N もも — also, too
も particleReplace は with も to say “also” — when the topic shares the same predicate as something already mentioned.
グプタさんも 会社員です。
グプタさんも かいしゃいんです。
Mr Gupta is also an employee.
も takes the exact place where は would go and means “too / also”. It signals that the new topic gets the same comment as the previous one.
