Thinking that this would be of some help to them if they are interested in viewing autumn leaves during this period of time.
I have taken some news from 2 different websites for your references.
Little to know:
There are two types of leaves that you could view in Autumn when you are in Japan.
1) もみじ Momiji（紅葉、黄葉）= Red leaves/ yellow leaves Aka Maple Leaves
2) いちょう Ichou（銀杏）= Ginkgo leaves
**I will only cover about the maple leaves.
