During my time in England, I used the train a lot and was pleasantly surprised at how much things had improved with e-tickets, platform markings, and even trains arriving and leaving (more or less) on time! On the down side, there were a series of train strikes, unheard of in Japan, which I managed to work around. While regular trains were greatly improved, there is still nothing in the UK like the ultra-punctual high-speed Japanese bullet-train (shinkansen in Japanese) which has the remarkable record of never having had a single fatality or injury in over 50 years of running. Indeed, the excellent novel by Kotaro Isaka called Maria Beetle (マリアビートル) is set on the bullet train and the plot relies very much on exact arrival and departure times at stations!
Before getting on the bullet-train one thing you absolutely have to do is to buy an ekiben (駅弁), a very reasonably price boxed lunch (bentō=弁当)bought at a station (eki=駅) which contains a variety of small local delicacies. The Japanese take their ekiben very seriously - there is even an ekiben Grand Prix Contest held every year (see here for the most recent winner). So armed with my ekiben and two tickets - as well as the usual jōshaken (basic fare ticket) you also need a special tokkyūken (express ticket) to ride the shinkansen - I queued up in the designated spot to grab my unreserved seat (reserved seats are available but you have to pay more - personally, I've never needed to book except at the busiest times like New Year).
Inside the shinkansen is spacious, with plenty of leg-room, free Wi-Fi, and trolley service (though you should definitely buy your ekiben and drinks in the station - much cheaper with a lot more choice). Top-tip - if you're travelling from Tokyo to Osaka sit on the right and if the weather is good, you might be lucky enough to see Mount Fuji in all its glory - a quite breathtaking sight! The journey is remarkably smooth and bump-free, quite incredible considering the Nozomi's top speed is 285kmh (178mph)! Unfortunately, tourists using the Japan Rail Pass cannot use the Nozomi - instead you'll have to settle for the slower Hikari or the much slower Kodama. Another plus - the bullet train apparently has the lowest emissions per passenger of any mode of transport (apart from walking or cycling)! One final notable thing about the bullet-train is its cleanliness - the cleaners are famous for jumping on and cleaning in only seven minutes meaning train turnover is very quick (see here for a video on the "seven-minute miracle"). I'll finish with my own short video of the Nozomi leaving Tokyo Station and then a clip of it leaving Shin-Osaka Station after changing drivers - note the previous driver staying to check that it departs safely. COMMENTS, as always, are very welcome!
