SINCE MID-1980S ROTARIES HAVE BEEN REEVALUATED AND WIDELY USED IN EUROPEAN COUNTRIES. THESE ROTARIES HAVE A RELATIVELY SMALL CENTRAL ISLAND AND THE OFF-SIDE PRIORITY RULE IS APPLIED TO THEM. MOREOVER, ROTARIES ARE CONSIDERED TO BE A USEFUL TOWN PLANNING TOOL, BECAUSE ROTARIES ARE SUITED TO THE TREATMENT OF TRANSITION ZONES AND BECAUSE ROTARIES LEND THEMSELVES WELL TO LANDSCAPING. IN THIS PAPER，THE TRENDS IN EUROPEAN COUNTRIES ARE INTRODUCED, THEN THE HISTORY OF ROTARIES IN TOKYO ARE REVIEWED BRIEFLY， AND FINALLY MEASURES TO REVIVE ROTARIES IN JAPAN ARE SUGGESTED.
