Other mistake: On the plane, Akechi is reading, according to the dialogue, an "English newspaper." The newspaper is called "Global Times", but it's not supposed to be the real life one, which is a Chinese newspaper (albeit with an english edition); the logo is different. However, for being a Western-style newspaper (which is what Kindaichi calls Akechi out for), its front page is positioned wrong, like a Japanese newspaper.
