Walk into a company's building and apply in person

Hi,

Is this something common or acceptable in Japan? To walk into a building and apply in person by handing my CV and letter.

This post aims to be general for people who wonder the same (since I couldn't find a similar post).

Now, for my specific situation: I work in legal and wish to apply in big companies. I feel like I would just waste my day if I went company to company, giving my CV to reception desks.

I was recruited once with this technic in another country, but it was a small law firm.
