Lately in Tokyo, I've noticed a significant decrease in the number of Mandarin speakers. The familiar Chinese-speaking staff at convenience stores have been replaced by Vietnamese employees. The most noticeable change is the large number of Indians. I even saw Indians setting up tents and organizing events in Minato Ward Park. Today, I also saw a large number of Indians at Ginza Pedestrian Paradise. The changes in Tokyo over the past two years are quite evident.
