From Hokkaido to Okinawa Prefecture, 1,504 candidates are campaigning for the 480 seats up for grabs in Sunday's Lower House election.

During the 12-day campaigning period, which officially began last Tuesday, the candidates must strictly follow the rules stipulated by the Public Offices Election Law.

The problem is that some of the rules seem outdated or too rigid, while others — including the ban on campaigning online — can look somewhat ridiculous to outsiders.
