I was passing through Roppongi for work and was pulled towards the lights.
The sakura trees along the Midtown Garden are lit up every year. Yozakura itself is lovely but when they are lit up like this, it really draws a crowd. But surprisingly, at this time of night it wasn't too crowded and I was able to take a leisurely stroll along the park.
