Japan’s terrific number of train otaku have already been treated to a carriage-themed clock, and now, these timetable obsessed citizens can sensibly save their money in this uniquely designed depository which, in these financially volatile times, may well be about as safe as a real bank.

Based on Tokyo’s Yamanote loop line, the product cleverly allows its proud owner to pop their money through the roof of the carriage.

Plus, if that wasn’t enough, the lights flash on and off,

along with the doors actually opening,

and closing.

Details which undoubtedly make it a must buy; however, incredibly it has one more tantalising trick — the ability to play train station melodies from a selection of stops on the line. A few examples of which can be heard by watching this dazzling live demonstration.

A final flourish that means Japanese train aficionados can now happily save up for their next trip while at the same time still feel like they are traveling on a train.

Does life get any better?
