Tsuukin Kairaku: Chikan de Go!!

Midnight Sleazy Train. Some towns have legends of haunted houses or underground communities in the sewers. 

Both have chikans. Moreover, the main male character is quite the same ^^ 

Both of these shows have chikans, trains, and molestation in common. Xpress Train takes things to the next level by introducing a man who is the legendary master of Chikan-do: The Way of the Groper. Anyone who enjoyed Pervs on a Train (especially the first episode) will definitely love Xpress Train. Chikan-do: it will change the way you think.
