After purchasing a book and the "Chuo-ku Tourism Certification Past Questions" at Kyobunkan, I received a lucky coin voucher with a clover.
When I paid at the cash register, I received a voucher, so I received a coin on the 9th floor.
If you put this in your wallet and always carry it around, you will surely be lucky. Of course, the Chuo-ku Tourism Certification will also pass smoothly.
I'm looking forward to the annual performance of the handbell. Please see here for information on events at Kyobunkan. http://www.kyobunkwan.co.jp/
