東北新幹線將會全線開業

Recently the FNN News reported the following:

12月4日の東北新幹線全線開業まで、あと2週間。新たに開通する八戸 - 新青森間で11月20日、一般向けの試乗会が行われた。
JR東日本は、12月4日の東北新幹線全線開業に先立って、新幹線「はやて」を体感してもらおうと特別試乗会を計画、全国から応募が殺到し、5,000人の定員に3万8,646人の応募があり、7.7倍の倍率となった。
選ばれた人たちは、一足早く八戸 - 新青森間を乗車し、陸上複線トンネルでは世界最長の長さおよそ26.5kmの八甲田トンネルで、区間最高速度となる時速260km走行を経験するなど、新幹線の速さと便利さを実感していた。
12月4日の開業後は、東京 - 新青森間は1日15往復、3時間20分で結ばれる。

For two more weeks, on December 4th, the Tohoku Shinkansen whole line would be open. On November 20, the general trial-ride fair was done for the newly opened Hachinohe to New Aomori line.
East Japan Railway planned a special trial-ride fair even if Shinkansen "Squall" could be experienced before the Tohoku Shinkansen whole line opening on December 4, application had poured in from the whole country, with 5000 capacity applied by 38,646 people, it became 7.7 times in excess.
The chosen people would be slightly earlier than others to actually feel the speed and the convenience of Shinkansen between Hachinohe and New Aomori when he got on it, and would experience the 260km per hour maximum section speed at the Hachikoda tunnel which was about 26.5km long, being the world's longest on land double-track line tunnel.

After its opening on December, the line would connect New Aomori and Tokyo by 15 round trips a day, in 3 hours 20 minutes.

I think after December 4th, travelling between Tokyo and the northern territories would be much faster.
