"A lot of investors are buying on dips, which shows that the mood is positive," said Masahiro Yamaguchi, head of investment research at SMBC Trust Bank.

"The global economic recovery will become more concrete as the year progresses, which benefits Japanese companies that are sensitive to global growth."
