Japanese domestic market - (wiki) The term Japanese domestic market (JDM) refers to the local market in Japan for Japanese-made motor vehicles and components

SO for a 1200 to be JDM, it would have what the Japanese delivered 1200s had....

i can think of three things:

- Sunny badges
- Fender Mirrors
- White wall tyres

anything else?

possibly those monsoon window shields, but not sure they were factory or just aftermarket bits?
