Oneworld Yokoso Japan Pass

if I want to fly fr Hakodate to Kanazawa(Kormatsu Airport), which need to change flight at Tokyo, will this be considered as 1 fare or 2 fares by using Oneworld Yokoso Japan Pass?

It will be considered 2 sectors.

Dear Uji,
1)So, fr Tokyo to Kushiro is consider 1 trip, and fr Sapporo to Osaka(Itami Airport) also consider 1 trip, am I right?

2)If I want to go to Kyoto fr Hokkaido with flight, is Itami Airport the nearest airport?

3) Does Oneworld Yokoso JP covered Singapore Airline?

Thanks

So, fr Tokyo to Kushiro is consider 1 trip, and fr Sapporo to Osaka(Itami Airport) also consider 1 trip, am I right?

Yes. Direct flights are considered one sector.

If I want to go to Kyoto fr Hokkaido with flight, is Itami Airport the nearest airport?

Yes.

Does Oneworld Yokoso JP covered Singapore Airline?

No! Singapore Airlines is member of Star Alliance, not Oneworld.

The Star Alliance air pass is valid on all domestic flights by ANA.

ANA also operates on the Tokyo-Kushiro and Sapporo-Itami routes:
