Recommendations | Why Should You Buy This Chair?

With all the different technologies, choosing a massage chair can be very confusing. That said, the Osaki 4D Pro JP Premium is not for everyone. Who, in my opinion, should consider this chair:

  • If it’s ok with a 27″ roller track

As good as the 4D rollers on this chair are, they, unfortunately, have a restrictive 27-inch reach. What does that mean? This means that the rollers can only hit the neck and back.

  • If you have a small body

4D Pro JP Premium is not for adults. It is important to remember that it was designed in Japan; a country where the average height of men is 5’7 and the average height of women is around 5’3. If you are taller than 1.80m, I strongly advise you not to buy this chair. However, if you have a small frame and are between 5’0 and 5’10, you should be fine. You may consult our detailed discussions on ” Best Massage Chairs Buyers’ Guide 2022 “.

  • If you don’t mind weightlessness and rolling feet

As mentioned above, this chair does not have zero gravity recline capability. Also, it doesn’t come with foot rollers. If you don’t care too much about the latter, you should definitely consider this chair! My personal opinion is that weightlessness and foot rolls are extremely important, and I’m not sure I can live without them!

  • If you don’t mind the MP3 speakers or chromotherapy lighting

The MP3 speakers and LED lighting have no impact on my purchase decision. For me, it doesn’t matter if a chair comes with these features or not. This does not affect the massage function! The Osaki 4D Pro JP Premium does not have speakers or LED lighting. May l? I am not!

  • If deep tissue intensity is a must!

If deep tissue intensity is a must for you, it doesn’t get any better than the 4D Pro JP Premium. 4D rollers outperform 3D rollers when it comes to massage intensity, and this is not only true for deep intensity, 4D can also offer much better light intensity massage compared to 3D.


This is how I would sum up the Osaki Japan Premium 4D massage chair: It’s very good and very little harm!
There are many good things about this chair, but the highlight is the Japanese design and engineering. Everything from the 4D roller system to the airbags to the armrest is very well put together. In my opinion, a full 10/10 in design and engineering!

As mentioned above, the biggest flaw is the limited space of the 27-inch treadmill. 31 inches would have been perfect for this chair. Also, Fuji and Osaki should have spent a little more time on user flexibility, specifically making sure this chair accommodates a variety of heights.

I end by saying this: If you decide to opt for the Osaki 4D Pro JP Premium, you will not regret your decision!
