i hv seen some japanese children clothings sold in this mall. the shop is located in the 2nd aisle near the main entrance. there are a lot of hats and socks in the front of the shop too. it is quite crowded actually.
i agree that the sales in this mall are very very inch.
You can go on friday. however, tuesday to Thursday are less wholesale customers. So if you go there on these days. The shop's sales lady might be more friendly.
