ANA baggage allowance?

hi, I'm about to order domestic tickets online on ANA airlines website from Haneda to Okinawa
but I cant find the baggage policy, does anybody knows or has a link? I have to know if I have to pay extra, cause my luggage will probably be 23 kilos

I assume that you are arriving at Haneda from Israel? I know that if you are traveling on the same airline from Israel to Okinawa, then your luggage would be transferred through w/out any extra charge. However, if you are using different airlines for each leg of your journey, then it will be best to contact ANA directly through the link, as there may be a charge for the extra 3 kg.

Hope this helps :)

thank you so much guys!
so it's free up to 20 kilos, but I couldn't find how much for each kilo extra for economy, should I buy a small suit case in japan before the flight and put half of my things in storage and half in the smaller suit case? until I return to Tokyo?

It's not a per kilo surcharge for overweight luggage. Instead there are flat rates. You can see the tables here:

If you are going to Japan on a StarAlliance carrier, you may want to look into the StarAlliance Japan Air Pass, which offers the same baggage allowance as international flights.
