The Otemon Square (追手門広場, Ōtemon Hiroba), named after and standing across from the main entrance gate of Hirosaki Castle, is designed as a stepping-off point for visitors to Hirosaki. It has an extensive sightseeing information center where travelers can get maps, pamphlets and advice about the city's sightseeing spots.
There is also a souvenir shop, a few restaurants and a small exhibition about local handicrafts and the Neputa Festival. Around Otemon Square stand a few of Hirosaki's early Western-style buildings, including the former city library, which was constructed in 1907. The library is no longer in use, but is open to the public.
