That’s according to Erik Matsunaga, a local writer trying to preserve stories of Chicago’s Japanese community. At one point in Chicago there were Japanese American Boy Scouts at the Buddhist Temple of Chicago in Uptown, Japanese American bowling leagues, Star Market and the Toguri Mercantile Exchange.
