    Double Sensing Body Scan

    The Japan Premium 4S Japan Massage Chair is equipped with a dual auto detection body scan that optimizes the roller to detect your acupoints along your back and even optimize the depth of the massage.  This will enable you to get the most customized massage possible as the computer will map the length of your spine and width of your shoulders.

  • Osaki 4D difference - 12 strength adjustments

    12 Strength Adjustments

    There are 12 levels of strength adjustment in the Osaki Japan Premium 4s to really fine tune the applied strength of the massage rollers. Most massage chairs have 3-5 levels of adjustments, and having 12 makes the Premium 4S even more versatile.

  • Osaki Japan Premium 4S Massage Chair - Infrared Heat Therapy

    Heat Therapy

    Located in the feet area and lumbar area are infrared heating pads that warm up your muscles and joints. As the muscles warm up, the tissue will loosen up and allow the massage chair to provide you with a better, more therapeutic massage. Note: you will not feel the heat as prevalently as you would with normal heating elements however you will get even more healing benefits at a cellular level with the Infrared featured in the 4s.

  • Osaki Japan Premium 4S Massage Chair - Foot AcuNote + Foot & Calf Air Compression

    Leg, Calf & Feet Massage

    The airbags will inflate and deflate both the side and back of the calves to stimulate the Zu San Ri acupoint. This has been known to boost your immune system and even your overall energy levels. The airbags also press your feet into the acupressure nodes at the bottom of the soles that will help alleviate fatigue and tension.

  • Osaki Japan Premium 4S Massage Chair - next generation air compression

    Osaki Japan Premium 4S Air Compression

    There are 34 airbags that provide a thorough and full body compression massage targeting your feet and legs, hands and arms, shoulders, and waist and pelvis. The soothing air massage combined with the massage roller offers a full body massage to work out any tension and stress that you may have. The Triple Mode Air System will provide therapeutic relief for sore muscles and promote blood circulation. This flow rate adjustment comes with 3 modes to tailor your massage to your needs: Knead, Pulse, and Normal.

    Osaki has re-engineered its air massage technology, reducing the total airbags but increasing the surface area coverage. This reduces the stress on the air pump and valves, ultimately extends the longevity and dependability of this component.

    • Outer Shoulder Massager:  located on the upper sides of the backrest, there are 2 airbag massagers on each side. As the air bags inflate it will compress the shoulder inwards. The shoulder airbags may also inflate to hold you in place as the back rollers apply a soothing massage.
    • Hand & Arm Massager:  As you insert your arms into the unique butterfly design, it will position the palm of the hands vertically. Simultaneously the hands and forearms will be massaged as the air bag inflates. The tapered design will contour the arms for an even massage.
    • Hip Massage:   Along the sides of the seat base are airbags on each side. As they inflate it will squeeze the hips.
    • Foot & Calf Massage:  The calve massage is curved on the outer walls so that it will wrap around the calves as it inflates. There are also airbags on the back of the calves for a more complete massage.  The feet are massaged by airbags which are lined the along the sides, pressing the feet down to the base of the foot massager.

    New Dimensional Kneading Technique

    Kneading technique is the heart of the massage chair. Kneading in Osaki Japan Premium 4.0 relies on a new sensor which optimizes the rubbing by further implementing the new dimensional massage.

Wish RockAll of our items have a FREE SHIPPING OPTION

We strive to ship your items as fast as humanly possible--and try to regularly beat our goal of 5 business days from your order date.  We will send you tracking information within 24 hours of your order leaving the warehouse to the e-mail address you provided when checking out.  If you do not receive tracking information from us within six business days of your order, feel free to follow up with us at hello@wishrockrelaxation.com.

All orders cancelled after 48 hours are subject to a $20 administration fee, if your order has not shipped. If you order has shipped, you (the buyer) will also be responsible for actual return shipping charges as well as a 15% restocking fee. Refunds will only be issued to the original credit card that you used when placing your order. 

  • If you choose our free shipping option, you can expect to receive your item curbside within 7-10 business days of your item shipping--oftentimes sooner.  If you do decide to go with curbside delivery, expect to have help with moving the chair into your home and desired location as many of our chairs are quite heavy.
  • If you choose white glove delivery, there will be an additional charge of $250. Your item will be delivered to your home, placed in the room of your choice exactly where you want it and set up.  Because we have to use an outside contractor for this service, your delivery time will be extended by one week.  Also, if you have a difficult location (several stairs with challenging turns etc) please send us pictures so that we can make sure the delivery company is prepared. If they arrive and it requires a 3rd man, there'll be extra charges such as an extra return trip and fee--we don't want you (or us) to have any surprises.  Please really think about if you need white glove delivery--it's a lot more challenging and expensive to add it after your order has been placed.

We will do everything possible to ensure that your item arrives in the same condition that it left the manufacturer. Any product damage or loss is the responsibility of the shipping company, not Wish Rock Relaxation.

BEFORE you sign the shipping weigh bill, please THOROUGHLY INSPECT YOUR ITEM.Signing for receipt of a damaged product removes the liability of the shipping company and Wish Rock Relaxation. Once you accept your shipment as non-damaged, the item is yours.

If for some reason you have decided to return your item, it will need to be boxed back up and placed onto the pallet for pickup.  We offer free returns within 30 days, however you are responsible for the return shipping costs (which will include outbound shipping where applicable) and any restocking fees from the supplier (15% from those that charge it - HT) unless you exchange your item for an equal or more expensive item.  We will work with you to help you get into the right chair for you and will do our best to mitigate the fees wherever possible.
