Keishichi Nakahara (1887–1933) was a Japanese illustrator and painter, a leading figure of lyrical painting (*jojōga*) active during the Taishō and early Shōwa periods. His career primarily focused on illustration for magazines aimed at a female and youth audience, such as the famous *Shōjo no Tomo*. His works are known for their depiction of young girls with slender figures, fashionable clothing, and large, expressive, sparkling eyes, often filled with a dreamy or melancholic emotion. In addition to his editorial work, Nakahara's art gained widespread popularity through the design of commercial products such as stationery, envelopes, and paper dolls, which spread his style widely. He is widely recognized as one of the pioneers of the *shōjo* aesthetic and an important forerunner of *kawaii* culture, his style having exerted a profound and lasting influence on subsequent generations of manga artists.
