Early X'mas shopping in Japan

It is still early for Christmas but the shops have started selling goods at discount rate. I was at the above shopping center and was quite surprise to have found a Daiso discount shop selling most items at 100 Yen which is equivalent to S$1.20.
I got a pair of shoes at 1,990 Yen ($24) from a shop selling sports items. The original price was 4,990 Yen (a discount of almost 3,000 Yen or $36).
Shopping in Japan is fun because the malls are huge and not as crowded with people as in Singapore. Besides, there are ample car parking lots and are free of charge.
