“OMSI 2 Add-On: Project Numazu” is now officially on Steam!
Numazu City is now LIVE on Steam! 🌊
From the streets of Hong Kong (Project Tsing Yi) to the beautiful coast of Shizuoka, we are officially on the road.
Following the guidance from our publisher Aerosoft, we are committed to a Weekly Update Strategy. To ensure the best experience without overwhelming our users, we will consolidate all fixes into one major patch every week.
Developed by Aurora Studio & Negi-Kyu Workshop in collaboration with Germany Aerosoft GmbH.

Hello everyone,
I’m Shiko from Hong Kong, previously the author of Hong Kong Project Tsing Yi for OMSI 2.
Now I’m working on something new: bringing Numazu City (Shizuoka Prefecture, Japan) into OMSI 2 as a full add-on with Japanese buses and right-hand traffic.
About the Project
-
Location: Numazu, Shizuoka Prefecture (coastal city, famous for its port and seaside views)
-
Driving Style: Left-hand traffic (LHT), Japanese road signs and traffic rules
-
Routes:
| Bus Route | Destination | Route features |
| N12/N13 | Numazu Station ↺ Numazu Port | Short urban line, downtown streets, tight intersections, heavy traffic |
| N41 | Numazu Station ↺ Meidensha | Industrial / Factory Zones, workday shifts |
| N45 | Numazu Station ↺ Numazu Port | Scenic coastal route, seaside drive, landmarks, longer relaxed shifts |
- Vehicles: Japanese-style midibus and full-size bus (own custom models, dashboard, sounds, liveries)
- Scenery: Combination of realistic Japanese urban districts, coastal roadways, and small anime-inspired details as Easter eggs
- Professional Japanese Audio: Ambient sounds and announcements were created in collaboration with a Japanese sound team, ensuring every street and bus stop feels alive with the real spirit of Numazu.
Current Progress
-
Numazu Station area – detailed and lively, with realistic road layouts, traffic and buildings
-
Honmachi → Station section – looks good and nearly complete
-
Numazu Port area – under active development. Scenery build‑out and texture polish are ongoing, with regular updates planned!
-
AI traffic: includes Japanese private cars, taxis, trucks, emergency vehicles, Tour buses and Rail Trains from neighboring cities (Mishima, Atami, Fuji)
