This study aimed to assess Japan’s recent local production for local consumption (LPLC) movement, with a special focus on vegetables in the Osaka city region of central Japan. After collecting statistics data from multiple sources, we determined the weights of the vegetables that flowed into the Osaka city region in 2003. To do so, we aggregated the 14 major vegetables into two categories according to their preservation properties: leaf and fruit vegetables, and root vegetables. We also calculated the energy consumption embodied in the vegetable flows into the Osaka city region in 2003. The results showed that vegetables consumed in the Osaka city region came from prefectures throughout Japan, the large majority of vegetables consumed in the Osaka city region currently come from remote prefectures, and this is associated with a high level of energy consumption. Scenario analysis suggested that a decrease of more than 3.7 × 105 GJ of energy inputs could be achieved through the promotion of LPLC activities in the Osaka city region.
