Osaka - Typhoon showers again washed out play in the Davis Cup world group playoff between Japan and Brazil on Sunday with the hosts on the cusp of victory.
Japan, who took a 2-0 lead after Friday's opening singles, were set to play Yasutaka Uchiyama and Kiwi-born Ben McLachlan against Marcelo Melo and Bruno Soares but the rubber has been further pushed back to Monday after a second day of rain, organisers said.
The home nation took command of the tie after Yuichi Sugita beat Guilherme Clezar 6-2, 7-5, 7-6 and Go Soeda edged Thiago Monteiro in five sets.
Japan, missing talisman Kei Nishikori through injury, need just one more win from the best-of-five playoff to return to the Davis Cup's top tier as they look to bounce back from a stinging defeat by France in February.
Japan have preserved their world group status with playoff wins in the past two years, largely helped by Nishikori's heroics.
