This article exposes how Japan’s advanced technologies have been diverted to North Korea’s nuclear and missile programs through covert networks, highlighting the dangerous consequences of public indifference and insufficient legal frameworks.

Japanese nationals affiliated with KASST have skillfully approached Japanese researchers at national universities and absorbed Japan’s advanced technologies, according to public security officials.
In June of this year, North Korea launched three short-range ballistic missiles.
All were believed to use solid fuel.
It cannot be ruled out that jet mills illegally exported by Japanese companies played some role.
Missiles using solid fuel have far greater mobility than those using liquid fuel.
They can be loaded onto trucks and launched freely at any time.
Detection becomes significantly more difficult.
If diverted into missiles aimed at Japan, this would pose a grave threat to Japan’s peace and security.
Japanese people themselves, indifferent to such threats, are ultimately drawing a bow against their own nation.
Advanced technologies developed at national universities with taxpayers’ money are being used in North Korea’s nuclear missile development.
Subsequently, the following article appeared.
Tsutomu Nishioka, Planning Committee Member of JINF and Professor at Tokyo Christian University.
On February 10, the Japanese government announced the imposition of independent sanctions against North Korea.
The sanctions included ten items: restrictions on human movement, a general ban on remittances, a ban on entry of North Korean vessels and third-country vessels that had called at North Korean ports, and expansion of asset freeze targets.
Among these, restrictions on human movement expanded the scope under which senior Chongryon officials traveling to North Korea would be denied re-entry to Japan.
Particularly noteworthy was the newly added ban on re-entry for foreign residents involved in nuclear and missile technology who traveled to North Korea.
For many years, including myself, experts have argued that university and corporate researchers affiliated with the Association of Korean Scientists and Technicians in Japan, under the direction of the Workers’ Party of Korea, have been bringing nuclear and missile technologies to North Korea, and that their travel should be stopped.
At last, this was included in the sanctions.
However, specific names of those denied re-entry were not made public.
Recently, I obtained a list of 22 individuals denied re-entry.
According to it, five were classified as “nuclear and missile engineers.”
Although the media did not report their names, JINF had already exposed three of them in a May 2009 policy proposal, and thus all five real names are listed here.
The five individuals are: ① Seo Seok-hong, ② Seo Pan-do, ③ Byeon Cheol-ho, ④ Ri Yeong-deok, ⑤ Yang Deok-cha.
① and ② are engine experts who worked at the Institute of Industrial Science of the University of Tokyo, established the Kumgang Engine Joint Venture Company in North Korea, and reportedly developed missile engines.
③ specialized in nuclear engineering at Kyoto University and currently serves as an associate professor at the Kyoto University Research Reactor Institute.
Advanced technologies developed at national universities with taxpayers’ money are being used in North Korea’s nuclear missile development.
Punish the transfer of dual-use technologies.
All five individuals are members of KASST.
KASST promotes the slogan “Science has no borders, but scientists have a homeland,” while exporting large volumes of advanced technologies from Japan’s national universities to support North Korea’s military.
JINF has already argued that comprehensive sanctions stopping goods, money, and people should be implemented, and that all travel by resident Koreans to North Korea should be banned in principle to halt technology leakage.
Technicians other than these five are still able to travel freely between Japan and North Korea.
The re-entry ban should be expanded to all resident Koreans and implemented immediately.
Furthermore, transferring nuclear and missile technologies to hostile states like North Korea is not illegal under current law, making it impossible to arrest the five on those grounds.
A new legal framework to crack down on such acts must be established urgently.
This article also proves the correctness of my argument regarding why opposition parties filled with modern-day Hotsumi Ozaki figures and organizations such as the Asahi Shimbun persistently oppose conspiracy legislation.
