Just a question, I am traveling with my family from HKG to Osaka via HND. Flying with JAL arriving 8:30 PM then my connecting flight to Osaka is leaving at 12PM the next day. I will be staying in a hotel within T3 of Haneda. Will be checked through in HKG? and If I am or I am not I know there is a transit desk at T3 for JAL at Arrivals. Can i check in there for my connecting flight the next day and drop off my baggage at T3 Transit or Do i have go to T1 for everything? I will be traveling with 1 kid and a few luggage.
