The N700 series Shinkansen trains have been in operation since 2007, and reach maximum speeds of 300km/h (186 mph). While not quite as speedy as Japan’s upcoming maglav train, these babies can get you from Tokyo to Osaka in just 2 hours and 25 minutes – they’re basically a miracle of modern engineering.

But it seems that some people out there do not respect the beauty of the Shinkansen. In fact, they look at all that shiny, white metalwork and see only one thing.

When Twitter user @amaharateikoku uploaded this cheeky tweet, they were greeted with a barrage of retweets from other people whose minds immediately jumped to the same place.

▼ “In the minute or so it took for me to realise this was a picture of a Shinkansen, I totally thought it was a peen!”

Oh dear. Do you see it now? Perhaps the designer could have made the rest of the train a tiny bit more visible…

Replies to the tweet mostly went along the lines of: “totally phallic, yep“, and also included a whole host of other dirty jokes and rudeness that we here at RocketNews24 have decided not to translate for fear of lowering the general tone.

Personally, we are shocked and appalled that the very symbol of Japan’s ultra-modern, mega-efficient, pristinely maintained transport system has been reduced to a simple online peen gag.

Of course, we at RocketNews24 consider ourselves above such things and remain committed to bringing you the most tasteful news from Japan and Asia.
