仲良し | A good friend. |
仲間 | Friendship, as in “This event affected our friendship.” “Our friendship grows by the week.” HOWEVER, usually 中間 is NOT used to mean friendship, but to mean membership in a group (i.e. working for the same company, OR “The squid is the octopus’ 仲間.” “The salamander is the frog’s 仲間“) |
