Makinohara Tea Plantation Course (Higashiyama + Kiriyama)

This course goes around the foot of Mt. Awagatake.
One lap here is about 15km, so it takes about 30 minutes, but it's quite intense with lots of climbs.
There are no traffic lights, but it's a little difficult to ride because there are trucks passing by in Nissaka.
If you go clockwise, it's downhill so you don't have to worry about trucks too much, but the course becomes more difficult.
The course around Kiriyama only has one traffic light and few cars, but since it passes through a residential area, there are some concerns about cars coming out of side streets.
By the way, one lap is about 10km and takes about 20 minutes.
Overall this one has a lower difficulty level.
