Since their inception/popularization, one of the best ways to practice listening has always been audiobooks. However, due to the ridiculous prices/one coin per month model of Amazon, this resource was a bit beyond what most people would consider good value.
However, as of now, Audible Japan has switched to a 聴き放題 model, bringing it in line with many other countries. This means you can listen to as many books as you want for a flat monthly fee (about ¥1800).
This is incredible value for the amount of material that is included in a very very wide range of categories. Light novels, biographies, world history, politics, self help, business and economics, communication, just to name a few.
I would not have recommended audible before today, but 100% recommend it in its new structure. You are also able to download books for offline listening as is standard with many other streaming sources. The only downside at all is that not 100% of books are included in the ‘all you can listen’ model, and must still be purchased. However, this is mostly new releases/business books.
Last note - As audiobooks follow the books themselves 100% (in most cases), they are also great to follow along with while reading.
Hope some of you guys are able to make use of this! I sure will be
