NAG Orthopaedic Clinic
NAG Orthopaedic Clinic led by a sports medicine specialist, Yoshiaki Nagumo, MD, PhD.NAG Orthopaedic Clinic led by a sports medicine specialist, Yoshiaki Nagumo, MD, PhD, was established in 2023 in Shirokane, Tokyo.
Dr. Nagumo originally started his career as a bone and soft tissue tumor specialist. He is a surgeon who specializes in the treatment of musculoskeletal tumors. After several years of clinical activity, he moved to the US (The University of Iowa) in 2018 for a few years to research regenerative medicine. As a researcher, his main areas of research were cartilage regeneration with mesenchymal stem cells and tissue engineering with cell culture supernatant, also known as conditioned medium, which is one of his current clinical treatment tools.
Dr. Nagumo has been engaged in several sports: weight training, CrossFit, boxing, grappling, trekking, and freediving. In 2018 in the US, he accidentally injured his left knee, and the injury was diagnosed as meniscus tears. However, the sports medicine specialist who tended to him instructed him to just rest and neither offered any other treatment nor gave advice. This experience let him strongly feel the need for sports injury treatment specialists who put themselves in the patient’s shoes.
After coming back to Japan, he decided to change his specialty to sports medicine specialist and began support activities of several sports players and teams.
NAG Orthopaedic Clinic provides medical care to various patients who have orthopedic conditions, such as shoulder and elbow, hip, knee and lower extremities, and spinal disorders, based on precise diagnosis through physical examination and MRI as well as CT scan. In addition, there are several regenerative medicine-based intravenous drips that focus on healing treatment-resistant joint pain and fatigue.
NAG Orthopaedic Clinic also consists of a physiotherapy/massage room and training space where you can enjoy relaxation hand therapy and low-intensity training, including fixing pelvic tilts and body realignments with expert sports trainers.

NAG Orthopaedic Clinic & HealthyTOKYO
Dr. Nagumo highly recommends HealthyTOKYO CBD products and the company overall due to their exceptional quality, trustworthiness, and established reputation. The company’s CBD products are crafted from hemp stems and seeds that are organically grown in the United States. These raw materials are processed in HealthyTOKYO’s own factory in Tokyo, ensuring that every step from importation to manufacturing adheres to strict quality control measures. This rigorous process guarantees that all products comply with Japan’s legal requirements, resulting in superior CBD products that meet high standards of safety and efficacy.
Furthermore, HealthyTOKYO’s commitment to safety and transparency is evident in their thorough testing procedures. Each product undergoes two rounds of ingredient checks before being shipped, and the certificates of analysis for these checks are readily available on the company’s website. This level of transparency and dedication to safety is a hallmark of HealthyTOKYO, providing peace of mind to users, including athletes and children, who can trust that they are using a product that is both safe and consistent.
In addition to their high-quality and trustworthy products, HealthyTOKYO has established a strong presence in Japan. They have outlets in major department stores and have even opened the world’s first CBD shop in an airport at Haneda. This widespread availability and high visibility underscore the reliability and acceptance of HealthyTOKYO products. Their presence in such prominent locations further cements their reputation as a trusted provider of CBD products suitable for use even in medical settings.
Dr. Nagumo believes that these factors—quality, trust, and widespread acceptance—make HealthyTOKYO CBD products a reliable choice for consumers seeking safe and effective CBD solutions. The meticulous attention to quality, the rigorous safety and transparency measures, and the strong market presence all contribute to HealthyTOKYO’s standing as a leader in the CBD industry.

His Patient’s Experience with HealthyTOKYO’s CBD Products
Sprains
Sprains in the foot or fingers occur due to ligament damage around the joints, and CBD cream is a good treatment for such injuries. Immediately after the injury, anti-inflammatory drugs, braces, and taping are used for treatment. However, when some time has passed and there is no severe pain but still some discomfort, or in cases where the patient is allergic to oral medications or patches, using CBD cream can gradually relieve the pain in the affected area.
Iliotibial Band Syndrome
Iliotibial band syndrome is common among people with knee joint deformities or runners. The iliotibial band is a thick ligament on the outside of the knee joint that supports body weight on the outer thigh, often causing pain around the joint. For pain in such tissues, CBD oil is a good treatment option. Applying high-concentration CBD repeatedly can gradually improve the pain, allowing continued exercise.
Dr. Nagumo’s Personal Experience with HealthyTOKYO’s CBD Products
Popliteus or Back of the Knee Muscle
Due to cartilage damage in my left knee, I tend to experience pain in my left knee after running or weight training. The pain is particularly felt behind the knee, where inflammation occurs in the muscles supporting the knee from behind. Patches come off easily in this area, and the pain is not severe enough for oral medication. Therefore, I apply CBD oil about three times a day. There is no immediate change, but with repeated application, the dull ache behind my knee gradually eases. Thanks to this, I can continue training without taking breaks, combining treatment and maintenance.
Enhanced Focus During Work
I use sublingual CBD oil primarily during the day while working. It is especially effective when I need to create documents before and after consultations and want to maximize my focus within a limited time. Initially, I did not notice any change, but after repeated use, I found the right dosage for myself and could use it effectively.
FAQ: Ask Doctor Nagumo
What CBD do you recommend for sleep and why?
The CBDTokyo Night Gummy is a good choice as it contains several beneficial compounds found to be helpful with falling asleep and staying asleep. These include 26.1mg of CBD, kuwansou which is a flower extract from Okinawa, GABA- an amino acid, and Vitamin D. You can also use tinctures like HealthyTOKYO Yuzu or Mint 12%. In general, you should take between 25 and 50mg of CBD for sleep. Patient experience can vary, so start with the lower end of dosing and increase if you feel the need.
How much CBD cream do you need to treat a stiff shoulder?
You generally need about 5mg CBD for muscle pain. Some studies even need more amounts of CBD for muscles bigger than biceps. With HealhtyTOKYO CBD hand cream, you can use a small pearl-size drop that contains about 5mg broad spectrum CBD. You will feel pain/stiffness relief within 30 minutes. If not, apply two to three pearl-sized drops at a time. Frequent application such as every four hours is needed for topical usage.
Can you use CBD cream/oil for joint pain?
Yes, but I recommend you apply CBD cream/oil to the muscle around the joint instead of the joint surface itself and use CBD tincture to suppress joint pain. The amount of CBD for joint pain can vary, so start with the lower end of dosing and increase if you feel the need.
Does CBD topical usage have any mental effects?
CBD applied to the skin would be absorbed and brought into the bloodstream. But its amount is very little and usually doesn’t cause any mental effect.
Is CBD OK to give to children?
Yes, CBD usage among children is fine and there is no exact age limitation in Japan. The important thing is to identify why you want to give your child CBD. Is it for pain, for stress, anxiety, sleep, epilepsy etc. After defining the reasons, you must consider the proper dosages for their condition. Also, I personally don’t recommend you use vape for children worrying about the future risk of smoking and the unidentified physical risk of vaping for children.
Can you use CBD when pregnant?
Just to be on the safe side, I recommend that you do not use CBD orally when pregnant as there have not been a lot of studies done yet with CBD and pregnant women. The same goes for women breastfeeding. Topical CBD products can generally be used as the absorption into the bloodstream can be assumed to be modest.
