Konnichiwa! It's my first card from Japan, sent by Yukina. Tokyo Tower (333 m) is not as popular as Eiffel, but it's a prominent landmark of Tokyo. I knew it first time via a Japanese comic that I read regularly: Detective Conan. A few scenes in this comic shows Tokyo Tower :D. Now another new tower called Tokyo Sky Tree is under construction and will beat this tower since its height would be 634 m. Yukina said that after the March 11th earthquake, the antenna on the top of Tokyo Tower was bent. It must be shocking!
Two interesting stamps was stuck on this card. The bigger one depicts Japanese painting of flowers and tree, while the rest is a bee sucking honey from flower. Arigato gozaimasu, Yukina!
