The Nikkei 225 Index rose 0.4% to above 38,200 while the broader Topix Index gained 0.2% to 2,791 on Tuesday, with Japanese shares extending a winning streak to a third straight day as investors awaited further developments from ongoing US-China trade talks.
Trade representatives from both countries held discussions in London on Monday, with negotiations expected to continue on Tuesday morning.
Local equities were also supported by a weaker yen, which continued to slide amid reduced safe-haven demand.
A softer yen enhances the earnings outlook for Japan's export-driven sectors and makes domestic assets more attractive to foreign investors.
Top gainers included Advantest and Sanrio (both up 3.1%), Disco (1.6%), Ispace (6.7%), and Metaplanet (4.3%).
