The cherry blossoms season has almost finished here in Tokyo. However, it is still not too late to enjoy the blossoms at Meguro river. I especially recommend the Nakameguro area (sometimes also written Naka-Meguro): Lots of food stalls, champagne with strawberries, funky fashion stores, bonsai shops and of course breathtakingly beautiful cherry blossoms along the river. It might be crowded, but it is definitely worth it.
