    <p>This experiment was aimed at establishing the method of producing large fruits of loquat (<i>Eriobotrya japonica</i> (Thunb.) Lindl.). Using ‘Nagasakiwase’ (open field cultivation), ‘Mogi’ (open field cultivation), and ‘Natsutayori’ (plastichouse cultivation), we investigated the effects of different branch managements (only central shoot, central shoot + one lateral shoot, and central shoot + two lateral shoots) and flower cluster thinning rates (50%, 30%, and non-treatment) on fruit weight, branch structure and the canopy of the loquat. All cultivars in the treatment of a few bearing shoots had the largest diameters, fruit weight and number of leaves in both that and per fruit than other treatments. ‘Nagasakiwase’ at 50% and ‘Natsutayori’ at 30% flower cluster thinning rates had heavier fruit weights and larger bearing shoot diameters than other treatments. There was no significant difference in any of the treatments of ‘Mogi’. The relationship between the branch structure and fruit weight of all the cultivars was under r = 0.54, or uncorrelated. In ‘Mogi’ at 50% flower cluster thinning rate, plant coverage rate was low, and the sky factor area rate and photosynthetic active radiation (PAR) were high, but the leaf area index was the same in all treatments. All branch managements of ‘Mogi’ had the same plant coverage rates, sky factor area rate and PAR. Indicating that in order to produce large loquat fruits, it is effective to have fewer branches and improved light from the receiving environment of the canopy with a low fruit cluster rate.</p>
