Presentata al salone di Ginevra '78, la Dome Zero è il primo tentativo di Minoru Hayashi di creare una supercar in piccoli volumi e omologabile per uso stradale.
Il progetto Zero non fu mai completato, schiacciato dai grandi costruttori nipponici e l'omologazione stradale non arrivò mai. Molta apparenza poca sostanza, la Zero montava in posizione posteriore/centrale il sei cilindri in linea Nissan di 2,8 litri e 145 CV (105kw), con un peso complessivo di 920 kg.

The Dome Zero was a prototype sportscar from DOME Co. Ltd that was exhibited at the 48th Geneva Auto Show. The 'Dome Project', started by Minoru Hayashi in 1975, had the goal of producing small volume sports cars using knowledge gained from his racing exploits. The Dome Zero was the first of such low volume sportscars, and after failed attempts at getting Japanese domestic homologation their efforts were concentrated on overseas homologation. The project would never be completed.
