Chikashi Koizumi was a Japanese tanka poet. After initially working as a primary school teacher in his native Chiba Prefecture, he moved to Tokyo and became a full-time poet. He published in several prestigious poetry magazines, even helping to found both Araragi and Nikkō, before setting up his own poetic society, the Aogaki-kai, and taking on disciples. He died before the society's organ could see print.
