The Konoha Sealed Hall is a location appearing in the Naruto Shippūden: Ultimate Ninja Heroes 3 and was stated to have been around since the creation of the village.
Located on the outskirts of Konohagakure, the Sealed Hall is built into a cave and has a torii gate at the front. As its name suggests, is protected by a powerful seal which only a master of fūinjutsu can unseal. It is used to store up powerful kinjutsu, including the Demon Shinki. The members of the ANBU from Konoha apparently also go here to conduct experiments. Shinga would later return here to retrieve the Demon Shinki and infuse it into himself.
