I live in Japan so I thought I'd answer your question to Leif.
No worries what so ever about bring cigars into Japan, you're allowed up to 100 cigars duty free; actual law is 100 cigars or 400 cigarettes, or if a mixture of the two then 500 grams total weight.
As an ex-contractor in one of my "former lives" all of the above suggestions are good, but the one item that will normally always get a contractor back to complete the work as agreed or correct omissions / mistakes is making sure to have a "hold back" of 15% give or take of the agreed upon total contract amount. This 15% constitutes a good portion of the contractors profit for the job. Never pay the 15% until you are satisfied.
Just my "two cents".
