I'm currently in Japan on a 90 day visitor visa exemption with a Canadian passport and I'm going to Taiwan this Saturday. I've been in Japan for about a month now and I'm going to come back after 10 days in Taiwan. Will I have any problems getting another visitor visa exemption upon coming back to Japan ? Will immigration ask for an onward or return ticket ? I have a printout of my itinerary for a return flight to Hong Kong with a confirmation number from Cathay Pacific but not an e-ticket number since the ticket was bought with Asia miles. Will this be sufficient to prove that I have a ticket to leave Japan ?

Any help would be appreciated.
