This is a hillclimb I highly recommend. 1300m over 25km, finishing at an altitude of 2127m.

Last year the race was shortened due to snow at the top, but unlike Kusatsu (which suffered the same fate) the cutoff point was still a reasonable race of 800m over 15km.
It is one week prior to Kusatsu, so it could also be used as a good warm-up event.
Last year's report is here:
