The second time I stayed in Tokyo with Manami Saitou and her family she waited in the airport for two hours while I went through security. The immigration officer was an overweight and balding man who looked only twenty-five but had the sort of begrudging indifference with the world I usually associated with a more elderly sort. He refused me twice because I didn't know Mami's exact address. Ultimately, I retreated to a different officer to get through.
