From the front line of change, moving further forward together.

Competitiveness in space infrastructure is no longer decided by how many satellites one owns. In the first half of 2026, a rapid succession of developments—the Ministry of Defense's contract for its "Tri-Sat" satellite program, the reorganization into the Japan Aerospace Self-Defense Force, and the selection of J-LEO to carry communications autonomy—moved Japan's space infrastructure from the stage of "concept" to that of "implementation." The real question is who links the information gained from space to decisions, when, and in what order of priority. Drawing on the author's own experience operating satellite communications within the Japan Self-Defense Forces, this article examines the design of a next-generation space infrastructure that keeps national security and commercial space in mutual circulation.

Regional banks in Japan face structural challenges: shrinking local economies driven by population decline, prolonged pressure on interest margins, and declining visibility into commerce flows as payments and customer touchpoints shift to external platforms. Traditional banking models reliant on financial statements and ex-post transaction data are increasingly unable to capture real-time local dynamics or provide practical, high-value client support. One potential lever is the combination of BNPL (Buy Now, Pay Later) services and advanced data analytics. This paper examines local economic contraction and the information-infrastructure constraints facing regional banks, with particular attention to the structural problem of limited commerce-flow visibility.

In Part I, we presented the results of an estimate indicating that electricity demand in 2050 could reach 1.5 times the current level. In Part II, we focused on next-generation nuclear power as a key technology for providing the supply capacity needed to meet that demand, and examined the challenges involved in promoting it as well as possible solutions. In this final installment, we frame the coming era—when the wave of carbon neutrality (CN) investment has run its course and CN is no longer the top priority—as the "world after the end of CN momentum." We then identify the social demands the industry will face in that era and consider what kinds of strategies can spare the industry future rework.

In Part I, we presented the results of an estimate indicating that electricity demand in 2050 could reach 1.5 times the current level, and examined the power generation mix that could meet such demand. The analysis confirmed the reality that even if renewable energy and thermal power generation were utilized to their fullest extent, around 40% of total electricity demand would still remain unmet, meaning that nuclear power would inevitably have to play a substantial role. In this second installment, we summarize trends in new technologies that address the greatest challenge facing nuclear power—safety—and examine the issues surrounding the promotion of nuclear power, as well as possible measures to resolve them.
