Japanese Comprehensible Input, How Many Hours of Content:
As a companion to my last post, this post is going to link a ton of comprehensible input lessons and other resources that can be used as comprehensible input, and how many hours of content it adds up to. I'd like to shout out r/ALGhub that has a list of Aural Resources for Japanese, and CIJapanese has a Resources Page of other materials besides their own lessons that can be used for getting comprehensible input in japanese. CIJapanese.com has more videos on their site for a paid subscription, and a free youtube channel with lessons, I've only counted the youtube lesson hours in this estimate. I appreciate the cijapanese.com website and teachers, and may pursue using their paid video lessons in the future.

Listed Resources on CIJapanese (Videos):
https://cijapanese.com/resources (I highly recommend this page for finding videos, audio, and reading materials)
Note that the resources list on the CIJapanese website lets you sort by level (Beginner, etc) so you may want to sort it by level then pick material to use.

Hours total of the CIJapanese website recommended video resources (excluding their own videos): 1,243.20 hours
Total of combined hours in this list: 1,430.20 hours
I would suggest that in addition to all of these video resources, you supplement using audio-only resources like the podcasts listed on https://cijapanese.com/resources, https://comprehensibleinputwiki.org/wiki/Main_Page#Japanese, and any other podcasts you can find and understand.
Other options to get more comprehensible input: children's cartoons if there's visual context clues, vlogs especially if they're vlogs about what they do in a day/the visuals directly relate to what's going on, audio books of graded reading materials you're reading (or TTS of the graded reading material if that's the only option available) - an app like Satori Reader with graded reading material and audio would work well, rewatching shows in japanese that you've seen before (japanese dubbed shows, anime in japanese dub, jdramas), replaying games in japanese that you've played before, watching let's plays of games you've played/seen before, new shows in japanese if your level of comprehension is enough to follow the main idea (shows where the visual context is related to what they're saying will be easier - such as romance shows, slice of life shows, some reality shows, cooking shows, action shows where they talk about what they're doing, crime solving shows where they talk about the objects in the scenes).
