From Akatsuki Bridge in Tsukiji River Park to St. Luke's International University along St. Luke's Street, St. Luke's International Hospital side (opposite Time Dome Akashi), Kinshibai and Beyoyanagi are in full bloom.
It's the yellow part of the map
below.
Both Kinshibai (Kinito plum) and Byou willow (Mioyanagi, Beauty willow) are semi-deciduous shrub of the family Otogiriaceae, native to China and came to Japan during the Edo period. The flowering season is around June and July, and it is the same until the yellow flowers bloom, but the difference is that the stamens of the willow willow are long, many, and are well noticeable.

In both cases, yellow flowers will bloom one after another 
from early summer to summer, delighting our eyes.
