Noun (verbal noun/サ変名詞) + かたがた + Action
かたがた is a formal expression meaning "while also," "partly for the purpose of," or "at the same time as." It is used when someone takes the opportunity of doing one thing to also accomplish another purpose. The first purpose is typically the primary or stated reason, and かたがた introduces the idea that the speaker is combining it with another action or purpose.
This grammar point is quite formal and is commonly found in business contexts, formal letters, greetings, and polite speech. It is rarely used in casual conversation.
かたがた attaches to nouns (typically verbal nouns / サ変名詞):
Noun + かたがた + Action
The noun before かたがた represents one purpose, and the main verb at the end of the sentence represents the primary action that accomplishes both purposes simultaneously.
かたがた frequently appears with formal nouns such as:
Unlike the more casual ついでに ("while I'm at it"), かたがた carries a tone of deliberate purpose and formality. It implies that both purposes were planned or intended, rather than one being an afterthought. It is especially common in written correspondence and formal spoken Japanese.
