It is a matter of joy that the Ginza Line should celebrate its 90th anniversary ("Heart of Gold" in the Dec. 17 edition). The Ginza Line is one of the iconic institutes that represents Japan's technological innovation and economic prosperity, and I'm sure many old Tokyoites were soaked with nostalgia reading this article.

But I have mixed feelings.

Major fixtures located in metropolitan areas draw attention thanks to the areas' economic power and large population, while a lot of historic remains and infrastructure in dispersed areas are overlooked and abandoned. I think that this phenomenon is one of the ramifications caused by Japan's excessive centralization.
