I went to Tokyo Sea Life Park today and its admission fee was 700 yen ($7.07 €5.38). There was no charge for elementary school kids. As usual there were many guests, I could not see fish well, but rear of the heads much.
Once one penguin escaped from this park. A neighbor civilian found a penguin who swam in the river near the park. We do not have nature penguins in Tokyo, so the civilian reported it to the authority. Later the penguin was captured and returned to the park.
The following is the penguin corner and the escaped penguin.
He escaped from the park once.
