Shiretoko - bus schedule 30 April to 2 May

i'm building an itinerary for for my hokkaido trip this 30 april - may 11

the first leg will stop over at MEMANBETSU to explore the shiretoko peninsula...

i've tried to check the site for the time tables for MEMANBETSU to Utoro and Utoro to Shiretoko-Shari stations and i cannot find an english version.

So far these are the agenda that I have but i need to transportation timing.

30 April - MEMANBETSU to Utoro
30 April - YuuhiDai Sunset Point
1 May - Shiretoko Goko
2 May - Utoro return to Shiretoko-Shari to Asahikawa

The bus timetables for that period have not been published, but it is likely that they will be very similar or the same as the ones for last summer, as seen on the following page:
