In Tokyo, there is a subway station named 「辰巳駅」(“Tatsumi Station”).
The Japanese kanji characters that spell “Tatsumi” are the characters for “dragon” and “snake”.
So, for that reason, every twelve years … including this year … that station is a kind of unofficial New Years station.
This is because 2012 was 「辰年」(“the Year of the Dragon “) and this year (2013) is 「巳年」(“the Year of the Snake “).
So, for this New Years, Tatsumi Station changed the signs in the station to read:
辰 → 巳
(Dragon → Snake)
