Kabukichō bar touts and inflated bills
Tokyo, Shinjuku and RoppongiOccasionalA tout offers a cheap drink deal. Inside, hostess charges, table charges and bottle fees produce a bill of ¥100,000 or more, and staff escort you to an ATM. Tokyo police have signposted parts of Kabukichō about this.
How to avoid it: Do not follow touts, who are technically illegal in Kabukichō. Choose bars with prices posted at the door.
