What kind of device is Hyper Knife?
Hyper Knife is a professional body contouring (aesthetic) device for aesthetic salons developed and sold by Wamu Corporation. It features simultaneous 'warming' via 1 MHz high-frequency radio waves (bipolar method) and 'loosening' with a specialized handpiece.

What models are available in the Hyper Knife series?
Our current core models are Hyper Knife 7 and the flagship model Hyper Knife EX2. Hyper Knife 7 utilizes a 1 MHz bipolar method, while Hyper Knife EX2 allows switching among three frequencies (1 MHz, 1.5 MHz, and 2 MHz) and features both bipolar and monopolar methods. EX2 comes with a lifetime warranty.

Is Hyper Knife a type of HIFU?
No, they are completely different devices. Hyper Knife is not an abbreviation for HIFU. HIFU is a technique that focuses ultrasound on a single point, regarding which the Consumer Safety Investigation Commission (Japan) published a report in 2023 concerning accidents in aesthetic salons and similar venues. Hyper Knife is a device that warms and loosens using radiofrequency.
Is there a home-use version of Hyper Knife?
Hyper Knife does not have a home-use or personal model. It is a professional device designed for treatments performed by salon staff who have completed training. Items sold on the internet as 'home-use Hyper Knife' are not authentic products from our company. Note that the series does include a home-use EMS device called 'Hyper Wave Home.'
What is the difference between this and other radiofrequency devices like INDIBA?
For instance, while INDIBA uses a 448 kHz system with a return plate, Hyper Knife 7 operates on a 1 MHz bipolar method without a return plate, warming and loosening simultaneously (the flagship model EX2 also features three selectable frequencies and a monopolar method). It is better suited for targeted body contouring (aesthetic) and body sculpting menus rather than full-body thermal wellness care.

Yes, you can. In addition to initial adoption training, for individuals starting a business with no prior experience, we offer 'Independent Startup Support' covering a 10-day training program at directly managed salons, equipment introduction, and post-opening follow-up. Because this is not a franchise, you are free to decide your salon name and management policies.

Can staff who have not undergone training operate the device?
No. We believe Hyper Knife is equipment that should be operated by practitioners possessing accurate knowledge and technique, and we prohibit its use by untrained staff as well as self-aesthetic use where customers operate it themselves.

How do you distinguish genuine products from counterfeits?

Our company does not wholesale to e-commerce websites under any circumstances. For products purchased outside authorized dealers, quality cannot be guaranteed regardless of whether a serial number is present. Please note that repair services and overhaul support upon purchasing used Hyper Knife models 1 through 5 will terminate at the end of March 2027; after April 2027, official certificates cannot be issued and repairs will no longer be supported even for secondhand purchases.
