ID Cafe bar is a BIG club with 3 different dance floors, one floor that has a cafe & bar, and the top floor has lockers for all your stuff.
It is in Nagoya, which is about 45 minutes away by train from Ogaki, and then another 5 minutes by subway once you get into Nagoya.  Nagoya is about 30 minutes away by train from Gifu City.  If you live in Takayama, Takayama is about 2 hours by train from Gifu City - so it is farther to go - but it is not impossible.  You may want to hook up with people in the Gifu City or Nagoya to make a weekend of checking out the bigger city areas.
