Connecting to Domestic Flight

I arrive in Narita Terminal 2 at 6.15am in the morning.

How long does it take to clear immigration and customs at that time?

I would like to take a budget domestic flight at 8.05am which depart at Terminal 2 to Chitose (Sapporo).

Is this sufficient time for me to make it?

If not,the next available flight is 1pm and that would mean a transit of 5 hours at the airport.

You have less than 2 hours, yet you have to clear immigration, collect your luggage, go through the Customs and still to find your connecting flight terminal, could be in terminal one ??? Not to mention the check in time for your domestic flight ??? Seriously, if I were you, I would go for the next flight.

Sorry missed it big time.
You will save time being in a same terminal. However, as far as I know, budget airline's check-in closes 30 minutes before the departure time.

You will be in the arrival lobby of Narita by 7 a.m.

So if all goes well I should be able to clear customs in time and make it without problems.

I am thinking of taking Vanilla Air and they depart at 8am for Sapporo. Their next available flight after that is 12.50 so I don't see myself waiting 5+ hours at the airport twiddling my thumbs.

Thanks everyone!

And of course thats all hoping your flight to Japan leaves on time and lands on time!??, Waiting for bags at the carousel and lining up for immigration check can be quick...or can be lengthy, It's impossible to predict accurately, I've experienced both, I hope you make your connection on time, but be prepared to relax at the terminal for a later flight.

but be prepared to relax at the terminal for a later flight.

And be prepared for an additional airfares; as budget airlines, most of the time, have no show no refund policy.

And if so, does ANA or other Japanese airlines like JAL, have standby rates which are heavily discounted?

Booking online, their rates start from $400++ one-way and that is expensive especially since budget airlines are 6000YEN.

Have you checked : http://book.jetstar.com/Select.aspx
They have 09.45 flight

Yes I did. They don't have a scheduled flight at 9.45am for a November departure.

I think my best option is to wait for Skymark to release its fare bookings soon I hope.

Then my last attempt would be with Vanilla.

Yes I did. They don't have a scheduled flight at 9.45am for a November departure.

More flights are now available for November:

Try to spend time in the Chitose airport; and visit the ramen village; the Ebi ramen is highly recommended :
