The Japan Wine Challenge, founded in 1997, is an annual wine competition held every summer in Tokyo. Every year, hundreds of wineries compete for numerous trophies and awards in various classes. Then – in 2008 a charitable event, basing on the Wine Challenge’s idea, was formed.

Being happy with the outcome of their first set of flyers and invitation slips, for their 2008 event – the Japan Wine Challenge decided to come back to Nichiai Creative for the design and creation of invitation slips for their upcoming get-together.
