March 06-07, 2021 Kids' Guernica workshop 2021 was held in collaboration with " Hearts for the Earth" project in Nikko, Japan. This year the organizer tried a new style of the workshop to connect the real workshop with the virtual communication during this difficult time of the pandemic. Many heart images sent from U.S.A., Cuba, Belgium, and Nepal were printed on waterproof paper and pasted on the Kids' Guernica size huge canvas.
