How big is the island of Odaiba (surface)?

Dear all,

I am doing some research on artificial islands in Japan and especially Odaiba and its history. Due to linguistic barriers, I am unfortunately unable to find any information on the actual size of the Odaiba islands. I would be very grateful for anyone willing to provide any informations on the matter.

Thank you!

Google Earth has measuring devices for point to point distances.

Linguistic differences shouldn't matter much because the size would be written in western numerals. Furthermore, provide a link to the text you've allegedly researched and people here can translate it.
I'm sure it isn't just that you're looking for an easy answer without doing any research.....

I did some looking yesterday in some of the usual spots (lists of Japan Islands and the like), but maybe simply measure it and calculate the area. Most of those artificial island are made up of regular polygons (ie, rectangles and triangles) with straight lines - that would give an approximate area.

BTW - the only number I saw was one you probably already have:
"Tokyo Bay includes about 249 square kilometres (96 sq mi) of reclaimed land area in 2012."

It seems difficult to find a reliable and useful answer to this question.

"Odaiba" is a nickname, and it refers to different zones.
In other words, which districts form Odaiba vary by sources.

You hope to know the size of (each) Odaiba island,
but I am not sure what you recognize as an island,
and there may be a source saying only a specific part of the island forms Odaiba.
(I seldom hear Odaiba called as island(s) in Japanese.)

A reclaimed land may be artificiality extended,
so a figure of the area
which is given without information of when it is measured or estimated
practicality cannot tell you the actual size.

Anyway, it sounds better to define your geographic scope of Odaiba;
otherwise you may be confused at different figures of the area,
due to the lack of one and only common definition.

To expand a bit on what omotenashi said, I've seen the term Odaiba used in two very different ways. Specifically, sometimes it's used to refer to the districts of Daiba and Aomi, but sometimes it also includes Ariake. (For example the Tokyo Big Sight convention center is often referred to as being in Odaiba even though it's located in Ariake.)
