Vilnius, Lithuania
From late April through early May, you can see cherry blossoms in Vilnius at the Chiune Sugihara Sakura Park, named for the eponymous diplomat — the Empire of Japan's Vice-Consul to Lithuania — who helped six thousand Jews escape from Europe during World War II by issuing transit visas to Japanese territory. The park, created in 2001 on the 100th anniversary of Sugihara's birthday, overlooks the Neris River.
