Very weird place. I arrived with a 10 hour layover and planned to take the train to Osaka for a few hours. I passed through the transit checkpoint and went to the lounge to leave my hand luggage only to discover that once back in the departures section it was impossible to leave. I asked numerous personnel and no one had a solution. I was especially put off by the woman at the information booth who spoke very poor English through a face mask making the whole exchange a rather surrealistic encounter. Admitting defeat I spent the entire time at the airport and continued to be astounded by the paucity of restaurants and shops. Plenty of duty free but all with the same items. Plus for much of the time the airport was very empty. Also for a major entry point the absence of English signage was astonishing. Overall it was at best a tolerable experience. Would not do it again.
