Mt.Awa is still so much snow left and definitely winter mountain right now. Winter mountain equipments are necessary.
A few days ago was snowing but since yesterday, have got warm so much, like real spring.
For next 2 weeks, melting snow dramatically. So even if you come to see MT. AWA but the race day would be completely different conditions.
So mind your conditions till the race day and have great race in MT. AWA, Niigata, Japan.
