There are some phrases in my reviews that I always remember so easy due to them being in an anime or some other piece of media that I know, and the phrase just sticks in my head because I’m already familiar with it, and learning the kanji just feels extra satisfying.
Anyway, I wanna know YOUR easy to remember kanji that you saw/heard in Japanese media! Heres mine (which I’ve added a custom answer to, and unfortunately just burned. I’m gonna miss you 申し申し).
Like for the JJBA reference. 
thank you friend
My absolute favorite is 大丈夫! which you probably heard before as well.
仕方ない （or 仕方がない in WK）
it’s so useful in real life as well
Depends on the anime/manga you read or watch some phrases:
気を付けて - pretty common in Shounen action where the main characters friends often say before they go out for a battle or something.
海賊 - Not a phrase exactly but the terms is hard to miss if you have ever watched One Piece
有り難う - Super common
お客さん - If you’re into the Slice of Life genre then this one’s pretty common, especially in shows where the some character works at a shop, restaurant, etc.
One Piece has been pretty helpful for a lot of regular Kanji thanks to the devil fruits, cause a lot of devil fruits seem to be based on very simple everyday items (fire, wind, rubber, animals, etc)

though I didn’t notice the keigo お for a long long time.
Let me see. There are A LOT of words I know from anime that are super common, like 力, but here are some more obscure examples.
Aaaand I’m gonna stop for now or else I’ll make you a dictionary 
major props for the Aomine love. My mother is actually a huge fan and I sometimes catch her saying it too!

That’s the hardest sentence I could remember before even starting to learn Japanese. People who have watched a lot of anime can hear the feminine voice saying these words after the opening.
真実はいつも一つ!!!
Basically the thing detective Conan says all the time.
Some of the words that I’ve picked up from One Piece are:
かいぞく-pirate,ちず-map, なに-what,とみ-wealth,やった-hooray, ばか-idiot, and ゴム-rubber.
and おに (ogre) from Wednesday Campenella’s Momotaro
Nice topic
I always remember the りょく reading for 力 thanks to JJBA. “スタンド能力”
Also I think 代 appears in the One piece intro. Dai kaizoku jidai? Not sure about that.
Well, 時代(jidai) does contain 代
I guessed so from the definition of 代 but I didn’t know which Kanji used the first “Ji”.
Thank you 
Also from One piece, Mugi for wheat 麦
I still have problems associating the kanji with it’s meaning but once I know it’s wheat the next second I have mugi in my head
番組 - always hear it in jdrama “この 番組 blabla sponsor おくりします”
Wow, you’re be third one mentioning that sentence in the span of a few hours. I guess it is popular 
I don’t hear this phrase that often anymore. I guess you mostly hear it before an actual broadcast… Back in the day, when all the anime fan-subs came on an n:th generation VHS-tape, I heard it all the time. I kind of miss it. It makes me feel a bit nostalgic.
I’ve only ever heard this phrase used as a joke in 男子高校生の日常.
But of course there are a lot of items I learned from anime first, such as different numbers （一つ、二つ、…）, directions（右、左、…）and many many other things.
