The Willard Intercontinental Hotel, Washington DC, USA.
Outside of Japan, Washington D.C. is one of the largest events commemorating the blossoms. The plantings of the cherry blossom trees originated as a gift in 1912 from the people of Japan to the United States as gesture of friendship and goodwill. Since then, the number of trees has expanded to approximately 3,750 trees of 16 varieties on National Park Service land. With quite possibly the best address in D.C. outside of the White House, The Willard Intercontinental Hotel is close to literally everything you would want to see in the capital - the Washington Monument (one of the hotel's rooftop suites, a bull's-eye window perfectly frames the monument), the Capitol, the Lincoln Memorial, the Smithsonian, and downtown business and theatre districts… So many monumental political events have occurred in this hotel but it isn’t just relying on its impressive history, the hotel remains one of the most luxurious in the city.
As early as 1860, The Willard housed the first Japanese Delegation to the United States, comprising three ambassadors and a retinue of 74 and 80 tons of baggage.
