Interestingly, that probably means that that photo is illegitimate. Photos of sculptural entities attached to architecture are considered copyright breaches in Japan, and Odaiba is certainly not old enough to have moved into PD.
What is copyright breach in one country, it is not necessarily in the other one. One cannot just impose laws to other countries, that is why countries are sovereign.
To impose copyright restrictions in other countries there must be either international agreement or the law in that other country that permits such limits.
