In this paper, the challenges and possibilities of region-product based tourism managements are reviewed and discussed focusing on the example of traditional vegetables and GIAHS. The regional designations and product certifications can be synergistically utilized to facilitate sustainable tourism managements. Regarding the regional designations, there are various designation systems including the UNESCO's Man and the Biosphere Programme (MAB) and the Globally Important Agricultural Heritage Systems (GIAHS) managed by FAO. On the other hand, the product level certifications are utilized as well, including product certifications of environmental awareness or the Geographical Indications (GIs). The local products with strong socioecological connections with production areas can be registered as GI products. As the methods to connect the regional designations and products certifications, utilization of the methods of storytelling is demonstrated, and the need to consider the spatial factors such as accessibility of the local resources is discussed.
