No waiting, bc that bus stop "Naruto Koen-Guchi" placed on Expway(high speed road) section.
https://goo.gl/maps/v7qvjBA4uJR2So you have to move to another local bus stop about 10 min by walk.
https://goo.gl/YfiY7H2nd bus stop name is "Naruto Koen" bus stop of "Tokushima bus".
Ferry port is not so far, get off 5th stop "Naruto kanko-ko(kou)" around 5 min short ride, 110Y/oneway.
This bus is regular local bus, no booking.

Tokushima bus has not "IC card" payment system,
only in cash, accept coins and only 1000Y bill(exchange to coins first when paying).
This 2nd bus stop area has also taxi waiting spot with like this,
https://goo.gl/maps/Z26S8LyPQWk(waiting one black colored taxi was recorded)
but waiting or not depend on date/time and weather conditions.
If no both(bus and taxi), try hitchhike catch local drivers, not so hard in this case.
Also you can go to observation spots until bus dep time if on weekday.
