Akihabara stabbing incident June 8, 2008–yet Akihabara knife shop with “Japanese Only” sign up
Mr Arudou, Just call the shop and ask what it means. Don't be Japanophobia
The shop answered very politely,
"it means the shop sells the goods to foreingers, but the foreigners carrying weapon will be checked at the airport and the weapon will taken away
by the authority.If someone tells the shop how to say it in English, the shop is willing to change the sign."
I am not sure the above is right translation. Mr Arudou, why don't you call the shop and tell it how to say it in English.
Even Mr Arudo, a long time resident in Japan, cannot write Japanese, and I am not sure the translation is right.
The shop is willing to receive the commment; you are not.
