When the boys' choir Boni Pueri last toured in Japan in late 2010, the group made a stop at Tagajo in Miyagi Prefecture, merely months before the Great East Japan Earthquake and tsunami destroyed a large part of the city. Upon hearing the news at their home in the Czech Republic, the group quickly organized a charity concert and donated the proceedings to Tagajo, where the venue of their concert in 2010 had been turned into a shelter for displaced families.
