Thank you so much for the detailed explanations!

Hi Rio The word you were looking for was 'platforms,' to describe the place that you can go up to in order to see the views over Tokyo. This place sounds great.. We also use the word "platform," to mean the thing that people stand on whilst they are waiting for a train. There are other uses, too, but they are less literal. For example, if somebody is doing a difficult task that will take a long time to complete, we might say: "They have been working hard and created a good platform to build on." This means that they have put in some good work which should make the rest of the task easier to complete. Because a platform can be raised above the ground (like the observation one in Tokyo) we use platform in this way too to mean that somebody has started to achieve something.
