I am from India.We visited to culture tourist information center for traditional culture experience program for foreign visitors " Japanese dance workshop" on 22nd September along with my 4 family members. Our timing to workshop was 1pm-2pm so we reached there at 12.45 as it is mentioned in their brochure and booking email. We went to 6th floor where they conduct the dancing workshop. As soon as we entered our tickets were checked and they let us go into hall. We were told to sit in hall where the faculty of the workshop were already there. We were told to put our bags away from us where blue mattress was there. No lockers were there to keep your valuable things. There were two people sitting behind us who looked suspicious. We ignored them and started to pay attention to the faculty members. My mother stood up to check her ticket which was in her purse but sooner she realized that her purse was not there where she kept it. We searched everywhere but no use. Then it clicked me that two person sitting behind us were not there. I went down on the ground floor to check but they were not there. We then went to police station and filed official complaint about theft. Our passports , mobile and more than 70000 yen were stolen from the center itself. Police checked the cctv footage and it was clearly shown that two people sitting behind us stole the purse. We were so surprised that center do not allowed any person inside without booking and tickets and how come these snatchers were sitting inside of it? It clearly shows how poor the security measure this building has which is co operated with Tokyo Government. We had so much trouble due to this theft from so much renowned building itself. In future if this type of incidents are happening then I have to suggest people not to visit the center as there are no security parameters.
