Japan's Nikkei 225 stock index closed at its highest level for 18 years today (Wednesday).
It comes after the index rose to a 15-year high yesterday.
The Nikkei 225 rose just 0.3%, a much more modest rise compared with Tuesday's 1.9%, to 20,868 - its highest level since December 1996.
Shares have risen by around 20% so far this year and have been boosted by growing signs of economic growth in Japan.
