any amount of alcohol causes harmful effect on your body, but you gonna drink it anyway

and speaking of which, while Tokyo Metro Pass is a fantastic way to travel around the city ceter, you better not redeem the pass at small (non-tourist hotspot) station, especially from the station office. Because the chance that the pass has stored for a long time is high, and it may stop working unexpectedly.

if it stop working… you have to find a manned gate to pass.
