Getting to Kuji entails:
To find the best route to these stations, you may wish to use the Hyperdia timetable service in English (leave out the dash in Futako-Shinchi station to find it in the tool)
Exit out the north exit, and head towards the river. When you reach the path along the river, turn left and continue to head away from the station. You'll eventually reach some fields that are down from the road (there's a little mini-golf course between them and the river). Head down there, continue heading away from the station and you should eventually see discs flying.
Head out the (single set of) faregates and turn right. You'll come to a intersection with a pedestrian crossover. Either use the crossover or cross the street in both directions, then turn left. Take the next Right (after the conbini) and head down the side street to the second traffic light. Turn right here and follow the street down to the river road (you'll see an emankment and fields beyond it). Generally speaking we play to the right of here; turn right and then head in at the first road on the left (which will take you to the parking lot).
