Japan's Topix index touched a record high on Thursday, tracking strong overnight gains on Wall Street, while solid corporate earnings from domestic firms reinforced expectations of wage growth, Reuters reported.

The broader Topix was up nearly 1 per cent at 2,993.14, as of 0206 GMT. Earlier in the session, the benchmark index hit an all-time peak of 2,993.21.

The Nikkei climbed 0.9 per cent to 41,151.07.

Both indexes were on track for a third consecutive session of gains, provided the current momentum holds, according to Reuters.
