#kanji is fun

Find the appropriate kanji to use when typing in the romaji/hiragana on a computer/phone

Since I started my Japanese studies during high school, the formal classes I was taking had me writing out kanji for homework in order to remember it and to be able to pass the quizzes and exams. So I spent many hours writing out kanji only to end up with hand cramps and ugly looking written characters. It took ages and the stream of kanji that I had to learn seemed endless. However, one benefit I quickly saw was that I was able to quickly adapt to typing in Japanese on a computer/phone because I was able to correctly identify the kanji that I had practiced, and knew which one to select when several choices came up.

In Japanese, many words have the same sounds but different kanji and meanings (these are called homophones). So when you type in the hiragana or romaji for a word into the keyboard, it will prompt you with a list of kanji to choose from. Being able to correctly select the right one is something I suddenly realized I could do one day, even if I hadn't used the word often. I knew and could recall a larger number of kanji than I thought, and I could eliminate any incorrect kanji for the word I was trying to use. Having a good solid foundation in kanji characters means that you don't have to go look up every word in the dictionary to check that you have the right kanji, and you also don't have to leave the word in kana because you can't guess the right kanji, but rather you are confident enough to pick the correct kanji for the word on your own. This makes typing more efficient and saves time!

Understand the meaning of a word just by looking at the kanji

When you know a significant amount of kanji and what they mean, sometimes when you encounter new compound words you can guess at what they mean. Or if you are like me and sometimes forget how to read words you are already supposed to know, you can magically relearn them by looking at the kanji and interpreting the meaning. So sometimes when I am reading text in Japanese and I see a compound I don't know, I can interpret the meaning from context and from my understanding of the individual kanji, and continue through the text without stopping to look up the word. This helps you to get the gist of a text without having to look up all the words, and is how you can start reading more advanced books or manga.

Guess at the pronunciation of a word from the kanji

On the flip side of the previous cool party trick is being able to guess how to pronounce a word by knowing the on'yomi and kun'yomi of the kanji, and therefore being able to guess at the pronunciation of a word. Unless the word has 人 or 生 in it. This helps most when reading out loud in class or to another person. It will also help you to feel smug about yourself while reading a book that is of a more advanced level and being able to determine the reading of several compound words in a row.

Understanding a new word using kanji clues

As an extension of the previous cool party tricks, I eventually reached the point where I could hear a word in conversation that I had never heard before, and figure out the meaning using kanji clues.

For example, not all Japanese people know English (shocking, right?), and busting out your phone to look up every single word you don't know can become burdensome in continuing the flow of a conversation. So, if I hear a word that I don't know during a conversation (and the continuation or flow of the conversation hinges on my understanding of the word), I will stop the person and either ask what kanji the word is written with, or if I have a guess I will ask "is this using the kanji for X?" This way I can gain clues to the key word without stopping the flow of conversation too much. (It's also a fun way to show off to Japanese speakers.)

For example, if you hear the word jishin (じしん) in conversation, and you aren't sure which meaning the speaker intended:

自信 self-confidence

自身 one's self

You can ask:

"Did you mean 自信 (jishin) with the "shin" from 信用 (shin'you) or did you mean 自身 (jishin) with the "mi" (another pronunciation of 身) as in one's body?"

Then the person can respond:

"Oh, I mean 身 (mi)! As in, 自分自身 (jibun jishin), or one's self."

Then, you can continue the conversation, having an understanding of what the speaker is saying and not having to take out your phone to translate as often. This also can give the person you are speaking to a better sense of your level and help them to tailor the conversation to you.

TL;DR: Kanji is Fun
