The purpose of this study is to clarify changes in the supply and demand of the domestic lily with increasing lily bulb imports and changes to production areas in Japan. I analyze changes in the regional linkage of lily bulb and lily cut flower production respectively.Import liberalization in the form of the exemption of isolation quarantine inspection for import lily bulbs in 1990 decreased the shipment of domestic lily bulbs. Conversely however, shipments of lily cut flowers increased. The import of lily bulbs triggered price competition between export countries and moreover, the bulb supply of domestic distributors has an influence on the supply and demand of lilies.According to a case study carried out in Horinouchi Town, Niigata, the bulb supply becoming vital to the production of lily cut flowers sees linkage move toward the international domain rather than linkage in the production area. Now, linkage between domestic production areas takes place, and is implemented based on the production conditions in every production area and the various stages of growth. On the whole, each regional linkage diversifies without completely shifting. We may be opposed to import lilies if we can create regional differences in production conditions in this country.
