Hi! I have an overnight layover at HND due to flight timings JAL DFW-BKK in Biz... as I understand I must remain airside during the overnight layover due to japan entry restrictions, wished to kindly ask what kind of options remain at HND for sleeping during the overnight layover... as I was in J, was the Sakura lounge open throughout the night and did it have sleeping or resting rooms? furthermore were there any capsule hotels or any other sleeping arrangements available airside? where can I find out more info?
