The current edition is displayed under the banner of „The Wisdom of Nature” and it is linked with the supplementing theme „See the Beauty”. The leading concept of the Polish pavilion has been derived from the symbols which, in Japan, are well recognized and easily associated with Poland: Chopin’s music and the Wieliczka Salt Mine, a unique tourist attraction. The implementation of the pavilion's design is actually discussed by its author.
