The PS4 demo of Koei Tecmo’s Toukiden 2 has been available to Nico Nico premium members for a little while but it has now been published for everyone.
If you want to download it, you need to open this link making sure that you’re not logged into a non-Japanese PSN account, or in an incognito window.
You will need a Japanese PSN account to download the demo, but after that, you’ll be able to play it on any account, provided that your PS4 is set as the primary consoles for them all.
The demo is actually very enjoyable, and doesn’t really require understanding of Japanese to play. It also gives a taste of the game’s open world, so it’s a good glimpse on the title before the Japanese release on June 30th for PS4, PS3 and PS Vita.
Incidentally, no PS3 or PS Vita demo will be released, so this is all we get.
