According to Monta Hayakawa and C. Andrew Gerstle, westerners during the nineteenth century were less appreciative of shunga because of its erotic nature. In the journal of Francis Hall, an American businessperson who arrived in Yokohama in 1859, he described shunga as "vile pictures executed in the best style Japanese art." Hayakawa stated that Hall was shocked and disgusted when on two occasions his Japanese acquaintances and their wives showed him shunga at their homes. Shunga also faced problems in Western museums in the twentieth century; Peter Webb reported that while engaged in research for a 1975 publication, he was initially informed that no relevant material existed in the British Museum, and when finally allowed access to it, he was told that it "could not possibly be exhibited to the public" and had not been catalogued. In 2014 he revisited the museum, which had an exhibition entirely of shunga "proudly displayed".
