Several studies have investigated the determinants of inbound tourism demand from Japan to Korea over the last ten years. This paper critically reviewed five previous studies which employed unit root test to identify the stationary of the independent variables. Results showed that even though some of the variables were not stationary, Kim et al.(2002) did not adopt cointegration test. As a result, the study was not able to rule out the possibility of spurious regression. Lee et al.(2006) resolved the problem by taking the relevant differencing of the variables in question. Park(2009) employed the cointegrated models, but the interpretation of the long run equilibrium model was not inappropriate. Park and Mo(2000) and Mo(2004) did not have any faults in the models, but the results of the two studies were quite different. Finally, among 5 studies, only Mo(2004) insisted that the korea-bound tourism was not a luxurious good for Japanese tourists.
