Cash or credit card or debit card (blog by Luis)

It's OK.. it's alright..
Is it ok to carry over 100000Yen (roughly 1000Eur/$) in my pocket??
Some people feel more powerful and important whilst carrying large sums of money with them. I got used to carry and pay mostly with my debit card even for the smallest amounts both in Europe and America.
Here in Japan everywhere you go the payment is rarely made with card, either for small or large bills. You can even pay with your mobile phone. Not sure shops want to save on bank charges, just because Japan is most likely the safest country I have ever been, or some any other reason. But, it is alright around here to carry huge sums of money, especially for tourists who will surely find it difficult to spot an ATM which accepts foreign cards!
So far I only bought most things with cash, whereas my Japanese cash card is quietly resting in my wallet.
