Japanese nouns do not change form for singlar or plural: you have to get the distinction from the context. Unlike many European / romance languages, nouns in Japanese do not have a gender associated with them (e.g.: 'la' or 'el' in Spanish).

Clicking on text that is red reads the sound of the word.

Challenge: can you identify which words below are "katakana words" (that is, words borrowed from English)? (Well, actually, Japanese borrows words from many languages, but this list happens to only include words borrowed from English.)
