The Japanese art magazine 『国華』(Kokka) was first published in October of Meiji 22, which corresponds to 1889.
Notes on verification
Multiple independent institutional sources (university museum, national research institute, library catalog, encyclopedia) converge on October Meiji 22 (1889) as the founding date, though all likely trace back to the magazine's own publication records.
