The Japanese language has three different alphabets:
Kanji: Ideographic alphabet of Chinese origin. Every character represents an idea or concept.
Hiragana: Phonetic alphabet used mostly in combination with kanji.
Katakana: Phonetic alphabet used to represent foreign words, places, onomatopoeias, etc.
If the word is represented in kanji, the reading section shows how this word is read.
Words having multiple readings will be ordered by popularity.
Furigana
Furigana are the smaller kana characters, printed over the kanji to indicate their pronunciation. If the word has one or more kanji characters, its furigana will be written on top of them.
The transliteration can also contain the pitch accent representation for the pronunciation of this word. In some cases, the same word may have different pitch accents, and sometimes the pitch accent depends on the part of speech of the word. If that's the case, it will be represented beside it.

Warning about the quality of the sentences
All the sentences are imported from the Tatoeba project, a collaborative database of sentences and translations maintained by thousands of members. Also, most of the Japanese sentences were imported from the Tanaka Corpus. These were created by students as part of a project and in some cases they were not supervised by a teacher. That's the reason why the quality of the sentences may be inconsistent, and they may not sound natural sometimes.
Although there are many good examples too, as a general rule, as a general guide don't trust too much in the quality of the sentence.
If you have enough knowledge and want to improve the quality of an example, I encourage you to click on the open in tatoeba link and register to Tatoeba to update it.
