Flowering viewing is a thing that happens in Japan. I have no better way to set this up than that statement. In the States, some people go and watch the leaves change in the fall. In Japan, they go to enjoy the sakura (cherry blossoms) in the spring. I wrote a post about the national obsession with sakura (from blooming forecasts on the nightly news to sakura flavored everything) and in the post I mentioned the practice of hanami, or the flower viewing party. Hanami are basically just an excuse to get together with a group of your friends and/or family and have a picnic.
The hanami I went to was for the northern block of Miyazaki as well as some visiting Oita JETs. It was a lot of fun. I was there for about five hours, just hanging out, eating, and playing Cards Against Humanity. I even managed to take a few photos in the process.
It was absolutely beautiful weather, though it was a lot hotter than anyone expected.
