This is an article about Izumi Kato from the "Wall Street International" but I thought it was very informative. They described Kato's way of using interesting tools like spatulas and his fingers to create his pieces. They also expressed that painting is like an extra-natural experience for Kato.
This website is interesting because like most others it includes Kato's works of art and his biography, but unlike other websites this one includes his auction results and events featuring Kato.
This was a pretty general website centered around Kato, but it features all of the important elements that are needed to understand his artwork like a biography, images, text, exhibitions and news.
