Yup, Japan's among the world's most advanced nations in pretty much all sectors.

Japan can do anything anyone else can, and more than most other nations.
No. That's a "Japanese" turbofan engine (IHI XF5-1) licensed from the United States' GE.
Regarding rocketry, the indigenous Japanese model was discontinued due to frequent failure. The "Japanese" rocket used today is a derivative of American technology.

Why does alleged Japanese XF-7-10 engine use GE cowl opening systems?
Has it occurred to you that the alleged Japanese XF-7-10 engine is actually an American GE engine derivative? And thus it is compatible with the GE cowl opening systems?
If the XF-7-10 was truly Japanese, it would use indigenous Japanese cowl opening systems.

IHI is responsible for the XF-5 and XF-7-10 engines. However, IHI is a small $13 billion company whose primary business is as a shipyard.
IHI is merely a Boeing subcontractor. The United States has generously allowed the Japanese to build an American engine under license and call it "Japanese." It is most certainly not Japanese. The technologies are all American.

IHI Corporation - Wikipedia, the free encyclopedia
"IHI Corporation (株式会社IHI Kabushiki-gaisha IHI?), formerly known as Ishikawajima-Harima Heavy Industries Co., Ltd. (石川島播磨重工業株式会社 Ishikawajima Harima Jūkōgyō Kabushiki-gaisha?), is a Japanese company which produces ships, aero-engines, turbochargers for automobiles, industrial machines, power station boilers and other facilities, suspension bridges and other transport-related machinery.
IHI turbochargers, commonly used in passenger automobiles, are manufactured by Ishikawajima-Harima.
Boeing and General Electric Aviation have subcontracted parts of several models of jumbo jet aircraft out to IHI, as well as Kawasaki Heavy Industries, Mitsubishi Heavy Industries, and Fuji Heavy Industries. It is listed in Tokyo Stock Exchange section 1.
History
1853 - establishment of Ishikawajima Shipyard
1889 - incorporation of Ishikawajima Shipyard as Ishikawajima Shipbuilding & Engineering Co., Ltd.
1907 - establishment of Harima Dock Co., Ltd.
1929 - spinoff of Harima's automobile section as Ishikawajima Automotive Works (later Isuzu through a series of mergers)
1960 - establishment of Ishikawajima-Harima Heavy Industries Co., Ltd. through a merger of Ishikawajima and Harima
IHI and Sumitomo Heavy Industries merged a warship business in 1995 and established Marine United Ltd. The Uraga Dock Company was the origin in the shipbuilding of Sumitomo Heavy Industries. It was made by Enomoto Takeaki. However, Sumitomo Heavy Industries moved Uraga Dock to Yokosuka in 2003. IHI moved a shipbuilding section to Marine United in 2002 and changed name to IHI Marine United Ltd. IHI Marine United became the subsidiary of IHI in 2006.
2000 - purchased Nissan Motor’s Aerospace and Defense Divisions and established IHI Aerospace Co., Ltd.
2007 - name changed to IHI Corporation
2012 - merged its ship building unit, Marine United Inc., with Universal Shipbuilding Corp. of JFE Holdings after discussion started in April 2008[1]"

"V2500 turbofan engine
This medium-size engine was developed in an international collaborative project involving Japan, U.S.A., U.K. and Germany, and has been installed on aircraft with 120 to 180 passenger seats such as the Airbus A319, A320, A321, and Boeing MD-90.
For this best-selling engine with over 5,000 orders to date, IHI supplies fan modules and low-pressure shafts, and also focuses its efforts on maintenance work.

GE90 turbofan engine
This is an engine with the world's largest engine thrust installed in Boeing 777s. The largest model of this series has a diameter of over 3 m.
This engine was jointly developed by a manufacturer group consisting of General Electric （GE） U.S.A. and IHI.
Trent turbofan engine
IHI supplies mainly the turboshaft and low- and medium-pressure turbine parts for this large-scale engine developed by the Rolls-Royce plc.
F110 turbofan engine
This engine powers the F-2 support fighter, which was jointly developed by the United States and Japan.IHI has conducted mass production as the prime contractor through a license with General Electric (GE) of U.S.A.
T700 turboshaft engine
This engine powers the Ministry of Defense anti-submarine, rescue, and multi-purpose helicopters. It is turning the rotors by converting the jet blast to rotative power. IHI also has conducted mass production through a license with General Electric （GE） of U.S.A."

I missed one from IHI's website. Even for a small turbofan engine, IHI needs American help.

CF34 turbofan engine
This is a small-size engine for the world's regional jet planes with seating capacity of about 70 to 100. This engine was jointly developed and being produced by a manufacturer group consisting of General Electric （GE） U.S.A. and IHI."

Give me a break. Japan's IHI is a "screwdriver" company. IHI licenses technology from Western countries and manufactures parts that were designed by Western aerospace multinationals.
Japan's IHI has just announced the news that it's manufacturing Pratt & Whitney parts for the American F-35. IHI cannot design and build a modern turbofan engine on its own (with the possible exception of a trainer and I'm not sure how much transfer of technology was involved there).
Read the following press release carefully. It describes the difference between American Pratt & Whitney and Japan's IHI.
Pratt & Whitney is "a world leader in the design and manufacture" of aircraft engines. IHI is a mere sub-"contractor" of aircraft engines in "international collaborative projects." This means the international partner brings the world-class technology and IHI performs some of the sub-contracting work.
Pratt & Whitney and IHI Sign Contract for Japan F135 Engines and Industrial... -- TOKYO, Nov. 6, 2013 /PRNewswire/ --
"
Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, auxiliary and ground power units and small turbojet propulsion products. United Technologies Corporation, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and building industries.

IHI is the primary contractor and manufacturer for the aircraft engines used by the Japan Ministry of Defense, and participates in international collaborative projects that develop and supply various market segments, from super large to small engines for civilian aircraft."

I will trace the lineage of IHI's XF-5 engine.
From his own citation, we know the XF-5 engine is derived from the XF-7 used on the Kawasaki XP-1 maritime patrol aircraft. I have included my own citation as a second source.
Japan's new fighter takes | Aviation International News
"Power comes from two
IHI XF5-1 afterburning engines, derived from the same core as that of the XF7 high-bypass-ratio turbofan used in the Kawasaki XP-1 maritime patroller."
From Global Security, we know that the XF-7 is based on General Electric's CF34-8 engine. The only minor difference is a larger diameter for the engine and nacelle.
P-X Maritime Patrol Follow-on | Global Security
"
This all-new Japanese engine is similar in most respects to the General Electric CF34-8, in which IHI and KHI have a production share. The big difference is that the US engine has a bypass ratio in the region of 5, while that of the Japanese engine is 8. This ought to make it quite quiet and fuel efficient, and was
achieved with only a modest increase in engine and nacelle diameter. On published figures, the Japanese engine is also significantly shorter."
General Electric CF34-8 engine ---> minor enlargement of engine and nacelle diameter ---> Japan's IHI XF-7 engine ---> some more minor tweaks ---> Japan's IHI XF-5 engine (which has the same core as the XF-7 engine, see citation above by Aviation International News Online).
In conclusion, Japan's IHI XF-5 engine is merely a General Electric CF34-8 engine variant. The core technologies all came from General Electric.

"IHI Named a Major Participant in the GE CF34-8C Engine Program
April 28, 1995
LYNN, Massachusetts - GE Aircraft Engines and Ishikawajima-Harima Heavy Industries (IHI) of Japan have signed a Memorandum Of Understanding whereby IHI is responsible for the design and manufacture of approximately 25 to 30 percent of the CF34-8C turbofan engine."
Who designed the other 75% of the engine? General Electric.
Since GE designed 75% and IHI did 25%, who do you think deserves the credit for the engine?
----------
Japan's IHI has been licensing GE turbofan engine technology for 56 years.
Nothing has changed. Japan's IHI is still building engines based on GE technology.
