By 1600, Japanese lantern clocks emerged as innovative timekeeping devices that not only told time but also played a role in early attempts at rhythm-based fertility tracking in East Asia. These clocks were intricately designed and reflected the cultural significance of time in Japanese society. The precision of these timepieces contributed to the understanding of time management and its implications for daily life and agricultural practices.

Japanese lantern clocks, utilized for fertility tracking in 1600, inspired haiku and seasonal poetry that elegantly linked the passage of time with natural cycles. Poets like Matsuo Bashō incorporated these themes into their work, enriching the emotional resonance of their verses and reflecting the interconnectedness of human life and nature.
