Whether or not you attempt to learn calligraphy is really up to you, but I would say that it’s likely that native speakers across the kanji sphere (China, Japan and Korea) tend to find forms that are similar to calligraphy more aesthetically pleasing: we’re all taught to use brushstroke characters as our models, after all. As such, it might be worthwhile to at least attempt to make your handwriting a little more like calligraphy.
As it happens, someone else very recently asked a question like yours, so I’ll take the liberty of posting a link to my answer here:
The first sections cover what’s available for learning the absolute basics of writing kanji (i.e. stroke order and general shape). I think https://kanji.sh is the best-suited resource for WaniKani users, and best of all, it’s completely free.
However, if you want to go further and learn how to write beautiful kanji, then you should consider the resources I mention further down, which include a calligraphy course covering elementary school kanji. Getting hold of a calligraphy course is going to make your life much easier in this regard, because without some fundamental ideas about calligraphy in your head, the best you can do is blindly imitate what you see in models, which can be difficult and frustrating. The only way to make calligraphy skills easier to acquire is to have guiding principles that allow you to ask and answer the question ‘what makes this kanji beautiful, and how can I improve mine?’ (The calligraphy course should also be, besides, fun reading practice.) You can also take a look at free resources like
- This calligraphy site: 基本的な点画を身に着けよう | 書道入門
- Calligraphers such as Kayo-sensei on Twitter
- YouTube channels like this one by a calligrapher called Takumi
The main issues with such resources is that they’re often brush-calligraphy-oriented, so they may not cover what you need to know personally. (In the case of what I’ve just posted, that’s not true, thankfully, at least in the case of the Twitter account and the YouTube channel, but more generally speaking, it’s true, because most native speakers have already learnt the basics of writing with a pen in school.)
Side note: the final section of the post above lists two apps (one for iOS, and one for Android) that can be used for studying kanji stroke order. I’ve very little experience with them though, so I don’t know how good they are for your purposes.
Finally, if you choose to take up calligraphy, you might also want to look at this old post, in which I made a list of a few of the features to look out for when trying to write kanji nicely:
I hope this is helpful. All the best.
