Day 3 (December 23rd, 2014)
In the morning, we visited a large shopping mall. It was very busy. Many shops and department stores were decorated for Christmas, you could also find gift stalls like those at the Christmas markets at home. Some shops were loud and bright, goods were advertised via loudspeaker. But despite the many people, there was a certain order, nobody pushed, everybody lined up in a queue in front of the cash desk without grumbling.
We had been invited for lunch by the former supervisor of our daughter and her family. So we could visit an original Japanese restaurant. The menus there were only in Japanese, there were no pictures and we would have had a hard time with ordering. But the supervisor was kind enough to order for all of us and so we had tempura and different sushi. We had a very nice conversation and learned a lot about the Japanese culture. The food was very tasty.

In the afternoon, we visited the aquarium of Osaka, the KAIYUKAN, which is located in the harbour area and very worth seeing. With a total water volume of 11.000 tons, it is one of the largest urban indoor aquariums in the world. In the centre of the building there is a gigantic 9-metre-high tank, which alone contains 5,400 tons of water. You slowly descend in a circle around this basin and can watch the fish (including a whale shark, rays, hammerhead sharks) from different perspectives. Very impressive.

After leaving the aquarium, we enjoyed a beautiful sunset over the sea in front of the aquarium:

We went back to the hotel by subway. This was also new and unfamiliar for us: You have to look at a board to see which route you want to take. There you can find the costs for the trip. After that, you pay suitably and get a ticket that you have to validate at the beginning of the trip. At the end, when leaving the subway station, you have to put it again into a vending machine. If you paid the correct price, you can leave the station through the barrier. If not, a signal sounds and you have to pay the difference. But thanks to the help of our already experienced daughter, we paid correctly and could leave the station without any problems.
