On April 16, 2010, the polar bear cubs moved to the Kaiyukan where their parents were living. The cubs are now more than 6 months old and have grown so large that it has become increasingly difficult for the staff to raise them directly, so it was decided to move them to a place where they can be raised without the staff having to go inside directly.

So far, the cubs have been moved four times. When they were small, they quickly became accustomed to their environment, and we thought they would quickly adjust to this move as well, but there was a bit of a hiccup.

Before the move, we decided to take the cubs to an exhibition hall that had been renovated for cubs. We thought they might get sick because of the change in environment. They walked around, sniffing the new place and checking out the exhibit space, but they didn't seem particularly excited, so all of us were reassured that they would be fine.
On April 16, they finally moved into their new exhibit space. When we put one of them in the room with us because they seemed calm, they instantly started to walk around anxiously. Furthermore, when we moved them to the bedroom, the cubs' anxiety seemed to reach a climax and they started to shout, "Whoa! Whoa! The cubs would squeal and yelp if a staff member was near them. The cubs would have stopped their cries if a staff member had been around, but that would have been pointless. We decided to leave the place with a grim determination, as it was where we were going to spend the rest of our time.
An hour or two passed, and they were still screaming so loudly that even the outside of the building could hear them. We became concerned when it seemed that it would not stop whimpering forever, so our staff had to stay next to the bedroom that day.

Perhaps because he mewed all night long, he was hoarse by the next morning. The staff felt sorry for the cub and went inside the exhibition hall, where the cub hugged the staff and sucked on his jumper. The jumper worn by the staff resembles the rubber of a bottle nipple given to a cub when it was small, and is one of the cubs' favorite things. It clung to the staff more tightly than ever, as if to say, "I missed you, please don't go away. It was as if they were saying, "We missed you, please don't go away. The only thing that reassured us was that even in such a state, he had a good appetite.

We worked hard to help the cubs get used to their new surroundings as quickly as possible, preparing a variety of toys and devising ways to feed them. Day by day, the cubs are getting used to the exhibit hall and their bedrooms, and customers can see how cute they look as they roll around and rub their bodies against the glass.

Looking back, this may have been a necessary test for him to stand on his own. When he was born, he weighed just 724 grams and was small enough to fit in the palms of both hands, but he has now grown to weigh more than 30 kilograms. So far, he has overcome the trials of adulthood one by one. When he was a small child, he was fed only milk, but he has started eating baby food. That he started sunbathing to strengthen his immune system and get used to the outside environment. They started practicing swimming. They started eating meat like their parents. We are happy to see them accumulate many more experiences and become adults, even though we are sad to see them go.
We are looking forward to their future growth and rearing them day by day.
