Updates:
- Chanel at Shinjuku Isetan had good service, little stock (at least what they're willing to sell to new clients in Japan) for bags and SLGs, but decent stock for shoes and rtw. I bought the black short cardigan from 23P.
- Chanel at Shinjuku Takashimaya had good service, no queue and the shop is spacious. Quite a lot of stock for SLGs and shoes, no popular bags e.g. mini 22 (am I stating the obvious? Lol) for sale to tourists but bags from previous collections avail. e.g. the heart-shaped version of pearl crush from 22K (?) I bought a 23S WOC.
- Chanel at Shinjuku Odakyu had NO customers in the store on a Fri evening, saw some top handle minis + white mini bucket bag on display. I didn't enter the store to ask if the display bags were allowed for sale.
Conclusion: despite the 1.55% commission that department stores will take from your tax refund, I think us tourists are much better off visiting the Chanel boutiques located inside Japanese department stores, instead of the stand-alone boutiques at Ginza and Omotesando.
