Man'yō Botanical Garden, Botanical garden near Kasuga-taisha shrine, Nara, Japan.

The Man'yō Botanical Garden is a botanical garden near the Kasuga-taisha shrine in Nara that displays about 300 plant species mentioned in classical Japanese poetry. The grounds feature pathways through different planting areas, including a notable wisteria grove with hundreds of flowering shrubs.

The garden opened on 1 October 1932 on the former deer enclosure of Kasuga Taisha, designed by the landscape architect Ōya Reijō, who drew on the garden styles of the Heian period and consulted Kyoto's Shinsen-en and the Poseokjeong site in Gyeongju. The wisteria scholar Sasaki Nobutsuna campaigned for its creation from 1931, and the site was built as the first garden planted with plants from the Man'yōshū.

The garden draws its name from the Man'yoshu, one of Japan's oldest poetry collections, and displays plants mentioned throughout these ancient verses. Visitors can experience how closely nature and poetry were intertwined in classical Japanese culture.

The garden is located near the Kasuga shrine and easily reached on foot, with plenty of pathways for walking and exploring. One to two hours is enough time to comfortably visit all areas.

The garden's design by Ōya Reijō drew on two older landscapes: Kyoto's Shinsen-en garden and the鲍石亭 site in Gyeongju, Korea. Stone fences once built for the shrine's deer enclosure were reused in the garden. A 2021 relocation brought the Important Cultural Property Old Kasuga Taisha Board Storehouse (round window) into the grounds.
