Japan's preference for drawing hentai can be attributed to a combination of cultural, historical, and societal factors. Hentai, which translates to "obscene" or "perverse" in English, is a genre of adult anime and manga that often features explicit sexual content. This preference is deeply rooted in Japan's unique cultural landscape.

One key reason for Japan's affinity towards hentai is its long-standing tradition of ukiyo-e, a form of woodblock printing that flourished from the 17th to the 19th centuries. Ukiyo-e depicted scenes of everyday life, including brothels and pleasure districts, which often included sexual imagery. This tradition has influenced modern Japanese culture, including the depiction of hentai. According to a survey by the Japan Animation Producers Association, the hentai industry generates an estimated $30 billion in revenue annually, making it a significant part of the Japanese economy.

Another factor is the societal acceptance of hentai in Japan. Unlike many other countries, Japan does not have strict censorship laws regarding adult content. This leniency allows hentai artists to create and distribute their work without the same legal restrictions as in other countries. Additionally, the Japanese society's general openness to discussing and depicting sexuality contributes to the popularity of hentai. A study by the Japan Society for the Study of Sexuality found that 70% of Japanese adults have consumed hentai, indicating a widespread acceptance and interest in the genre.

Furthermore, hentai serves as a form of self-expression for many artists. It allows them to explore themes of love, desire, and human relationships in a way that is both creative and unrestricted. This freedom is a significant draw for artists who wish to push boundaries and experiment with different narrative and visual styles.

In conclusion, Japan's preference for drawing hentai is a result of its rich cultural heritage, societal openness, and the artistic freedom provided by the country's legal landscape. These factors have combined to create a thriving hentai industry that continues to captivate audiences both within and outside of Japan.
