The present situation of C. × yedoensis ‘Somei-yoshino’ and C. speciosa was compared with the status of trees (flowering level, tree vitality index), individual sizes (height, DBH, crown area) and planting environments (light environment, planting distance, occupied area, soil hardness, habitat classification) planted in Tottori University, which was integrated and relocated in 1966. Taking flowering level and tree vitality index as objective function, other individual factors and environmental factors as explanatory variables, the generalized linear model was used to analyze two species. The factors that affected the flowering level in both species were similar: crown area, light environment, soil hardness, habitat classification for ‘Somei-yoshino’ and light environment, planting distance, soil hardness for C. speciosa. ‘Somei-yoshino’ was planted first and is larger in size, so different management policies will be necessary for both species.
