Airport Taxi Service

Hello, please can someone recommend a taxi service for late night pick up from Haneda? we are a group of 5 adults with a lot of luggage. We are travelling in 2 days. Thank you

Where is your destination? When is your flight scheduled?

I guess most travelers who take a taxi from a major airport in Japan like HND are catching a taxi which is just available there rather than choosing a company or a service.

One taxi car of a typical size in Tokyo can carry up to 4 persons.
So, you are highly likely to need two taxies.
For rides to some certain areas in Tokyo, taxi fares from Haneda Airport are at a fixed rate in many cases.
A higher-rate taxi fares apply during late and early hours, which are 22:00 to 05:00 concerning Tokyo taxies.

Have you considered other public transportation modes?

@OP You really need to define "late night"... In any case, one company offering fixed rate taxis from Haneda to various places in the greater Tokyo area is Keikyu

For five people plus luggage, you will probably need more than one, however.

Try Nihon Kotsu 03 5755 2336. They speak English
and ask about Van Taxi.
