Japan’s shinkansen are all fast, which is how they earned their English-language nickname “bullet trains.” But with no numerical limit on speed, there’s always the possibility of getting from point A to point B even more quickly, and that’s what East Japan Railways (JR East) wants to do with a newly announced upgrade to its Tohoku Shinkansen route, which runs from Tokyo to Aomori Prefecture, the northeastern tip of Japan’s main island of Honshu.
Shinkansen travel at different speeds depending on which section of the track they’re passing through, and JR East wants to boost that speed by 23 percent, raising it to 320 kilometers per hour from 260, for the section between Morioka Station, in Iwate Prefecture, and Shin Aomori Station, in Aomori Prefecture. This would cut the travel time between the two stations by 10 percent, shortening it to 43 minutes.
The change will extend the Tohoku Shinkansen’s 320-kilometer-per-hour section, which currently consists of only the area between Tochigi Prefecture’s Utsunomiya Station and Morioka, by an additional 178.4 kilometers, encompassing the entire line north of Utsunomiya.

However, raising the shinkansen’s speed isn’t as simple as just telling the conductor to open up the throttle. Along with safety upgrades to the track, JR East also has to beef up its sound-absorption infrastructure, since a 320-kilometer-an-hour train can make a lot of noise as it whistles by. Starting this month, the company will be installing additional sound-absorbing materials, raising the height of sound-blocking walls, and extending the buffering canopies on tunnels between Morioka and Shin-Aomori.
The entire project is expected to be finished in 2027.

What's the use of large window if can't see the scenery with that speed? Comfortable seatings with low cost should be there instead.

Same price?

Only a short article but it's full of errors.
No, they earned that name from the shape of the first series of trains.
Other errors have already been remarked.

That's is a significantly higher energetic cost, will they not rise ticket prices?

I thought Tohoku Shinkansen was replaced 4 years back by Hokkaido Shinkansen which runs upto Hakodate.

No-they earned the name from the bullet shaped front of the original shinkansen trains.

While in Japan you talk of increasing the speed of your trains, over here the Oil lobby has so far successfully prevented the building of even one single bullet train.

Einstein would be shocked to hear that.

That's true. Air resistance is proportional to speed squared, so it'll be 50% more at 320kph compared to 260.

The Hokkaido Shinkansen will eventually get to Sapporo around 2030 and that is essentially the goal here. Without speed improvements, a bullet train to Sapporo from Tokyo will take too long and people will just continue to fly between the two cities.
