Ramen noodle shops are Japan's most popular category of restaurant. Yet within this ubiquitous, diverse, and highly competitive segment of the dining sector, particular clusters of restaurants stand out. These agglomerations are known as ramen gekisenku-ramen restaurant fierce battle zones. Through an examination of ramen-specific media and maps (magazines, comics, food blogs, university student handbooks, etc.) the paper classifies these clusters into three types: i) regional ramen-style agglomerations typical of small cities; ii) metropolitan neighbourhoods with concentrated diverse clusters of restaurants; and iii) purposely planned ramen theme parks. Each type has different morphological characteristics with divergent potentials for variation, innovation, and evolution. The paper argues that ramen's variety is a product of its geography, while suggesting that the circulation of place-based vernacular ramen knowledge, in the form of lore, stories, and other geographic cues sustains its capacity for innovation, most noticeably in the crucible of metropolitan ramen clusters.

This paper explores the location choice of multinational enterprises (MNEs) in China, shedding special light on the role of agglomeration of same-nationality firms. We examine how this role differs according to firms' productivity. Furthermore, we compare the location choice of Japanese and Taiwanese MNEs in China, taking into consideration that Taiwanese MNEs experience less uncertainty in investing in China due to Taiwan's linguistic and cultural advantages. When considering firms' productivity, we find that less productive Japanese firms prefer to locate close to larger same-nationality agglomerations while there are no differences in location choices in the case of Taiwanese firms.

This paper uses an extended case study of Japan to illustrate how surnames, or family names, can be used as a basis for regionalization. We undertake a comparison between inductively surname regions of Japan with areal geographies based upon both contemporary and historical prefecture (administrative) units. The work is seen as using highly disaggregate framework data to evaluate the integrity of the areal units that are used in regional science. It also is relevant to understanding population distributions, past and present, and the consequences of local, regional and national residential mobility and migration. [ABSTRACT FROM AUTHOR]

Abstract. Within this analysis we determine the optimal size (that is, with the minimum average cost) of a water supply enterprise and reconsider the matter of scale economies, using sample data from Japanese water supply organizations. After surveying evidence from previous studies of scale economies in the water supply industry, we estimate cost functions with three different cost models: the log-linear, translog and translog with a hedonic function. We obtain the result that economies of network density do exist, but that there are slight diseconomies of scale at the sample mean point. The optimal size of a water supply organization would be one supplying a population of approximately 766,000 people. [ABSTRACT FROM AUTHOR]
