The Osaki OS-4D Pro JP Premium Massage Chair is one of the latest releases from Osaki, and is one of their few massage chairs designed and engineered in Japan. The OS-4D Pro JP Premium is manufactured by Fuji Medical (Fujiiryoki Japan), and is the same massage chair as their best selling EC-3900 model in Japan. Fuji Medical is the pioneer of the massage chair, and invented it back in 1954. The Osaki Japan model is equipped with Fuji’s patented Super Mechanism Technology, making the OS-4D Pro JP Premium one of the best massage chairs on the market today.
44 Airbags are placed through the OS-4D Pro JP Premium Massage Chair. Sit back and relax as the airbags inflate and compress on the arms/hands, calves and soles, buttocks and waist. The gripping and stretching action will squeeze and compress your muscles and body, slowly easing your pains and draining your stress and tension. This Japanese-made chair offers 5 automatic programs and 28 massage techniques that will focus on your legs, thighs and hips, waist, and back.
Product Description
QUICK PRODUCT OVERVIEW
- Made in Japan: A majority of massage chairs we carry are made in China, but the OS-4D Pro JP Premium is one of the rare massage chairs designed and built exclusively in Japan. Japanese chairs are known for being far superior than their Chinese counterparts as the material and parts used in the chairs are of significantly higher quality
- Manufactured by Fujiyroki: The OS-4D Pro JP Premium is not only of Japanese quality, but is made by Fujiyroki, the leading massage chair company in Japan. Their state-of-the-art massage chairs have never been introduced to the United States market prior to partnering with Osaki. This chair offers similar features and specs as many of their top models at a much lower price point
- Kiwami Mecha Basis 4D Knead Ball Roller System: The chair is equipped with a cutting-edge “4D” roller system very similar to the chairs that Fujiyroki produces that allows you to adjust the strength, width and speed of the rollers as it works the back. The rollers are unique in their ability to target notoriously hard-to-reach areas that many other massage chairs, including the shoulder blade, upper shoulder, back and neck unlike any other massage chair on the market. The “4D” rollers are capable of protruding an industry-leading 10 cm (about 4 inches) for a deep tissue massage
- 10 Auto Programs: Choose from 5 preset auto programs (Whole Body Rejuvenate, Shoulder Rejuvenate, Waist Rejuvenate, Whole Body Stretch & Whole Body Relax) and stronger versions of each of those same auto programs using the Kiwami Mecha mode
- 28 Customizable Massage Techniques: Dive into the chair’s manual programs to gain access to 28 massage techniques such as Knead Up/Down, Deep Knead Up/Down, Tapping, Shiatsu, Rubbing, Neck Relax, Extreme Kneading & Tapping, Rolling, Stretch, 3D Kneading & Tapping and more
- 44 “Air Magic” Airbag System: The chair’s innovative roller system provides a comprehensive massage that will not leave you wanting more throughout your back, neck and shoulders, but what massages the rest of the body? The 44 airbag system. 44 airbags are strategically placed throughout the chair to massage inside the seat (glutes and upper thighs), arms, outer shoulders, hips/waist, calves, the sides of your feet and the soles of your feet. Unique to the OS-4D Pro JP Premium is that you’re now able to independently adjust the strength of the airbags throughout three portions of the chair: the upper body, lower body and the footrest. Most massage chairs we carry only allow you choose from three settings to adjust all the airbags throughout the chair all at once without adjustments across the chair. With the OS-4D Pro JP Premium, for example, if your arms are sensitive, you can set a lower intensity in the upper portion of the chair while simultaneously enjoying a deeper airbag massage in the foot region
- Human-Like Massage: Experience a human-like massage that rivals a massage a professional massage therapist would offer from the comfort of your home or business
- 3D Point Navigation Body Scan: The OS-4D Pro JP Premium scans your entire body prior to your massage to customize it specifically for your body type and size. The chair’s technology allows the rollers to map the back curvature with more accuracy than ever before
- Heated Foot Massager: While the airbags work your feet and calves, you have the option of turning the heating pads on to receive a rejuvenating heated massage underneath the soles of your feet
- Adjust the Recline Angle of the Backrest and the Foot Ottoman: Independently recline the position of the backrest of the chair up to 170 degrees and the leg rest up to 147 degrees. The leg rest also has a spring that can be extended or retracted automatically for shorter or taller users
- Easy-to-Use Remote Control: The OS-4D Pro JP Premium is equipped with an easy-to-use LCD remote control. Choose any auto programs or any manual function with ease

DETAILED FUNCTIONS & FEATURES
Made in Japan
In a break from traditional massage chairs designed in China, Taiwan and Korea, the OS-4D JP Premium is manufactured and designed exclusively in Japan using far superior parts that will stand the test of time. While most massage chairs are manufactured in China and Taiwan, chairs made in Japan are known to be of significantly higher quality than their Chinese or even Taiwanese counterparts. The chair is made by Fujiiryoki, one of the leading massage chair companies in all of Japan. With the combination of Osaki’s excellent customer service in the United States and the true and tested quality of Fujiiryoki chairs, the OS-4D is now one of the most advanced massage chairs on the market today.
The new Kiwami Mecha Basis 4D Roller System
The OS-4D Pro JP Premium Massage Chair utilizes a 4D knead ball system that controls the speed and time of all 4D movements to replicate a similar, human-like massage a masseuse or therapist would offer. The ball system is capable of going up and down, side-to-side, in and out and to target areas that typical massage chairs simply aren’t able to reach with such precision, including a shoulder blade massage, an upper shoulder press massage and innovative side kneading.

Hien Tran –
After a long month of researching the massage chairs, I decided to buy the OS-4D JP. It’s exceptional and I am happy with the purchase.
Alex W. –
I bought the OSAKI OS-4D PRO JP PREMIUM sight unseen and it is an incredible machine. I’ve sat in a few chairs and we owned an old Panasonic years ago and this chair is a night and day difference. It will dig into areas of the body that no other chair I’ve sat in is capable of especially in the neck and upper shoulder area. If you’re looking for a serious massage chair, I’d recommend throwing down a few extra bucks for this Japan chair.
Wang Wei –
I was encouraged to review the Osaki OS-4D Japan massage chair so here it goes…
A little background —
I visited Japan nearly a year ago on a business trip and ran into the Fujiiryoki massage chair brand on several occasions and had a chance to really try out the EC-3800 a few times over the span of my one week trip and it was exceptional- truly beyond anything I ever imagined it would feel like. The massage chairs here in the states (and imported from China) pale in comparison.
Take it from me, I went to several Relax the Backs and Brookstone stores shortly after returning stateside and I was blown away by how inferior the near dozen chairs I tried were to the Fujiiryokis. Sure some were more than less than half the price of the Fujiiryoki chairs (but some close to the price of the OS-4D JP) so you would expect the quality of the chairs to be less than, but the difference was stark.
I wanted to buy a Fujiiryoki chair after my experience at the stores except for one problem- Fujiiryoki chairs are not sold in the US, so unless I wanted to spend a few thousand $$$s just shipping it from Japan to my humble home in New York on top of the ~$9,000 cost of the chair, it just wasn’t going to happen.
A few months back I found out that Osaki was teaming up with Fujiiryoki to bring their technology to the U.S. I did research before the purchase and found out that it’s the SAME chair as the Fujiiryoki EC-3900 rebranded under the Osaki umbrella for $3000-4000 less than if you were to buy the same chair in Japan. I bought it within a few hours of finding it a few months back without any reviews of the chair anywhere on the internet. I didn’t have to. The Fujiiryoki name was enough for me.
You will find another chair on the market that has better or similar features as the OS-4D JP (for cheaper), but if you’re serious about a true powerhouse that gives the most humanistic massage you’ve ever had from a massage chair, this is the one chair that will surpass your expectations. The rollers and airbags work your neck, shoulder, back, hips, feet, etc etc like you have a personal masseuse at your home. There is no other chair on the market that rivals this chair.
