Connecting time to international flight

I have book a domestic flight ANA at 7:30am from Chitose to Haneda. It's arrival time at Haneda is 9.05am. My international flight back home departure time is at 11:45am. I only have 2hrs n 40 min to connect between Haneda domestic to international airport.
Do I have sufficient time? If it is very tight, what can I do to speed up the whole process (there are 6 of us, young n old)? Is the transferring from domestic to international terminal in Haneda easy?

If your flight from CTS is not delayed, you will be fine. The check-in deadline for international ANA flights at Haneda is just 40 minutes before departure.

You should be asking ANA. If they booked the flight, then they know it's enough time.

According to my personal experience 160 minutes would be ample time for the transfer, providing as Firas said " no delay"

Thank you for all the inputs. My international flight is not ANA but Garuda. Therefore ANA will not be responsible if I miss my International flight. I am taking a risk therefore like to take means to minimise potential risk of missing my international flight.

Did you book the tickets as a single itinerary or did you buy the intl and domestic tickets separately? This will make a big difference in the event of irregular operations.

I bought the domestic and international flight separately. What are the chances of a delay for domestic flight. There are many flights out of chitose to haneda and I got the earliest one out.
If I am not wrong the next available one is 8:30am landing at 9:40am. Does it means I do have buffer?

I do have check in luggages so I may take a while to retrieve my luggages. Which one is more convenient..taking a shuttle bus or train from domestic terminal to international airport. ?

I think you have enough time for Connecting,If you will not delay.
You might already know,Garuda is requesting the check-in of up to one hour before.

Usually,most convenient way is shuttle bus.
You will reach to international terminal about 8min.
Departs every five minutes between 05:00 and 24:00 hours.
