Tokyo's Nikkei stock average closed up more than two percent at a one-month high on Friday on broad-based buying following the latest positive news on the Japanese economy. Investors scooped up banks, real estate and retail firms after economic data suggested that domestic demand, extremely sluggish in the past several years, may start to pick up. A weakening of the yen also encouraged investors to buy exporters, with Toyota Motor Corp <7203.T>, the world's No.2 auto maker, rising 1.62 percent. The Nikkei average <.N225> finished up 2.10 percent at 11,041.92, its highest close since January 23. The broader TOPIX index <.TOPX> gained 2.12 percent to 1,082.47.///
