Futaekagi 『 』

These are used for quotations within quotations.

Namigata ~

This is used to show range (from - to -), to show a long or drawn out vowel, to indicate music is playing or to show origin.

Kantanfu !

This is used the same way a exclamation point in English is used.

Piriodo .

This is used between the day, month and year in dates.
