According to this link

there are two buses to Utoro (14:30,15:40) .

Returning from Utoro- Shari Stn the bus time is 10:20-11:20
Can you please assist and confirm I've read the information correctly?

Is there a direct bus from Utoro Stn -Abashiri? I'm visiting the Aurora drift ice station .
If not I can take the train from Shari-Abashiri.
Many thanks

Can you please assist and confirm I've read the information correctly?

Yes, everything except the spelling of the airport which is Memanbetsu.

Is there a direct bus from Utoro Stn -Abashiri?

Yes, the 10:20 departure from Utoro to Memanbetsu Airport also stops in Abahsiri along the way: at 12:14 at the boat pier, three minutes later at the bus terminal and another three minutes later at the station. Also, the 18:30 departure runs similarly. But apart from that I don't think there are additional buses directly between Utoro and Abashiri.

However, there are the following, additional buses between Utoro and Shari:
