I interpreted that comment as being in the past and that they had progressed past N4 now. But if that’s not accurate yet then, yeah my recommendation doesn’t stand right now.
I was taken aback how easy the Cardcaptor Sakura Anime was. I tried after that several other series like Digimon or Pretty Cure and non of them hat so easy and basic conversations.
I’m quite new to learning Japanese myself, but I can highly recommend an application called Yomininja. It uses OCR to scan your screen for text, then overlays little boxes above the text that reveal text you can scan using Yomitan. It’s very useful for quick lookups and word mining directly into Anki while playing Videogames or reading Manga.
As for games, I am currently playing ぼくのなつやすみ and I’m having a blast with it. It’s a very relaxing PSX game about a boy who is spending his summer vacation in the Japanese countryside.
I have been studying Japanese off-and-on for years, too. I felt very frustrated because I thought I wasn’t able to read native material yet. But after learning about 650 kanji I started searching for some materials and discovered I could read more than I could expect. I found all the information I needed in Reddit, Learn Natively and Game Gengo’s youtube channel. This has been my journey so far:
Manga: Chi’s Sweet Home (very easy), Yotsubato!, Flying Witch (up to volume 7 or 8; I dropped it because it gets more and more difficult, with long sentences and tons of magic words and stuff), Kimi no Na wa., Marmalade Boy, Shirokuma Cafe, Rental Oniichan. I recently read Mint na Bokura (from the same author of Marmalade Boy), Happiness (very easy but adult-themed and dark story), Neko Hajimemashita (a bit too much repetitive for my taste). Currently reading Barakamon and Love Hina. Tried One Punch Man and Ranma but found them too difficult for me.
Video games: After Animal Crossing (Switch), I started with Sumire (Steam), very easy. I didn’t finish it though because the story was not that interesting. After that I played Toem, a little gem which can be a bit challenging at times but I didn’t find it overwhelming at all. Then I played Another Code: Recollection (Switch): easy, with furigana, audio and you can replay the dialoges; loved both games (I had played the DS original). The first Famicom Detective Club game (Switch) was a very good choice, too (I still have to play the other two games, though). I highly recommend Toem, Another Code and Famicom Detective Club. I will play Shin-chan’s Me and the Professor on Summer Vacation this summer (hopefully!).
Anime: I started watching Ranma but dropped it. Same happened with Shirokuma Cafe, which is great for learners, but I’m not very interested in anime so I barely use anime as a learning tool.
Hope this helps!
In case anyone was interested, Shin Chan: Me and the Professor on Summer Vacation is 50% on Steam.
First, this is INCREADIBLY subjective. Any possible suggestions will be filtered through what each person found easy. Not necessarily what is easy.
Example: Someone who is into tennis and has learned all the tennis lingo is going to find tennis related content far easier than someone who has gone all-in on football content.
As such, the most important thing to take into consideration is what you have already learned. If you are still so early into your learning that you haven’t found a “domain” to learn in, pick one and try to either stay in it or near it. That way you are not having to constantly contend with new terminology specific to that one media source.
They bated me into watching some of it: https://www.youtube.com/watch?v=Gl2ck8I5spI&ab_channel=TheBellman
But for some reason, it’s a show for little girls but with extremely good fight scenes
(The Only Japanese Goblin I know is not playing during the fights as well)
