From twitter (by japan_arts) on Sept. 30,
Rafał Blechacz during practice.
"I feel very happy to be here in Japan in the bicentennial year of Chopin's birth. I thought it over the recital program and decided to incorporate the Mazurkas and Polonaises, Polish folk music, which is important for me as a Pole". (Rafał Blechacz)
**The website of JapanArts provides Blechacz's message in more detail (Japanese) with another photo.
See ピアニストたちの素顔 (True faces of pianists).
He was interviewed by French media, too.
