Higashi Nihonbashi Station Accessibility

I'm staying at Toyoko Inn Tokyo Nihonbashi. Will be departing via Haneda Airport and I'd done research on Hyperdia.com for the best train route to Haneda. Found departure from Higashi Nihonbashi Station to be the best (Requiring no change of train). I need to know whether there is any exit at this station which has elevator/escalator to street level? We have fairly large luggage and lugging down the stairs from street level would be fairly tough..

Thanks,
Mel

Position of elevators and escalators, please try to translate here.

Thanks.. I went to the station to check earlier. B1 has elevator for south bound train (to Haneda) and A4 has elevator for north bound train (from Haneda).
