In the spirit of the deregulation movement, Japan is faced with an ‘Asia Open Sky’ agreement that favors liberalization in international airline services. This means an end to Japan’s aviation policy of isolation. Recently, Low Cost Career （LCC）, a new business model with low costs and low prices in the airline industry, is garnering attention in Japan with the above mentioned Asia Open Sky agreement. Actual services of LCC for one region affect the vitalization of the tourism industry, and economic benefits are anticipated from vitalization. LCC actual services are an extremely important policy for Hokkaido that depends heavily on the tourist trade regions. In this study, we developed a logit model on choice behavior in tourism regions, and analyzed the effects of LCC actual services on tourism from East Asia to Japan. The objective variable of the model was set as “choice probability of tourism regions”, and the explanatory variables of the model set as “airplane fare” and “attractiveness of sightseeing region”. This model especially focused on the “attractiveness of sightseeing regions” which is difficult to measure in existing studies. In this study, we defined the variable based on “brand force of regional resources”. Additionally, a newly developed “wintertime logit model” was incorporated with wintertime attractiveness as an explanatory variable. Using the model, we computed simulations that assumed a number of introduction levels in LCC related to the circumstances in Europe and Asia. Based on these results, economic ripple effects for advanced LCC actual service regions were estimated by an input-output analysis. From this analysis, we conclude that large positive economic value is effectuated for Hokkaido if the region LCC actual services are advanced. In contrast, if the region delays introduction of LCC to actual services, the model revealed significant negative consequences. Therefore, we propose a regional strategy and policy based on subsidies from the regional government to LCC actual service companies as landing and stationary fees.
