This is a question I have often heard from people I know who have visited Japan: why is customer service slow in Japan?
The answer is quite simple: quality service in Japan is measured by how long it takes.
The faster the service is, the cheaper it will be considered, and the lower the price will be.
Likewise, if a service is slow and/or takes more time, it will be considered as high-quality service, and this waiting time will justify the high price.
That's why when you shop, salespeople often take a long time to pack your purchase, to accompany you to the exit of the store, or that explains even why the shipping of your order will take a month!
It's pretty amazing for me as a Parisian, but what do you think? Do you have any experience with it? Let me know in the comments!
