Remaining in transit at Haneda?
 

As part of RTWs we often do a mileage run HKG-NRT rtn in A class. CX have now withdrawn First Class, but instead have an F daily service HKG-HND with a 747.

At Narita it was very easy to remain in transit. Got off the plane, walked a few hundred yards, went through an in transit security scan and re-boarded the same aircraft.

Does anyone know if the same procedure applies at HND, i.e. it's not necessary to enter Japan before departing?

According to Haneda Airport Web pages,

You don't need to go thru the immigration.

Thank you, Wasabi Tofu. Most useful.
