About our company

TOKYO IKEN CO., LTD. is a medical device manufacturer whose main products include the Superlizer infrared radiator intended for pain relief and healing of wounds.
The Superlizer is a phototherapeutic device that uses linearly polarized near infrared light to produce spot irradiation in the light wavelength band with the greatest living depth proficiency, and provides a high 2,200 mW level of power output.
The Superlizer has been adopted in all university hospitals in Japan and is highly appraised, with 20,000 units having been shipped in Japan and 5,000 units to a total of 12 other countries.
The Superlizer is available for both human and animal health care. In addition, we offer SonoCure?an ultrasonic surgical device-as a medical device for animals.

The Superlizer promotes improvement of blood flow through spot irradiation at a compound wavelength, providing light with the greatest living depth proficiency at a maximum output of 2,200 mW.
The Superlizer is not invasive or painful, but provides pleasant stimulation or a warming sensation, similar to that experienced with acupuncture or moxibustion.
Patients with drug allergies, elderly people, and patients with hemorrhagic or other diseases for whom nerve block is not suitable can undergo Superlizer treatment as an alternative adjuvant therapy to stellate ganglion block (SGB).
The device is easy to use, and is said to achieve almost the same level of effect as the injection of a local anesthetic (nerve block).
(Said to have 60% to 70% of the effect of nerve block.) Since advanced medical technology is not required, local irradiation can be performed by a nurse under the supervision of a doctor.

Stellate ganglion block and Light therapy

About Stellate ganglion block

The stellate ganglion is like an acupuncture point at which the sympathetic nerves controlling the head, face, neck, upper limbs, chest, heart, bronchi, lungs, etc. are gathered. Stellate ganglion block (SGB) therapy affects the hypothalamus, which is the center of the autonomic nervous system, and relieves systemic sympathetic tension.

Position of stellate ganglion
Stellate ganglion block (SGB)
Stellate ganglion light therapy (SGL) (Superlizer)

The Superlizer provides photoirradiation therapy, and is therefore largely free of the pain, invasion, side effects, and complications associated with conventional nerve block using a needle.
The Superlizer is effective as a non-invasive, safe adjunctive therapy for stellate ganglion block (SGB).
Note: The Superlizer is suitable for patients with drug allergies, elderly people, and patients with hemorrhagic or other diseases for whom nerve block is not suitable.

SUPERLIZER(For animal use) HP-5000A2 / LED Hyper

Superlizer Hyper5000A2

The Superlizer Hyper5000A2 is a phototherapeutic device which can perform spot irradiation at a high 5,000 mW level of power output in the near infrared (0.6 µm to 1.6 µm) wavelength band, which is the light range with the greatest living depth proficiency.
It results in a comfortable warm sensation unlike that created by conventional low power lasers, and provides comfortable, safe, painless treatment which is largely free of side effects and complications. The main body of the device has a space-saving compact design, and is also simple to operate. Currently, the Superlizer Hyper5000A2 is widely used for the treatment of cancer and other serious diseases, skeletal and skin conditions, and neurological disorders.
In particular, since cancer is the top cause of death in pets, its treatment is of great importance, and the Superlizer Hyper5000A2 is highly appraised in this field.

Superlizer 2200Lite

The Superlizer LED Hyper is a successor model of the Hyper5000A2. Light source is LED. It is a phototherapeutic device that can perform spot irradiation and wide range irradiation at a high 5,000 mW level of power output with linearly polarized light in the near infrared wavelength band (600nm~900nm).
Pad prove of new product can perform more wide range irradiation by Blue visible light (400nm~540nm) and Red visible light (800nm~900nm) and Near infrared (800nm~900nm) also can make 3 kinds mixing at a high 5,000mW level of power. which is the light range with the greatest living depth proficiency.
This device provides a comfortable warm sensation and has a strong therapeutic effect on various diseases, such as skeletal and skin conditions, and autonomic nervous and digestive system disorders. Since the device causes no pain, it is ideal for the treatment of delicate for the animals.

Tokyoiken company overview

Tokyoiken company overview

Since its founding in 1977 as a manufacturer of physical therapy devices, Tokyoiken has conducted pioneering research on the role of light in medicine. Tokyoiken has drawn on this research to create proprietary technologies capable of meeting rapidly changing needs in the medical industry.
These efforts yielded spectacular results with the introduction of our Superlizer device. Since the first unit was shipped in 1989, the Superlizer has earned a strong reputation among medical practitioners.

Today, as a manufacturer of physical therapy devices, Tokyoiken is meeting a wide range of medical needs, with a focus on delivering minimally invasive devices for treating pain.

Tokyoiken’s broad-ranging lineup includes Superlizer hototherapy devices and ultrasonic and interference therapy devices.
In the rapidly advancing field of veterinary care, where a high level of specialization and safety is required, practice has been evolving towards minimally invasive therapeutic techniues. Drawing on our expertise in this field gathered from human therapy, we developed our Superlizer veterinary devices and the SonoCure veterinary ultrasonic surgery device.



We aim to contribute to society through the development of medical devices specifically for pain.

Since its foundation, Tokyo Iken Co., Ltd. has launched a number of products related to pain centered on its mainstay infrared therapy device, Superlizer, and the company has fortunately received positive evaluations from everyone, allowing us to continue to present day. The target fields are expanding beyond humans to animals including pets, and the sales market is expanding not only in Japan, but also overseas.
In order to enjoy a better "wellness life" as society ages, it is necessary to control inseparable mental and physical "pain".
We will continue to conduct further research and provide even better products to make our small contribution to the development of medical care and society.
