Asuka and Nara evidence
Nabunken’s excavation study compares often straighter, stone-edged Asuka ponds with more irregular Nara ponds, sloping pebble beaches and scenic stones, while noting exceptions. It places change within exchanges involving the Korean peninsula and Tang China. Particular routes of transmission remain the researchers’ interpretations.
Ponds, halls and religious landscapes
Heian courtly and temple settings supported different gardens. Pure Land examples such as Byōdō-in arrange pond and hall together as a religious landscape. Later Muromachi gardens developed pond, stone and dry-landscape arrangements; these traditions overlapped rather than replacing one another in a single sequence.
Tea gave the approach new tasks
Practices associated with Shukō, Jōō and Rikyū connect small tearooms with roji development. The tourism agency’s account of Jo-an and Gen-an also emphasizes Uraku’s more elaborate preferences. Tea gardens therefore need not all express one identical minimalist design.
Daimyo gardens and visiting
Edo residences accommodated large pond circuits and places for hospitality. Katsura in Kyoto also uses a strolling arrangement, but with a different patron, setting and spatial organization. Sharing a category does not make two gardens interchangeable.
Preservation and reinterpretation
Modern gardens also involved new patrons and water infrastructure. Murin-an was built in 1894–1896 as Yamagata Aritomo’s villa, with a garden by the seventh Ogawa Jihei using Lake Biwa Canal water and open lawn. Present-day heritage use also involves reconstruction and public access: Jo-an and Gen-an roji were reconstructed from older drawings, while the Expo 1970 garden reinterpreted historical styles within a new landscape.
