Let's take a look at the main kanji dictionary (漢字辞典).
There are 3 basic ways you can look up kanji:
'Look up via (on-/kun-) reading (読み方[音読み、訓読み]から探す)',
'Look up via radical-stroke number (部首の画数から探す)', or
'Look up via radical-reading (部首の読み方から探す)'.
We tried clicking on the 'あ' line in the '読み方から探す (Look up via reading)' section.
This means the first hiragana character in the reading is 'あ'.
If there is no second character in the reading, click on '二文字目なし (No second character)', found next to '読み方二文字目 (Reading of second character)'.
If there is a second hiragana character to the reading, and you know what it is, click on the corresponding hiragana from the list.
Notation-wise, a katakana 'ア' means that it's the on-yomi,
while a hiragana 'あ' means that it's the kun-yomi.
We tried clicking on the kanji '亜'.
We can find out various information, such as how it is read, the number of strokes, words that use it and so on.
As well as this, you can see Jouyou information (i.e. if/when the kanji is learned in school),
at what level the kanji appears in the kanji kentei test and more.
If you want to look up a kanji by its radical, you can either search via the reading (部首の読み方から探す), or by the number of strokes (部首の画数から探す).
Let's look at the 'Nandoku (Obscure) kanji (難読漢字)'.
There are options to 'View by Japanese syllabary order (五十音順に見る)', or 'View by category (カテゴリ別に見る)'.
There are 11 categories to choose from, including plants (植物), fish (魚類), birds (鳥類), country names (国名) and more.
The 'View by category (カテゴリ別に見る)' option can be found at the very bottom of the Nandoku kanji (難読漢字) page.
This is a chart showing officially approved kanji for use in people's names.
It is colour-coded to show how many kanji have been added to the list over time, and the year in which they were added.
Elsewhere on the site you can also view kokuji (国字), i.e. kanji that were made in Japan (not imported from China), radicals (部首) and more.
There is also a section of new information (新着情報) on kanji.
People who like kanji might find this kind of information is just what they want.
