Tateyama
Do you know Tateyama-Kurobe Alpine Route? It's a very popular scenic route that traverses the Tateyama Mountain Range(a part of the Northern Japan Alps). The day before yesterday, I went to Murodo-daira to see the autumn leaves. Murodo-daira is the highest spot of this route (2450m).
This is Mikurigaike pond, the biggest pond in Murodo-daira area. There is a hiking course. You can stroll around the pond in about an hour. According to the guidebook "When you hike here, it is better to carry rain gear and wear appropriate footwear such as hiking boots." It was rainy day! The temperature was 8℃ ! (Toyama city's temperature was 23℃) So please check the weather beforehand !
