How the Modular Japanese City Map Packs Fit Together

DnDungeon's modular city battlemaps are designed to tile together into a larger Japanese-inspired TRPG cityscape. Instead of one massive map, you get individual sections that connect at the edges, letting you build your D&D city as large or small as your session needs.

How the Modular System Works

Every map in the modular city collection is built on a shared 8×8 grid. The edges of each map align with the edges of any other map in the collection. Place two maps side by side in your VTT, and the roads, terrain, and grid lines match up seamlessly.

The key principle is simple: all maps use the same grid scale, and the connection points along each edge are standardized to meet smoothly! Roads exit at consistent positions so they continue naturally into the next map section. The Modular Japanese City Streets pack has 16×16 square street tiles while the Modular Japanese Alleys & Streets pack has 8×8 tiles, and both naturally connect to all of the various maps included in the Mega Asian City Bundle!

Bridge & Connector Pieces

Some areas of a city need transitions between districts. The Alleys & Streets pack includes 8x16 bridge and connector pieces for this purpose. These narrow map sections let you link larger map tiles across rivers, gaps, or elevation changes.

What's in the Collection

The Modular Asian City collection groups all the relevant packs together, including:

• The Modular Asian Village pack (residential areas, market streets)
• Various city and town map sections (temples, docks, castle grounds)
• Bridge and connector pieces
• Wild & wondrous call-to-action setpieces

You don't need every pack to start. Grab two or three sections that fit your campaign, and expand later. Each map works as a standalone battlemap too, so nothing goes to waste if you only use one at a time!

Using Modular Maps in Your VTT

In Foundry VTT or Roll20, place each map section as a separate scene or tile them together on a single large canvas. The grid alignment means you can:

• Run combat on a single section, then move to an adjacent one
• Build a full city overview for exploration sessions
• Mix and match sections to create different city layouts each time

The maps are VTT-ready at standard grid resolution, so there's no scaling or manual alignment needed.

Planning Your City

Start with the sections that match your next session. A gang's hideout in the slums, a youkai night market, and the connecting streets between them gives you a solid three-section city core. Add a smuggler's dock & a mysterious magic shop as your party explores further.

The modular approach means your city can grow with your campaign rather than committing to a single fixed layout from the start!
