Here's an interesting infographic by Skyscanner on where to see sakura in Japan, other than Tokyo. This map also mentioned how you can save on air tickets if you would book flights to places like Hiroshima or Kagoshima (even though there are no direct flights unfortunately). Nevertheless, it makes me feel like going, especially to Sapporo! Hope this will inspire you to travel too.
For those who might not have the chance to view them in Japan, I heard that there's also a sakura #blossombliss at Gardens by the Bay till this weekend, 26th of March!
