Holding 100,000 JPY in your pocket is enough,  and you should take the invoice in a good condition. If you does not have a bank card, you only can get cash in the agent. In fact, there are a lot of ways to exchange money. When I was in Australia, I used the Epay wallet to send money to my family. If you are on a business trip, it is also suitable. and getting enough cash througt  the agent in japan just need a finger tip to provide the withdrawal code.  first download  Epay wallet at  Google play and Apple store, after that, the system will give you a bonus amazing of 10HKD !!
