been there once (osaka), a few isolated encounters made me changed my mind to visit that country again.

1) just alighted the train at a station and preparing to go to the hotel with my luggage, then saw a drunkard shouting "i will kill you" (in japanese, multiple times) at the platform, i just walked past and go to the nearest elevator, and then he took the same elevator with me, dllm. Luckily nothing happen, and he became normal again when see a station police.

2) bought something at a shop, then i heard the cashier asked me if i have membership card, I didn't understand, so i asked him in detail in japanese (i also know abit of japanese). He heard my accent does not sound japanese, he just raised his hand, and not answered any of my question, oh well, i just leave the shop then.

3) I asked for a steam bun at a convenient store (in japanese), the cashier ignored me totally.

Just a cold society, never feel like going there again.
