What buildings are people not allowed to take photographs of in Japan? (from public street, no humans in pic)
<p>In Japan, what buildings are illegal to take pictures of?</p>

<p>Notes:</p>

<ul>
<li>Building only. Zero humans on the picture.</li>
<li>Taken from public street only. No entering private property/shops/transportation or similar.</li>
</ul>

<p><em>Context:</em> Loving architecture I always take tons of pictures when walking in the street, and sometimes get scolded by security guards. When talking with them they sometimes claim that some laws ban taking pictures of the building they protect, but without being able to tell me what law in particular.</p>

<p>You can take pictures of any buildings if you are in a public place, and can freely use such photographs without consent of a owner or designer of that building.  [Japan Copyright Act, art. 46]  </p>

<p>BTW, external appearance of buildings in U.S. Armed Forces facilities are NOT confidential under US-Japan Security Treaty and related statutes enacted in Japan. </p>

<p>At least, US military bases and affiliated facilities in Japan are illegal to photograph.  Here's the <a href="http://law.e-gov.go.jp/cgi-bin/idxselect.cgi?IDX_OPT=3&amp;H_NAME=&amp;H_NAME_YOMI=%82%A0&amp;H_RYAKU=1&amp;H_CTG=1&amp;H_YOMI_GUN=1&amp;H_CTG_GUN=1&amp;H_NO_GENGO=S&amp;H_NO_YEAR=27&amp;H_NO_TYPE=2&amp;H_FILE_NAME=S27HO138" rel="nofollow">Mutual Cooperation and Security Treaty under Article VI Facilities and Areas and the Special Criminal Act Attendant upon the Enforcement of the Agreement Regarding the Status of United States Armed Forces in Japan</a>:</p>

<blockquote>
  <p>日本国とアメリカ合衆国との間の相互協力及び安全保障条約第六条に基づく施設及び区域並びに日本国における合衆国軍隊の地位に関する協定の実施に伴う刑事特別法</p>
  
  <p>第六条</p>
  
  <p>　合衆国軍隊の機密（合衆国軍隊についての別表に掲げる事項及びこれらの事項に係る文書、図画若しくは物件で、公になつていないものをいう。以下同じ。）を、合衆国軍隊の安全を害すべき用途に供する目的をもつて、又は不当な方法で、探知し、又は収集した者は、十年以下の懲役に処する。</p>
</blockquote>

<p>Basically, violating the "confidentiality" (機密) of a US Army base by providing "documents, diagrams, etc" with a "purpose" of harming the Army is punishable by up to ten years in prison.</p>

<p>I got scolded by security guards in front of non-US buildings, so I guess this is only a partial answer. Other answers for other types of buildings are very welcome.</p>
