長野原草津口 refers to Naganohara Kusatsuguchi
草津温泉 refers to Kusatsu Onsen bus terminal

毎日 means they run everyday
★ means they don't run on weekends and during school holidays
平日 means they run only on weekdays
土休日 means they run only on weekends and public holidays
● means they run only when the temporary Kusatsu limited express train runs

Thanks a lot, do i need to book anything in advance?

It is a local bus for which seat reservations are not possible. You just go and board.

The bus schedule is planned to synchronize with train arrival. When I got there, there were 6 buses in standby. 5 buses got full and the 6th bus was not utilized.
