gentler roller massage, whereas Extreme Mode (or Ex-Mode) results in a deeper tissue massage.

17 Manual Kneading Functions

The Osaki-JP Premium 4.0 excels in its ability to offer in-depth approach to massaging the neck, shoulder, waist and back unlike any other model on the market. This model incorporates 17 kneading massage styles and adjustments that can be performed during each technique.

choose from one of these 3 shipping options:

1) Curbside Shipping - FREE

All of our massage chairs qualify for free curbside delivery, which typically ships within 1-3 business days of placing your order. Once the chair arrives at your local delivery terminal, the delivery company will give you a call to arrange a delivery window. Please note that the delivery person is not responsible for carrying the chair into your home, though they may if you ask them to do so. Also note that depending on the chair you are purchasing, it will arrive unassembled. Assembly instructions are included in your chair’s packaging and can be installed in about 15-60 minutes.


If you prefer to have your massage chair assembled for you, a White Glove Delivery upgrade is offered for this massage chair. If this option is selected, a professional installation team will schedule an appointment with you to determine the best time to deliver your massage chair. Once the delivery team arrives, they will carry the chair into your home or business, remove the packaging, and install it in the room of your choice. Your chair will be operating correctly before they leave.


If you prefer to have your massage chair brought inside your home or residence, a Threshold Delivery upgrade is offered for this massage chair. Your massage chair will be brought just beyond the main entrance of your residence or business, but not to a specific room. It can also be stored in your garage. This shipping method does not include assembly nor the removal of packaging. Threshold Delivery is a happy medium between free Curbside Delivery and White Glove Delivery.

This is fulfilled with Threshold Delivery.
