Feudal Japan, a samurai drama or a quiet village sim all need the same two things: believable architecture and a cast that fits it. Here is a combination from the shop that covers both for Unreal Engine 5.
The setting: a modular Japanese house kit
The Japanese Traditional Houses kit is built around 15 complete, fully furnished buildings that use only reusable kit pieces. Each house comes as its own level, plus a demo map with all of them.

Building types in the kit:
Details that sell the period
The description lists shoji windows, genkan and fusuma sliding doors (walkable), tatami on the real 0.9 x 1.8 m module, engawa veranda, tokonoma, irori hearth, kawara tile and thatch roofs, and post-and-beam frames. Furniture includes kotatsu, futon, low tables, tansu chests and andon lanterns, plus a Japanese garden set.
The product page also mentions 270 game-ready meshes with box collision and LODs, shipped as an Unreal Engine 5.8 project, FBX with textures and a Blender archive.
Cast for the scene
Three characters from the shop fit the theme. All are rigged and ship with an Unreal Engine 5.8 project.
Kitsune Mask Ninja
An adult ninja with a white kitsune fox mask and a topknot, a black kimono-style tunic with red clan crests, a red sash and armored black gauntlets. Rigged to the Epic (UE5 Mannequin) skeleton layout, with a full-body physics asset and 2 LODs at 14,927 triangles.

Samurai Cat
A humanoid black and white cat in ornate black and red samurai armour with gold details. It has its own skeleton with UE5 Mannequin style bone names and IK bones, 4 own animations (Idle, Walk, Run, Jump), a ragdoll physics asset and 4 LODs at 15,250 triangles.

Animations: what is included
The Kitsune Ninja and the Kimono Woman use the Epic skeleton layout, so the standard UE5 Manny / Quinn animations work through the included IK Rig and IK Retargeter. The Epic Third Person demo animations (Idle, Walk, Run, Jump) come already retargeted in the Unreal Engine format and are placed on the overview map. The FBX and Blender files carry 4 own in-place animations at 30 fps. The GLB holds the rigged mesh without animations.
The Samurai Cat has its own skeleton with Mannequin-style bone names, so you retarget Mannequin animations to it with the IK Retargeter.
Project ideas
Note that the character models and textures were made with generative AI tools; rigging, weights, animations and the Unreal setup were done by the publisher, as stated in each description.
