I’ve come across many companies in the industry claiming to deliver Japan-made massage chairs despite them being manufactured in China. Osaki is one such company.
While I have no qualms with Chinese manufacturers, I find it hard to put my faith in any company that misleads its customers.
That aside, I’ve taken a look at one of their massage chairs — the OS-4000CS, to see if the company is worth its salt.
Truth be told, this massage chair offers some pretty decent features. The price on it isn’t ridiculous, to say the least. However, if you’re looking for a more practical purchase, the Kahuna SM3700 offers the same features and more for nearly half of its price.
Take a look at my in-depth review and comparison of both models below:
About The Osaki/Titan Company
If you’re looking for a company that is 100% Japanese made (i.e made in Japan and sourced from Japan) you’re out of luck. The Osaki company may have a Japanese-derived name, but most of its flagship products are manufactured in China.
Additionally, 90% of its products are manufactured in China as well. Normally, this wouldn’t be a big issue. Some China-made chairs and products are worth the money.
The problems stem from misleading consumers into thinking their products are manufactured in Japan. This growing trend has become increasingly problematic in recent years.
USA Based – This “Japanese” company is actually based in the United States. While that may actually be beneficial, it’s unclear as to why consumers would trust a company that blatantly misleads them.
100% Japan Made – Don’t get me wrong. There are some models of spring loaded that are manufactured in Japan. This is thanks to Titan’s work with Fujiiryoki, which is a leading manufacturer based in Japan.
Summary: Overall, I’d say that if you’re looking for a 100% Japan made chair, the Osaki company only carries very few. Aside from that, the company isn’t really Japanese at all. It’s US-based. On that note, if you were to invest in a US-based company, you’re better off spending your money in Kahuna chairs.
Osaki OS-4000CS Review (Notable Features & Benefits)
You could say that the OS-4000CS is one of the cheapest massage chairs with an L-Track system. Sitting at nearly $4000, this chair is considered among the lower middle class of chairs.
However, that doesn’t mean its functions are inferior. In fact, it actually packs some decent features. Take a look:
Zero Gravity Recline – You’ll reap the benefits of resting in a zero-gravity environment. Experts say that the virtually weightless state of relaxing a zero-gravity recliner offers will help your body recover faster from daily stress.
Here are some of the benefits of Zero-G:
- Ease back pain almost immediately.
- Reduces swelling and minimizes stress on your heart.
- Increases and stimulates blood circulation.
L-Track Massage – You’ll enjoy the attention your body gets from the L-track rollers on this massage chair. It targets your back, thighs, and glutes effectively for the ultimate therapeutic session.
- Compared to its predecessor—the S-Track massage system, L-Track massages are considerably superior. You may not know it, but your thighs and glutes work incredibly hard throughout the day. Every part of your body deserves attention.
Space Efficient Design – If you’re planning to put your massage chair in a smaller room, or are afraid of cluttering any room, the space saving technology of recline track design on this model is perfect for you.
- Unlike other recliner chairs, this model only needs 4″ wall clearance. It will slide forward before reclining, so you don’t have to worry about wasting space between your recliner and your wall.
Air Compression – If you’re either not a fan of intense massages or you want something more soothing on top of your therapeutic massage, you’ll enjoy the airbag massage system on this recliner.
- It effectively targets your whole body. That includes your lumbar area, waist, shoulders, feet, legs, and hands. It provides a completely immersive massage session when coupled with the advanced roller system.
Shoulder Adjustment – It has received multiple complaints from broad-shouldered customers in the past; luckily, the company listened. They have developed shoulder adjustments to accommodate customers with wider shoulders.
- The adjustability adds to the overall customizability. This will allow for a more custom-tailored experience. So whether you have broad or narrow shoulders, It will fit you comfortably.
Summary: The OS-4000CS carries many great features for the price. Some of the features you’ll find are more commonplace in higher-end units like the zero gravity position function. Overall, it is a great choice and a decent model. However, the Kahuna SM7300 is a more sensible option. Considering it’s features it’s a relatively cheap massage chair.

Reliability and Warranty of OS-4000
This top brand offers three warranty options. All of which are reasonable enough. Take a look at the different types below:
- Three Year Rock Solid Warranty – this warranty covers replacement and repairs without any charges for faulty/defective parts, workmanship or structure.
- First-year – Parts, Labor, Structural Framework
- Second Year – Parts and Structural Framework
- Third Year – Structural Framework
- Four Year Extended Warranty – if you want an additional year on your warranty, you can purchase it. By purchasing this added warranty, you are signing yourself up for an extra year of in-home service parts replacement and labor, and framework.
- Five Year Extended Warranty – if you really want to be sure, the five years extended warranty is basically the same as the four-year warranty. The only difference, of course, being that two years will be added to your standard warranty.
Additionally, you also have the option to have your massage chair delivered in-home instead of the standard free curbside delivery. Unfortunately, that will cost you an additional $99.
Moreover, if you want the white-glove service, it’s also unreasonably priced at nearly $180.
Summary: The warranty coverage is pretty decent. However, if you’re willing to spend the extra cash, get the extra warranty. There are also options for getting an in-home delivery instead of the standard curbside or white-glove service. However, those are very unreasonably priced considering it should come with your initial purchase.
Ogawa Robotic Massage Chair
This model is one of the few chairs that come with its own massage chair. This product is a special massage chair that can be attached to the chair’s base and can provide various types of massages. Other massage chairs come with an additional recliner for extended sessions but this one can work well with any kind. This Ogawa has a motorized mechanism that can tilt the chair back and forth. The chair has a massage function but if you don’t feel like getting up to use the massage function, you can just press the massage chair.
And it’s much easier than using an ordinary recliner. If you need the chair to work more than one way you can simply download the software from the company’s website. This is a unique piece of furniture because it can be used as an office chair but it also has the added benefit of providing massage sessions. The product itself is quite sturdy and it can hold all kinds of weight. The price is great considering that it also has a massage function and it is currently on sale. Pros: Very sturdy, More affordable than other products, Soft and cool like a large heated mattress, Comes with the chair itself. Cons: The device does not vibrate, Does not rotate or vibrate, A bit uncomfortable, and cannot raise up to lift up to the floor.
User Reviews, What Customers are Saying?
It’s easy to find great reviews on retailers like Amazon or MassageChairPlanet.
However, if you really want to know what you’re looking at from the company, you should head over to their Better Business Bureau profile.
Admittedly, there aren’t that many complaints. However, some of the complaints do attest to the poor customer service you will receive from this company.
You’ll find reviews about substandard massage recliners and poor craftsmanship as well.
But that isn’t to say you won’t find stellar reviews for some of their products.
Most reviews on online retailers average from four to five stars so they must be doing something right.
Note: It might not be the best idea to purchase a massage chair from a company that claims they are made in Japan when they are made in China. Additionally, the company itself is based in the USA. The only Japanese thing you’ll find on this company are 10% of its chair models and products and their name. However, they do deliver good products that are reasonably priced.
Questions & Answers
Where Are Osaki Chair Models are Made?
95% of their models are made in China. Only very few are actually made in Japan. Unfortunately, the unit I’m discussing in this article is made in China.
Can I Use a Massage Chair Every Day?
It is not advisable to use your massage chair’s massage feature every day. According to Titan Chair, overusing your massage chair is harmful to your body. As is with everything, it is important to use your massage chair responsibly.
Here are a few things to remember:
- It is generally more beneficial to use your chair for short 2-15 minute intervals.
- For a full body massage session, keep your use to 3-4 times each week.
- For stress relief and relaxation, it is recommended to use it 1-3 times each week.
You may think this is a ridiculous notion. After all, how can your completely relaxing massage recliner hurt you?
Subjecting your body to excessive massages poses a threat to muscle recovery.
Despite the benefits of regular massages, it’s not a good idea to subject your muscles to constant kneading.
It can have adverse effects on your health and could even worsen the pain you feel.
However, if you’re using your massage chair simply for its zero-gravity recline, body stretching features, or heat therapy, it’s perfectly reasonable to do so each day as long as you feel comfortable.
Are Osaki Massage Chairs Good?
Osaki chairs are good. However, if you’re spending money on a non-authentic Japan recliner, you’re better off purchasing a Kahuna. They’re usually less expensive and execute the functions more efficiently.
Is it Bad to Sit in a Massage Chair for a Long Time?
If your goal is to strengthen your hips, your glutes, and your hamstrings, then it is a very bad idea to sit in a massage chair for very long. By the way, this is also a bad idea to stand behind the massage chair and pretend that you are using it. I know, it is tempting to try and get that nice warm towel massage before getting your body into that torture chair.
However, you will inevitably need to sit in the massage chair for an extended period of time and your posture will worsen in the process. Think about it – sitting on a massage chair is like sitting behind a massage table for a 20-30 minute scalp massage. That’s right, in the process of getting your head massaged, you may have lifted and tightened your shoulders, hips, and even hamstrings.
If you came here looking for a Japan-made massage chair, I hate to burst your bubble. The 4000CS is unfortunately made in China. That said, China-made chair products aren’t necessarily bad. The Osaki is pretty decent.
Yes, some have reported structural problems. But there are also those who have openly recommended their purchase.
From what I see, the Osaki OS-4000CS is a good massage chair. It has a lot of great functions and is priced reasonably. However, the Kahuna SM7300 offers nearly the same features (and executes them better) for nearly half the price.
Summary: Kahuna is a more reliable company compared to Osaki. Their SM7300 unit is also less expensive than the OS-4000cs and performs the same functions more effectively.
