"Training device for Pelvic floor muscles" as MD in Japan has been established

Have you ever heard the word, "Train the pelvic floor muscles"?
The muscles span the bottom of the pelvis, Many women, especially those who have had childbirth or abdominal surgery, suffer from stress urinary incontinence due to the muscles not working normally (References 1).
To remedy the problem, training of the pelvic floor muscles, such as Kegel exercises, has been proposed (References 2).

Kegel exercises usually do not require tools. However, if you look at the Internet, you can see that there are methods using tools such as tools that give electrical stimulation such as EMS from outside the body or insert it into the vagina to enhance the training effect.

Notifications that place "Training device for pelvic floor muscles" as MD

While femtech is spreading in Japan, various pelvic floor muscle training tools are coming to Japan from overseas.
However, two recent notifications issued by the Ministry of Health, Labor and Welfare (MHLW) may change the market for pelvic floor muscle training tools in Japan.

These are the URL of the notifications, but I'm sorry, they're only in Japanese.

These two notifications have organized training tools for pelvic floor muscles. I made a figure.

From our slides document

Below this, I will briefly touch on the content of the notifications.
Please understand that the details may change as the official English translation of the MHLW is not yet available at this time.

First Notification

The first notification indicates that the "pelvic floor muscle training device" as defined below has been added as class 1 medical device .

It is a device for training the pelvic floor muscles at home by inserting it into the vagina for the purpose of improving urine leakage. However, those that give energy such as low frequency and electrical stimulation are excluded. Some are equipped with pressure sensors and programs that display training content.


Second Notification

The second notice outlines the medical device applicability of the training tools for pelvic floor muscles.
This notice states that "medical device-like purpose or effect" is "diagnosing, treating or preventing a disease or affecting the structure or function of the body".

It also gives an example of "a product advertised with this words is considered a medical device".

Anything that has a medical device-like purpose or effect, such as advertising or labeling the following medical device-like purpose or effect, falls under the category of medical device. (Omitted)

Impact on businesses

In the example above, you can see that there are a lot of words that you would want to advertise if you sell training tools for pelvic floor muscle.
However, the training tools for pelvic floor muscles advertised above are considered medical devices, whether invasive / non-invasive or prescription / home use.

If it is a medical device, the seller must go through pre-sales procedures and distribute it as a medical device.
Products that neglect to do so are unapproved medical devices, and the act of distributing them in Japan violates the PMD-Act and may result in arrest.

In recent years, in Japan, major EC malls such as Amazon.co.jp and Rakuten.co.jp have strictly demanded legal compliance with their products.
Also, although it is not a medical device, Amazon clearly states in Examples of Prohibited Listings "Cannabidiol (CBD) products that THC contamination has been discovered in the past (including products of the same brand and series)" for CBD products (References 3).
From these facts, it is expected that even a single administrative sanction will have a significant impact on the business.
Please understand the law and steer when selling healthcare products in Japan.
