What Is The Osaki 4D Pro JP Premium?
The 4D Pro JP Premium is a high end massage chair from Osaki that is fully designed, engineered, and manufactured in Japan. Who is it made by? Fuji Medical. The same guys who’ve been in the massage game since 1954. In fact a lot of early technology and innovation in the massage chair industry came from Fuji, believe it or not!
In terms of intensity, 0 being mild, and 10 being crazy intense, this chair can do anything from a 6-10.
As far as intensity range is concerned, this is the best I’ve ever seen in an Osaki chair. It does a great job massaging at low intensities, and does just as well at high, deep tissue levels.
7 Key Features You Should Know About!
#1 Designed, Engineered, & Manufactured In Japan
As mentioned earlier, the Osaki 4D Pro JP Premium is 100% made in Japan. The company that makes this chair (Fujiiryoki) is an experienced manufacturer and really the “grandfather” of massage chairs. They started the whole shabang!
Did you know that most massage chairs sold today are manufactured in China?
Yes it surprised me too. In fact, majority of Osaki’s lineup is made in China. You may be wondering “what’s the fuss about? does it make a difference where a chair is designed and made?” And the answer is yes it does!
Massage chairs made in Japan are far superior to chairs made in China.
Japanese chairs are better designed in terms of function, and use high quality parts that last forever. If you’ve ever used a Japanese chair, you’ll kinda get what I mean. The entire system of airbags and rollers work perfectly in unison, and it feels like everything is awesomely synchronized!
Chinese chairs are more likely to malfunction or become defective over the years. It’s a similar analogy to cars. We all know how reliable Japanese cars like Toyota and Honda are!
#2 4D Roller System
We talked about 3D rollers the other day, and now we’re already up to 4D! This chair features what Osaki calls Kiwami Mecha 4D ball system. Quite the mouthful!
What are 4D rollers?
To really understand 4D rollers, you first need to understand 3D and 2D rollers. Let’s look at each in more detail.
The 4D rollers in this chair can protrude/extend about 4 inches out. It’s pretty insane considering most chairs can only extend out to about 3 inches!
Wait, I don’t get it….can’t 3D rollers do the same thing?
Yes and no. You can definitely adjust speed on a 3D roller chair. The difference with 4D is that the rollers are more “intelligent” so to speak. They’re programmed to massage at various speeds without you having to manually make the change. The objective is to try and replicate the movements of a massage therapist.
At this point, it’s important to remember why we even have massage chairs to begin with:
The sole purpose of a massage chair is to provide an automated solution to best replicate the real thing!
And if you think about it, that’s exactly what technologies like 3D & 4D are striving to do. Is there a marketing side to it? Absolutely 100% there is, but it’s also game changing technology at the same time!
#3 44 Airbags
The Osaki 4D Pro JP Premium has a total of 44 airbags all placed in areas where the 4D rollers cannot reach. These include the feet, shoulders, hips, glutes, calves, and arms.
Airbags can be adjusted to 3 different intensities, and what’s nice about this is you have the ability to alter intensity for 3 different regions: upper body, lower body, and footrest. For example, if I want to get the airbags to really work my shoulders, I can leave that as a high intensity setting without affecting the lower body and foot rest intensity.
For those of you who don’t know, airbags are just pouches that inflate with compressed air. When inflated, airbags provide an air compression massage to adjacent muscle and tissue.
Airbags also have a secondary function, and that is to maneuver and stretch muscles. Inflated airbags push out or hold onto specific muscles thereby inducing a stretch position.
#4 Heated Foot Soles
The Osaki 4D Pro JP Premium has a heating element on each foot pad. These provide a source of heat to the soles as they undergo an air compression massage.
One thing this chair doesn’t have are foot rollers. Foot rollers are simply rotating bars that provide a kneading massage to the soles. Instead this chair uses air compression over the entire foot.
If you’ve read my other massage chair reviews, you’ll know I’m a stickler for foot rollers. I think they make a massive difference as far as foot massage is concerned. It’s not enough to have air compression on the feet, there needs to be a good balance of different techniques, and a foot roller definitely helps with this.
#5 10 Auto Programs
I love auto programs. They’re quick, easy, and require no prior setup. Just push a button, sit back and relax!
This chair has a total of 10 auto programs. 5 of these programs belong to the “basic” category, and the other 5 are grouped in the “Kiwami Mecha” category. What’s the difference between both categories?
The 5 basic programs are all low intensity. The 5 Kiwami Mecha modes employ the 4D rollers, so massage intensity is greater.
As you can see from the list above, there really are 5 modes with each one having a slight variation or twist to it. If you’re looking for deep tissue intensity, you’ll definitely wanna try the Kiwami modes!
#6 29 Massage Techniques
This is what really distinguishes the Osaki 4D Pro JP Premium from other chairs. Non 4D chairs can only do about 6 different massage techniques. In fact, 6 is the max I’ve seen (4 or 5 is more common).
What are these 29 different massage techniques?
Before we get into what each of the 29 techniques are, it’s important to understand how these 29 techniques are categorized. There are 5 main categories:
- Basic—Consist of basic kneading, tapping, and rolling strokes.
- Mode—A combination of basic strokes.
- Shoulder—Various techniques focused on the shoulder area.
- Waist—Various techniques focused on the waist area.
- Section—Back massage on whole or part of the back.
It’s a little confusing to understand at first, but it should all make sense when you look at the table below. One of the descriptions for waist is missing just so you know. But there are 29 techniques. I counted them all!
If you want to know more about manual mode and how it works, then your best bet is to refer to the user manual. You can check that out by clicking here!
#7 120-170 Degree Recline
This chair can be positioned anywhere from 120-170 degrees. This can be done right from the remote control.
Does this mean it can recline to zero gravity?
No, zero gravity is more than just a recline angle. Zero gravity is when your legs are elevated above your heart, and your torso to leg forms an angle of about 128 degrees.
Important not to confuse recline ability with zero gravity. Both are 2 very different positions!
An Important Note About Japanese Chairs!
By now you may have realized how dumbed down Japanese chairs really are. What I mean is they don’t have all the bells and whistles you’d see in other chairs. For example, the Osaki Japan Premium 4D massage chair doesn’t have the following:
- No Zero Gravity
- No Foot Rollers
- No MP3 Speakers
- No Chromotherapy Lights
- Not For Larger Body Types
Important to understand these distinctions as you decide what to get.

Here’s What I Think About It!
What I Like (AKA Pros)
What I Dislike (AKA Cons)
Who Should Buy This Chair?
With all the different technologies, picking a massage chair can get really confusing. That being said, the Osaki 4D Pro JP Premium is not for everyone. Here’s who I think should consider this chair:
- If You Don’t Care About Zero Gravity & Foot Rollers
- If You Don’t Care About MP3 Speakers Or Chromotherapy Lighting
- If You Have A Small Body Frame
- If Deep Tissue Intensity Is A Must!
- If You’re Okay With A 27” Roller Track
#1 If You Don’t Care About Zero Gravity & Foot Rollers
As mentioned earlier, this chair does not have zero gravity recline capabilities. Also, it doesn’t come with foot rollers. If you don’t care too much about these, then you should definitely consider this chair!
My personal take is that both zero gravity and foot rollers are incredibly important, and I’m not sure if I could do without them!
However, you and I are not the same. Everyone has their own preferences at the end of the day!
#2 If You Don’t Care About MP3 Speakers Or Chromotherapy Lighting
MP3 speakers and LED lighting have no impact on my buying decision. To me it makes no difference if a chair came with these features or not.
It bears no effect on massage function whatsoever!
Osaki 4D Pro JP Premium doesn’t have speakers or LED lighting. Do you care? I don’t!
#3 If You Have A Small Body Frame
4D Pro JP Premium is not for large people. Important to remember that it was designed in Japan; a country where the average male height is 5’7 and the average female height is about 5’3.
If you’re over 6 feet, I strongly recommend against getting this chair!
However, if you have a small body frame and measure anywhere from 5’0-5’10, you should be fine.
#4 If Deep Tissue Intensity Is A Must!
If deep tissue intensity is a must have for you, there’s nothing quite better than the 4D Pro JP Premium. 4D rollers trump 3D rollers as far as massage intensity is concerned, and this isn’t just true for deep intensity, 4D can also give a much better mild intensity massage compared to 3D.
#5 If You’re Okay With A 27” Roller Track
As good as the 4D rollers are on this chair, they unfortunately have a restrictive 27” track span. What does that mean?
It means rollers can only target the neck and back.
If you’re looking for rollers that extend all the way down to the glutes and hamstrings, you need to consider an L-Track chair. The below 3 are fantastic options in my opinion.
However, there is a trade off. The 3 chairs above do have an extended track range, but they feature 2D rollers. Ultimately you’ll have to decide what’s more important to you:
4D rollers with a 27” track span, or 2D rollers with a 53” track span?
Best Place To Buy In The US?
Plenty of options if you buy online, limited choices if you buy in store.

Best Place To Buy Outside The US?
Always a little tricky if you live outside the US. Unfortunately massage chair deals do not ship to the US at this point in time, so your best bet is to either check locally in store or buy from Amazon.
You may want to check out your local Costco. From what I recall, they always seem to have a couple massage chairs kicking around.

Here’s how I’d summarize the Osaki Japan Premium 4D massage chair:
It’s a lot of good, and very little bad!
There’s a lot of great things about this chair, but the main highlight is the Japanese design and engineering. Everything from the 4D roller system to the airbags, down to the armrest is just so exquisitely put together. In my opinion, a full 10/10 as far as design and engineering is concerned!
As mentioned previously, the biggest shortcoming is the limited 27” track span. 31” would’ve been perfect for this chair. Also, Fuji & Osaki should’ve spent a little more time on user flexibility, specifically ensuring this chair fits a variety of heights.
I’ll end by saying this:
If you do decide to go for the Osaki 4D Pro JP Premium, you will not regret your decision!
