    Tourism consumption is often analyzed using a spatial autocorrelation model. However, it is thought that this spatial weight matrix will change due to high-speed rail investment. In this study, we clarify the relationship between the spatial autocorrelation model and the multi-destination tourism consumption model that have been used to evaluate high-speed rail investment. We propose a method to estimate changes in the spatial weight matrix due to high-speed rail investment. Also, using this method, we calculate the change in the spatial weight matrix due to the opening of the Maglev line between Tokyo and Nagoya. Changes in the spatial spillover of foreign tourism consumption and changes in tourism consumption by international airport are then analyzed. The analysis reveals that foreign tourism consumption in Tokyo does not have a relatively large impact on the spatial spillover to regions along the Maglev lines. On the other hand, it is revealed that foreign tourism consumption in Osaka has a significant impact on the spatial spillover to Tokyo.
