Transforming 'Chiwari' into Heritage Resources and Institutional Challenges in Urban Redevelopment in Historic-Building-Scarce Urban Areas

Q: What does this research mean for the field?

Pre-modern land divisions ('Chiwari') form the foundation of contemporary regional characteristics in historic-building-scarce urban areas, but their conservation during redevelopment is hindered by institutional challenges related to temporal gaps in incentives and a lack of objective criteria for evaluating historical value. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To examine how historical land subdivision patterns (chiwari) serve as urban heritage resources and identify institutional barriers to conserving them during redevelopment in areas lacking historic buildings.
Conducted spatial analysis across historical samurai residential estates and merchant quarters in the Kanda district of Tokyo, Japan.
Surveyed urban developers to evaluate regulatory and operational challenges in recognizing lot pattern preservation as a public benefit.
Pre-modern lot patterns directly shape contemporary urban neighborhood profiles by governing modern building dimensions and structural uses.
Identified a temporal gap between granting upfront redevelopment incentives and securing long-term maintenance of preserved lot boundaries.
Identified an evaluation gap caused by the absence of objective, quantitative criteria for measuring the qualitative historical value of lot layouts.
