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. New in this model is the integration of a new sensor which offers a rubbing feature during the kneading modes. When combining the different modes this chair is capable of, a total of 85 unique massage techniques are possible.

There are four main manual massage functions: Basic, Mode, Part (1), and Part (2). Within those manual functions are several sub-menu massage techniques and regional massages.

• Basic: This button on the remote control will give you access to common massage techniques found in most chairs, including Kneading, Tapping, Rolling and Shiatsu/Wavelet
• Mode: This button on the remote control will give you access to advanced massage techniques only a Japan-made chair is capable of, including Loop Kneading, Loop Tapping, Loop Wavelet/Shiatsu, 3D Kneading, 3D Tapping, 3D Wavelet/Shiatsu, Stretch Kneading, Stretch Tapping and Stretch Wavelet/Shiatsu
• Part (1): This button on the remote control will give you access to regional massages targeting the Neck, Shoulder, Shoulder Blades, and Waist
