I'm in Tokyo during sakura, or cherry blossom, season. It only lasts for about 2 weeks each year, so my timing couldn't have been better.Japanese people have sakura viewing parties, called Ohanami. It's a day out in the park, where eating and drinking copious amounts of beer and sake under the blossoms are the orders of the day. The atmosphere is festive, and I saw more than a few people already crunk by late afternoon. Yoyogi park was so packed, in many places you couldn't even see a patch of green grass.
