Fujitsu held an open house at its research labs in Kanagawa, southwest of Tokyo.
The company said areas of focus will be technologies that interact directly with people and environmentally friendly applications.
In one example, researchers demonstrated a small, flexible sheet that uses differences in temperature to generate small electric charges of up to about 20 microWatts.
The company said it could be applied directly to the human body, using our body heat to power sensors, or on pipes at a factory.
Fujitsu also showed off new software that can quickly calculate energy use for data servers.
Complex temperature calculations usual take time and computing power.
But the new software relies on an existing database of configurations to quickly provide recommendations.
Also on display was a program that combs social media for trends and occurrences.
A demonstration using Twitter mapped mentions of crime onto a map of Tokyo, using both GPS and locations mentions within Tweets.
Fujitsu also showed a combined finger and palm reader, which it says will soon be able to identify someone from a database of 10 million, or about the population of Tokyo, in about two seconds.
The company also showed its interactive voice technology, which runs on smartphones and car audio systems.
As many Japanese words have the same pronounciation, Research Fellow Kazuhiro Watanabe said the system attempts to use previous querries and context to come up with the correct word for a situation.
