Japanese Stable Diffusion
Hugging Face Blog
rinna Co., Ltd. fine-tuned Stable Diffusion on approximately 100 million Japanese-captioned images to create a text-to-image model that accepts Japanese prompts and generates culturally appropriate images. The Japanese dataset used was 1/20th the size of the English training data, requiring a two-stage training approach that first replaced the text encoder and then fine-tuned both the encoder and diffusion model jointly. Japanese Stable Diffusion can now interpret Japanese-specific terms like "salary man" and cultural expressions that don't translate well to English, enabling generation of images reflecting Japanese culture rather than Western aesthetics.
