Saitama Prefecture and Tokyo City are parts of Tokyo metropolis.

For comparison: Chengde prefecture level "city"
area 39 519 square km
population 3,610 millions
The area is about as big as the four prefectures of Tochigi, Fukushima, Miyagi and Iwate combined. But those 4 combine to a population of 7,5 millions.
Chaoyang prefecture level "city" - area 19 698 square km, population 3,045 millions
Fuxin prefecture level "city" - 10 445 square km, 1,819 millions
Jinzhou prefecture level "city" - 10 111 square km, 3,07 millions
Shenyang prefecture level "city" - 12 942 square km, 8,106 millions.

If you normalize it by density the picture changes a bit.

Aomori Prefecture - 143 ppl/km^2
Iwate Prefecture - 87 ppl/km^2
Miyagi Prefecture - 319 ppl/km^2
Fukushima Prefecture - 140 ppl/km^2
Tochigi Prefecture - 307 ppl/km^2

Chaoyang prefecture level "city" - 91 ppl/km^2
Fuxin prefecture level "city" - 154 ppl/km^2
Jinzhou prefecture level "city" - 174 ppl/km^2
Shenyang prefecture level "city" - 626 ppl/km^2

However a better comparison would be to count the pop within 50km or something of a station. I could imagine that most of the population density in the Japanese Prefectures hug their respective HSRs more closely than the Chinese ones given the geography. The Beijing Shenyang PDL just skirts over the top of Jinzhou in Heishan County while most of Jinzhou's population is located in the south. Of course comparison between those two corridors are not perfect. With the Beijing Shenyang PDL being anchored by two large cities (from a global perspective) on both ends while the Joetsu Shinkansen just has Tokyo on one end.

China is building high-speed railway station under Great Wall

http://www.chinadaily.com.cn/china/2...t_30305505.htm



Chinese workers are building the world's deepest and Asia's largest underground high-speed railway station beneath the Great Wall at the Badaling section in Beijing.

The station under construction will be 3-story high and have a 36,000 square meters floor area, including platform, entrance and exit. The railway tracks will be 102 meters underground.

The station is an important part of a 12.01 kilometers long tunnel section of the 174-kilometer Beijing–Zhangjiakou high-speed railway line. The tunnel is the longest one of the railway line.

"Passengers will enter and exit the station about 100 meters underground, and it will be very safe," said Dai Longzhen, a senior manager of the construction company China Railway No 5 Engineering Group Co Ltd.

An escalator would raise passengers 62 meters at vertical height, and inclined elevators will also be used in the station for the first time.

To secure the safety of passengers, the station will change the inclined shafts that are used to build the station as permanent rescue channels.

The underground burrowing work is the country's most complicated, because the station has to contain 78 caverns and lots of intersections, said Chen Bin, a commander-in-chief of the project.

Starting from the construction of the tunnel on April 15, 2016, workers have known how tough the work will be, however the hardness of the rocks still exceeded their expectations, said Jiang Si, a manager of the company.

According to its initial plan, workers could excavate the tunnel 6 to 8 meters a day, but the tough rock meant workers could dig only about 2 meters a day.

Large–size shield tunneling machines could not be used, and workers could only use the blasting method in the construction, Dai said.

"The No 1 shaft has a 80-degree turn, and the No 2 shaft has a 135-degree turn, which prohibits the machines more than 100 meters long from working there," Dai said.

Workers have to develop new blasting technology to explore the tunnel carefully, because just above it are the Great Wall and the railway line linking Beijing and Zhangjiakou first independently designed and built by Chinese 100 years ago.

Workers have carried out more than 4,500 explosions. They use the electronic detonators to control the vibrations in batches of small explosions to reduce the impacts on the inside of hills and the Great Wall. At the Qinglongqiao station of old Beijing-Zhangjiakou railway line, worker used expansive agents to dig the tunnel, only 4 meters beneath.

Another problem in the tunneling is the underground water, and every day, workers have to pump at least 19,000 cubic meters of water, which equals about 10 swimming pools.

The Bejing-Zhangjiakou high-speed railway is expected to get through by the end of 2019, allowing passengers to travel between the two cities in one hour. It is an important project for the 2022 Winter Olympic Games.

China's high-speed trains becoming the preferred choice for travelers

Not only does China have more people than any other country on the earth, it also has the largest migrant population.

Jiangsu to Build High-Speed Rail Network to Foster City Cluster Development Along Yangtze River

https://www.yicaiglobal.com/news/jia...-yangtze-river

(Yicai Global) Aug. 1 -- Jiangsu, East China’s economically advanced province, is building high-speed rail network to form a more connected city cluster among its major cities along the Yangtze River. The Jiangsu Provincial Development and Reform Commission and relevant departments in eight cities along the Yangtze River are drafting an implementation plan, Yicai Global learned.

The planned rail network will form a high-speed rail connection in the city cluster along the Yangtze River to create "one-hour commuting circle” in the region.

The Yangtze city cluster covering eight cities along the Yangtze River, namely, Nanjing, capital of Jiangsu province, Zhenjiang, Changzhou, Wuxi, Suzhou, Yangzhou, Taizhou, and Nantong, has a per capita GDP of more than CNY120,000 (USD17,647), contributing about 80 percent of the total provincial economy in Jiangsu and is one of the regions with strongest comprehensive competitiveness in China.

Building Yangtze River city cluster will be conducive to economic integration and transformation and upgrading between South Jiangsu in the south of the Yangtze River and Central Jiangsu in the north of the River, Wang Shuhua, associate research fellow at the Institute of Regional Modernization Research at Jiangsu Provincial Academy of Social Sciences, told Yicai Global.

Due to insurmountable constraints of the Yangtze River and other reasons, exchanges of personnel and elements between the two shores of the Yangtze River proved to be highly inconvenient in the past, resulting in the differences in the economic development of South Jiangsu, and Central and North Jiangsu, Wang said. High-speed rail network construction will provide the necessary ground for economic integration in these areas.

Chongming tunnel-bridge complex has provision for some sort of railway.
Plus, the Shanghai–Nantong Railway and the Lianyungang–Zhenjiang railway is under construction with both featuring new crossings on the Yangtze. I agree there needs to be additional rail crossings for pairs such as Jiangyin/Jingjiang and Yangzhong/Gaogang.

China’s First Local Government-Controlled HSR to Enter Operations Next Year

https://www.yicaiglobal.com/news/chi...ions-next-year

(Yicai Global) Aug. 3 -- China's northeastern Shandong provincial government has started work to install tracks for what will be China’s first local-government controlled high-speed railway line. The Jinan-Qingdao is expected to enter operation in 2018, reports the local Qilu Evening News.

The local government started track-laying four months ahead of schedule, with construction set to be completed by the end of December, the report said.

Once operational, the train line, with a total length of 307.9 kilometers, will facilitate a two-hour commute time between two of Shandong's major cities, the provincial capital Jinan and the key port city of Qingdao.

The local government provided 80 percent of total funding needed for the project, while China Railway Group Ltd. contributed the remaining 20 percent.

Construction began at the end of 2015, with work carried out by companies including China Railway, China Railway Construction Corp Ltd. and China State Construction Engineering Corp Ltd.

Inner Mongolia high speed line opens

http://www.railwaygazette.com/news/s...ine-opens.html

CHINA: Revenue services on the 126 km Hohhot – Ulanqab section of the future Hohhot – Zhangjiakou high speed line in Inner Mongolia began on August 3. Trial running had begun on June 29.

Construction of the 287 km Hohhot –Zhangjiakou line started in April 2014, and revenue services on the whole route are expected to start in March 2018. The alignment is designed for trains running at up to 250 km/h, and now offers a Hohhot – Ulanqab journey time of 39 min, down from 56 min on the older line which had a maximum operating speed of 160 km/h.

A 174 km line between Beijing Bei and Zhangjiakou is scheduled to be opened in 2019, completing a high speed corridor from Beijing to Hohhot which would cut journey times from more than 9 h to around 3 h.

126 km Ulanqab-Hohhot in 39 minutes it is an average of 194 km/h, ie: top speed of 250 km/h.

The remainder of the line from Ulanqab to Zhangjiakou in neighbouring Hebei province is due to open in 2018.

The fastest trains Jining-Hohhot seem to be
  1. Z183 - 68 minutes
  2. D6773 - 70 minutes
  3. D6771 - 71 minutes
  4. D6769 - 77 minutes

Well, in the media say 39 minutes, and in these webs
http://www.chinatrainguide.com/stntostn.php
http://english.ctrip.com/trains/

also:

39 m D6961
40 m D6962
46 m D6963
47 m D6964
39 m D6965
40 m D6966

Z trains run at 160 km/h.

They appear when looking for Jining-Hohhot, although in the name of station it puts "null" instead of Jining.

Maybe the new station is called "Ulanqab" and still have not changed the name on the webs.

All in all this project is amazingly impressive.
Just like others said here, HSR is a very mature technology. Leading companies involved in this business for decades sold out their know how for good money, hoping they'd stay ahead of the curve. Because of the whole dimension of the HSR program in China the Chinese could afford to raise a whole new industry branch around it, first producing for those established companies, than copying their designs on their own and nowadays they are making the step towards own developments, becoming proper competitors in the market.

Of course, it helped that NIMBYs don't stand much chance in China and that there is also no ideological opposition against HSR like in the US, where some see the communist devil in public transportation of any kind.

A lot of the technology is refined from foreign companies who had to operate in China under a JV / partnership, so some technology transfer took place.
