Over at the official PlayStation site in Japan, Sony just released a total of six new titles demo for PlayStation Portable users. It should be remembered that Sony did the same last week, unloading a different set of demos including one for hit video game Gurumin: A Monstrous Adventure.

However, it seems that most of the games are learning simulation titles so it might be impossible to enjoy them fully if you lack Japanese comprehension skills. But a demo is still a demo and there's nothing to lose anyway because they are for free. The titles are as follows:

* Kanji Trainer Portable
* Brain Trainer Portable 2
* Computer Science Lab 1
* Computer Science Lab 2
* Homestar Portable
* Shichoka Crossword

Like we said the last time around, this might be the only chance we get to see these games so we will be trying them nonetheless. Take note that all of these demos require FW 3.40 to run.
