The purpose of this study was to examine the impact of and responses to uncertainty avoidance and manufacturing culture as corporate cultures that have been identified as obstacles to the servitization of manufacturing in Japan. For the purpose of cultural comparison, a quantitative survey of manufacturing executives in Sweden and Japan, which have symmetrical cultures, was conducted. The analysis revealed that uncertainty avoidance, which was assumed to be higher in Japan in previous studies, was higher in Japan, and conversely, investment in long-term relationships with customers was higher in Sweden. On the other hand, most of the factors were found to have no effect on servitization in Japan, but only the perfection of quality in manufacturing culture was found to have a positive effect. In Sweden, uncertainty avoidance and Monozukuri culture were found to have a negative impact on servitization, and these factors that have a negative impact on servitization had a positive impact on service infusion. It is clear that in Sweden, uncertainty can be an obstacle for transitioning to a business with uncertainty such as services, while in Japan, on the contrary, perfection is pursued even in services.
