Meeting a Japanese customer for the first time is always exciting. First impression is the best impression, so please go on time in proper suit.
Ensure that you go on time.
Punctuality is very very important.
+ Go in a simple formal suit with tie and formal shoes
+ No Blazer
+ If suit is difficult for whatever reason, follow the seasonal dress code which is CoolBiz or WarmBiz
+ First impression is the best impression
In case if you are meeting the customer along with your boss/manager or sub-ordinate, there are certain hierarchical guidelines to be followed.
