Talk:Nagai Nagayoshi

Cause of death
An edit from 5 days ago claims that Nagai died of a methamphethamine overdose. Is there any source for this? I couldn't find any sources for this, but I don't speak Japanese. And what does the Japanese Wikipedia say about his cause of death? 79.225.58.177 (talk) 13:40, 9 May 2015 (UTC)
