Pay close attention to the Canadian Representative's Signature, he signed on the wrong line causing a chain effect of signatories signing on the wrong lines.

The US version has this corrected.

You mean the Japan-owned book of the document which was signed on 2 September 1945, right?
The document is called "Instrument of Surrender" [ koufuku bunsho in Japanese].
It directly states nothing about peace among the related countries, and it is not a general agreement as to the ending of World War 2.
Strictly it does not have a book of U.S. version, because it's not just a Japan - U.S.A. agreement. The other book of it was made for the Allied, not for U.S.A. only.

According to the Ministry of Foreign Affairs [MOFA] of Japan....
: The Japan-owned book of "Instrument of Surrender" is kept by the Diplomatic Record Office of the MOFA.
: A replica of the Japan-owned book is on display at an exhibition room in the annex to the Office.
: The book had some country names corrected after the ceremony, at which the representative for Canada signed in a wrong place, causing representatives of three other countries to sign in wrong lines.

Then what's on display at the 5F of the Edo Tokyo Museum, a copy or the real item that was moved there?

The Instrument of Surrender is at the Edo-Tokyo Museum like ExpressTrain states, the original copy.

Presumably the both items are replicas: the one is on display in the annex to Diplomatic Record Office of the MOFA, and the other was found by ExpressTrain at the 5F of Edo-Tokyo Museum.
Considering what the Office / the Museum exists for, I suppose it's more highly probable that the original book is kept by the Office than by the Museum.

The web site of Edo-Tokyo Museum suggests
: Items on Permanent Exhibition are changed twice a month.
: At its 5F the Museum has not only large two zones for Permanent Exhibition but also a smaller zone named "Second Special Exhibits Gallery" for exhibitions on particular theme(s), which are arranged 7 or 8 times in a year.

If the original book were considered to be an item which could be on easy-contact exhibitions, like those in Edo-Tokyo Museum, then the MOFA would not have needed to prepare its replica for visitors to the Office, I think.

Government websites are known for their up-to-date ness aren't they.

(sarcasm)

I'll contact the edo-museum and ask them directly.

The Qs & As page (by the MOFA) was modified for the last time at 2009-04-01T01:32:32, according to the time stamp. If so, the page is less than 6 months old; new enough, isn't that?

Anyway, I presume the purpose of the original question is to know where and how to see the Japan-owned book, regardless of whether the item is a real book or a replica.

omotenashi, the ORIGINAL is at the Edo-Tokyo Museum and is part of a permanent setting. It's not listed as a replica like many other items and you can get additional information there on it.

I recommend you actually visit the museum rather than relying on copying and pasting answers. It's a very interesting place and they always has fresh new exhibitions to keep it interesting
