If you like サッカー there is a lot of content available for free. Even lowly clubs like [SC Sagamihara are putting out content like this](https://youtu.be/JUMRnkD9WtM?si=aa2d7X-uBQQkAeLo). You’ll notice that Japanese is fairly easy to understand, you can pick up a lot of vocabulary outside of the textbook speech and the speed and rhythm is normal.
Also, it’s subtitled in Japanese so if you don’t catch a word you can pause and look it up.
