4D Massage Rollers: With 4D rollers, users have the power to control not just the depth and direction of the massage, but also how intense and vigorous the massage feels. This level of customization is invaluable, as it allows individuals to tailor their massages according to their preferences, physical condition, and desired relaxation level. Whether you're seeking a gentle, soothing massage after a long day or a more invigorating deep tissue treatment to work out muscle knots and tension, 4D rollers can accommodate your needs. The Maestro 2.0 features heated massage rollers, the Kaze does not. 

SL-Track System: The effectiveness of the SL-Track system lies not only in its comprehensive coverage but also in its ability to follow the natural curvature of the spine. This means that as the massage rollers move along the track, they can closely mimic the motions of a skilled human masseuse, delivering a more authentic and therapeutic massage experience. The combination of the S-Track's attention to upper back and neck muscles with the L-Track's focus on the lower body results in a harmonious synergy that addresses a wider range of muscle groups and tension points. The Maestro 2.0 has a track length of 52.8” and the KaZe has a track length of 44”.

Full Body Air Massage: Full body air massage is a revolutionary feature in modern massage chairs that takes relaxation and therapeutic relief to new heights. Unlike traditional massage techniques that primarily rely on mechanical rollers, the full body air massage employs a network of strategically placed airbags to provide a unique and enveloping massage experience. This technology capitalizes on the soothing power of air compression to gently and effectively alleviate muscle tension, improve blood circulation, and promote overall well-being. The concept behind full body air massage revolves around the use of airbags that inflate and deflate rhythmically, creating a gentle squeezing and releasing sensation on various parts of the body.

Body Pain Scan: The body pain scan is a revolutionary feature in modern massage chairs that redefines the way we experience personalized relaxation and therapeutic relief. It represents a remarkable integration of technology and wellness, offering users a tailored massage experience that addresses their unique areas of discomfort and tension. At the core of the body pain scan is an advanced sensor system that is strategically placed within the massage chair. This sensor system is designed to accurately map the contours of the user's body, identifying areas of muscle tightness, knots, and tension. By employing infrared technology and sophisticated algorithms, the body pain scan system creates a virtual map of the user's body, highlighting specific regions that may require attention.

Body Scan Technology: The process of body scanning typically begins as soon as a user sits in the massage chair and initiates the scan. The sensors delicately and swiftly assess the user's body, creating a digital map that outlines the individual's unique dimensions and contours. This map serves as the foundation for delivering a massage experience that is tailored to the user's specific requirements.

Deep Calf Kneading: The calf muscles are a crucial part of the lower body, playing a significant role in mobility, stability, and overall comfort. However, due to factors such as extended periods of sitting, standing, or strenuous physical activity, the calf muscles can become tense, knotted, and fatigued. Deep calf kneading addresses these issues by employing a combination of advanced technology and expert technique to provide a thorough and effective massage to this vital muscle group.

Foot Rollers & Foot Kneading: Foot rollers and foot kneading are designed to replicate the therapeutic actions of a skilled masseuse's hands on the feet. These techniques recognize the significance of the feet in our overall comfort and relaxation, as they encompass numerous pressure points and reflex zones that are linked to various parts of the body.

Spot Massage: Spot massage allows users to designate a particular area of their body for intensive attention. This is typically done by manually selecting a specific point on the massage chair's control panel or through the chair's accompanying remote control. Once the spot massage mode is activated, the massage chair's rollers or airbags concentrate their efforts solely on the chosen area, delivering a deep and targeted massage experience.

Space Saving Technology: Enter space-saving technology, which ingeniously addresses this limitation by reimagining the mechanics of how massage chairs recline. Instead of moving the entire chair backward as it reclines, space-saving massage chairs are designed to slide forward first before reclining. This forward-sliding motion minimizes the amount of space needed behind the chair, making it possible to place the massage chair closer to walls or other pieces of furniture. Both the Maestro 2.0 and KaZe only require 5 inches of clearance away from the wall. 

Voice Control: With voice control, the process of adjusting massage settings, selecting programs, and customizing your relaxation experience is simplified to a few spoken words. This technology recognizes natural language commands, enabling users to communicate with the massage chair in a way that feels natural and user-friendly.

Wireless Charger: Wireless charging eliminates the need for tangled cords and outlets. With this technology, users can simply place their compatible smartphones or other devices on a designated charging pad embedded within the massage chair.

Bluetooth Speakers: By integrating Bluetooth speakers directly into the massage chair, users can effortlessly connect their smartphones or other Bluetooth-enabled devices. This connectivity enables them to play their preferred music playlists, audiobooks, or meditation sessions without the need for separate speakers or headphones. The audio emanates from the chair itself, enveloping the user in a cocoon of relaxation.

Touchscreen Controller: The touchscreen controller serves as a central hub where users can easily customize their massages to suit their preferences. Through intuitive menus and icons, users can choose from an array of massage techniques, adjust the intensity, target specific areas of the body, and even create personalized massage programs. The touchscreen's visual and interactive nature makes the process seamless and enjoyable, allowing users to effortlessly tailor their massage sessions to their unique needs.

Shortcut Panel: The convenience of the shortcut panel lies in its simplicity and ease of use. Instead of manually configuring each aspect of the massage experience, users can select a desired massage technique, area of focus, or program with a single touch. This allows for quick adjustments when transitioning between different massage sessions or when changing preferences on the fly.


Automatic Massage Programs: Automatic massage programs represent a pinnacle of convenience and sophistication in the realm of massage chairs. These programs encapsulate the expertise of professional massage therapists, offering users a curated and comprehensive massage experience that caters to various needs, preferences, and wellness goals. Designed to simulate a diverse range of massage techniques, automatic massage programs eliminate the need for users to manually adjust settings or select individual massage techniques. Instead, users can choose from a selection of pre-programmed options, each specifically crafted to address different aspects of relaxation and relief. The KaZe comes loaded with 10 automatic massage programs and the Maestro 2.0 comes with 15 automatic massage programs. 

Massage Techniques: Massage chairs are designed to replicate a variety of massage techniques, bringing the expertise of professional masseuses directly into your home. These techniques offer a diverse range of therapeutic benefits, catering to different needs, preferences, and wellness goals. Here are the massage techniques the KaZe and Maestro 2.0 use. 

JPMedics KaZe: Knead, Tap, Swedish, Clap, Shiatsu, and Rolling

Osaki 4D Maestro 2.0: Rolling, Kneading, Shiatsu, Tapping, Clapping 

Airbags: The airbags in massage chairs work through a system of controlled inflation and deflation. As air is pumped into these chambers, they gently expand, applying pressure to specific areas of the body. This pressure mimics the sensation of kneading, tapping, and compressing motions used in various massage techniques. When the airbags deflate, they release the pressure, allowing the muscles to relax and promoting improved blood circulation. The KaZe and Maestro 2.0 both come equipped with 30 airbags. 

Heat Therapy: Heat therapy is a therapeutic feature that enhances the massage chair experience by providing soothing warmth to targeted areas of the body. Integrating heat therapy into massage chairs elevates the relaxation and therapeutic benefits, creating a holistic and rejuvenating experience that goes beyond traditional massage techniques. The Maestro 2.0 does not feature any heat therapy other than the heated rollers. The KaZe features heating pads that target the lumbar, seat, and calves. 

Automatic Legrest Extension: The automatic legrest extension feature acknowledges the importance of proper leg and foot positioning during a massage. When the chair is activated, the legrest extends or retracts based on the user's height, ensuring that the legs are properly supported and that the feet are in an ideal position for the massage to take full effect. This ensures that pressure points are targeted accurately and that the massage rollers or airbags can work effectively on the calves and feet. The KaZe’s legrest must be manually adjusted.

Memory Programs: Memory programs essentially serve as a personalized massage playlist, where users can create, save, and recall their ideal massage sessions. This feature is particularly valuable for individuals who have specific preferences for massage techniques, intensity levels, and target areas. With memory programs, users can effortlessly recreate their favorite massage experiences without having to manually adjust the settings every time they use the chair. The Maestro 2.0 does not have this feature. 

Chromotherapy: Chromotherapy, also known as color therapy, is a unique and innovative feature that aims to enhance the relaxation experience in massage chairs. Rooted in the belief that colors can influence our emotions, mood, and overall well-being, chromotherapy in massage chairs involves the use of colored lights to create a harmonious and soothing ambiance during a massage session. The Maestro 2.0 does not have this feature.

Choosing between the JPMedics KaZe and the Osaki 4D Maestro LE 2.0 massage chairs ultimately comes down to your personal preferences, priorities, and wellness goals. Both chairs offer a range of advanced features designed to provide a luxurious and effective massage experience, but there are certain aspects that might make one chair more suitable for you than the other.

If you prioritize innovative technology and a customizable massage experience, the Osaki 4D Maestro LE 2.0 might be the chair for you.

The advanced features like space-saving technology, foot rollers, and body stretching further enhance its appeal, making it a great choice for those seeking a comprehensive and customizable massage experience.

On the other hand, if you value Japanese craftsmanship and a focus on holistic wellness, the JPMedics KaZe might be the chair that aligns with your preferences. The KaZe's medical-grade technology, SL-track system, and intuitive touchscreen controller emphasize relaxation, muscle relief, and overall well-being. The emphasis on deep tissue massage and the utilization of air cells for comprehensive body coverage can make this chair a great fit for individuals who seek effective muscle therapy and stress reduction.
