The Japanese daily Sankei says it has obtained an internal government report outlining the requirements for building a nuclear weapon. The Japanese government denies that it intends to build such a device. However, public pressure has mounted following North Korea’s nuclear and missile tests.

The ... Sankei reported that experts at several government organizations concluded it would take at least three to five years to make a prototype weapon.
The experts also estimated that the project would cost about $1.68 billion to $2.52 billion and require the efforts of several hundred engineers, according to Sankei.
The experts did not say whether Japan should develop nuclear arms, the newspaper reported, only what such a project would require. The newspaper published a summary of the document, dated Sept. 20 and titled “On the Possibility of Developing Nuclear Weapons Domestically.”
