Since the first emperor, the National Bird of Japan (3Yen / 2009-07-27) has been the crow with a bad attitude, so it no wonder this
Kinky Kinki official of Ministry of Land feels the need carry a 6 inch (13 cm) knife as ‘Self-protection’ against the national, mutant, 3-legged crow (above left).
“Self-defense from the crows” – Ministry Official Arrested for Knife Possession Next to Schoolyard
October 16, 2010 | The Yomiuri Shimbun [edited machine translation] —Charged with possession of a knife in close proximity to an elementary school, Mr. Masaya Hanawa, the chief of the National Highway Office of the Kinki Regional Development Bureau of Ministry of Land was taken into custody at the Hushimi Kyoto prefectural police station. Mr. Hanawa (age 36 of Uji City, Kyoto Prefecture) was arrested on suspicion of violating of the Firearms and Swords Control Law [which prohibits carrying a knife with a blade 5.5 cm (2.5 inches) or longer*].
Around 7:30 am, Mr. Hanawa was found in the street next to the playground allegedly carrying knife approximately 13 cm [6 inches] in Fushimi-ward, Mukaishima CIty, Kyoto. He claimed to be carrying the knife in his briefcase, “for protection against attack by crows.”
Because several crossbow bolts [arrows] were shot into the school grounds a few days before, the police increased their patrols of the school. At the time of an arrest, suspect Hanawa was found peering over the school’s fence and upon a search the police found six bolts fitting a crossbow in the suspect’s briefcase.
The crows of Tokyo are aggressive as hell but carrying a six inch hunting knife is not really necessary. There would not even be a crow problem, but Tokyo is ruled by birdbrains (3Yen / 2005-02-07) who 20 years ago eliminated the use of covered garbage cans thus causing a massive increase of crows ripping open trash bags on the streets.
