酷道だった国道421号　ドライブ　Route421　ノーカット　御園交差点　石榑北交差点　竜ヶ岳 Ishigure Pass

I'm driving along the notoriously bad section of National Route 421. It's been significantly improved now, and regular cars can mostly pass each other. However, it can still be a bit nerve-wracking when a large truck comes along. It's a shortest route from Mie and Aichi prefectures to Lake Biwa that I'd like to remember. #badroad #drive #Costco @4kchan
