Hi, sorry if this is the wrong place to post. I saw this amazing Feudal Japan sample map in the Japanese RPG Maker Twitter, and I'd like to know if this is a pack that they've made available.
The tiles in the dock on the left looks very similar to the VX Samurai pack, but the roofs shown in the map is either new tileset or a revamp of the old stuff.
The flags and the bamboo patches are new additions as well.
It's probably the new assets for RPG Maker Trinity
Interesting enough, when I google RPG Maker Trinity the very image the OP posted came up on an article from Gematsu, so most likely idd.
Also I just found something saying that Trinity includes "Double Material Content compared to PC version".
