The variation in body hair among Japanese people is often traced back to the migration and blending of two distinct groups:

: Historically, a certain degree of hairiness was considered sexy or a sign of maturity. Some social circles still appreciate a natural look , viewing it as more authentic or "manly." Artistic & Cultural Symbolism

: Products like the No! No! for Men neo-laser razor are popular for removing "stray stomach hairs" or five-o-clock shadows.

: In some traditional crafts, such as scarf weaving , "hairiness" is seen as a feature of resilience and warmth rather than a defect.

: In contemporary urban Japan, there is a strong social pressure for both men and women to be hairless .

: People from regions like Okinawa (Ryukyuans) often share more Jomon traits, including more prominent body hair, compared to mainland Japanese who may have more Yayoi influence. Shifting Beauty Standards

: The Ainu people , largely concentrated in Hokkaido, are descendants of these earlier groups and are noted for having thick beards and significant body hair, which historically held deep cultural and spiritual significance.

: In folklore, creatures like the Kappa were originally described as hairy, monkey-like figures before their depiction evolved into the smoother, turtle-like forms common in modern anime.
