What is Mimikatsu? An easy study method to start for free

Mimikatsu refers to the activity of listening to audio, such as audiobooks and the radio, with your ears.
In fact, the number of people starting Mimikatsu is rapidly increasing.
When you are busy with daily work and housework, it is difficult to find time to read books or study, isn't it?
In such times, Mimikatsu—studying or relaxing your mind by listening to audio—is recommended.
Mimikatsu can be started easily and for free as long as you have a tool to listen to audio, such as a smartphone.
In the past, many people listened to the radio or podcasts, but with the advent of AI, it has become possible to listen to your favorite books by converting them into audio using free AI text-to-speech apps (AI text-to-speech services).
Because Mimikatsu only requires listening to audio, it's okay to do it while doing other things like walking, running, working, doing housework, or driving a car.
By listening to audio, you can study, calm your mind, and use your work or housework time to improve yourself.
That is what Mimikatsu is all about.
Why is Mimikatsu popular? Recommended for those who value time performance (Taipa)

Mimikatsu is popular because it can be done anytime, anywhere.

With Mimikatsu, which only uses your ears, you can use your time freely while doing other things like work or housework.
It is also perfect to do while walking or running.
Recently, the number of people who value time performance (Taipa), such as watching videos at double speed or taking side jobs during gap time, has been increasing.
