1st of June head down south to Mt Fuji and Hakone and hire two very special cars from fun2drive.......
an AE86!!!!! And then a KGC10 SKYLINE!! We will get to drive them all over Hakone and the Fuji mountain touge! Visit the HKS factory. Meet up with a friend who will take us midnight driftng in the mountains! Living the JDM dream.
What a coincidence, I was just at fun2drive this weekend! Are you talking about this AE86 and Hakosuka?
I chatted with the owner there, and he is a really cool guy. He really knows his car stuff. I'm not sure if he speaks English though, I was chatting with him in Japanese...
If you ever feel like doing some hiking while you are here too, there is an excellent hiking course that starts from across the street of fun2drive, called "Kintoki Yama trail". It's why I was there

I haven't driven any of the cars at fun2drive yet, but I might try the Hakosuka maybe in July or so. Let me know how it is please!! (I know it will be amazing though

)
EDIT: I forgot to add... if you want to find people drifting at night around the Hakone/Fuji area, the most common place where that happens is near Owakudani hot spring (大涌谷)at 35.242942N, 139.018346E.
This is at Owakudani:
The second most common place is probably near the top of the Nagao Touge (長尾峠)at 35.259617N, 138.972695E. Other places rarely have people drifting on them....
If you want to see some people driving grip as well, people usually assemble on weekends for Touge Time Attack/Battles on Tsubaki Line at 35.161262N, 139.073966E.
