"Kawamura NMT powered by NICT" which is available in YarakuZen has been upgraded (v.5.0) to support the latest NT engine.

 "Kawamura NMT powered by NICT" uses a translation engine which is developed by National Institute of Information and Communications Technology (NICT).

It is domestically produced, secure, and has a reputation for ensuring high security, because parallel translation data is not collected.

The latest NT engine offers significantly faster translation processing (approximately twice as fast as the version 4.x NMT engine, and approximately 1.1-1.3 times faster than the version 4.x NT engine), as well as better translation quality and fluency.

The following functions have been added and improved by this upgrade.

In the three specialised fields of General, Patent, and Finance, you can enjoy the high quality of translations. (Provided by Kawamura International Co., Ltd.)

Take this chance to experience translations of high quality.
