A New Spaceport, a Returning Rocket, a Date on the Calendar

India Japan Kaizen — Space Industry Series, Part 6

Part 5 of this series closed the 77th International Astronautical Congress with a simple tally: Japan's ispace signed two new lunar deals that week in Antalya, with Europe's ArianeGroup and with Leonardo and Telespazio; India's ISRO deepened its own cooperation agreement with the European Space Agency; and neither signed anything with the other. It left one open question for this part to check — whether a Japanese company would step through either of the two shared facilities IN-SPACe and Tamil Nadu had already opened at Khoraj and Thoothukudi. Three weeks on, the answer there is still no. But the gap between the two countries' space sectors moved on three separate fronts since Part 5: a newly opened facility in the very district this series keeps naming turns out to have a rule that answers the "no Japanese tenant yet" question before it's even asked; the Japanese rocket this series has tracked twice over is reliably flying again after a five-month grounding; and, for the first time since this series began, there's an actual date range on the calendar for the two governments to meet.

A New Facility, With a Rule That Answers Part 5's Question for It

The Common Technical Facilities at Khoraj and Thoothukudi that Part 5 tracked are shared infrastructure, open in principle to any tenant that shows up. A different, much larger facility in the same Thoothukudi district isn't. In August, IN-SPACe opened an Expression of Interest inviting private operators to take over day-to-day running of ISRO's Small Satellite Launch Complex at Kulasekarapattinam — the ₹986-crore (about $119 million) second spaceport whose foundation Prime Minister Modi laid back in February 2024, and which the Department of Space plans to keep owning regardless of who ends up operating it. ISRO's own leadership has said the complex should be structurally complete by December 2026, inside the FY2026-27 commissioning window the government gave Parliament in 2025.

The EOI's eligibility bar is specific, and, unlike anything this series has seen so far, explicit. Applicants must be Indian-owned and controlled companies, in continuous operation for at least seven years, with a net worth of at least ₹1,000 crore and annual turnover of at least ₹2,000 crore in three of the last five years. A non-refundable ₹50,000 registration fee and an August 24 pre-EOI conference were the only other published gates. Nothing in those criteria leaves room for a foreign operator, Japanese or otherwise, to apply at all.

What the Fine Print Changes About the Question This Series Keeps Asking

Parts 4 and 5 both treated the empty tenant rosters at Khoraj and Thoothukudi's shared facility as evidence of inertia — doors standing open, with nobody from Japan having walked through yet. Kulasekarapattinam sharpens that into something more structural: this specific door was never going to open to a Japanese company, because the EOI's own eligibility criteria rule it out before any bid is even submitted. That isn't necessarily bad policy — a newly built national launch site is a different category of asset than a shared testing facility, and plenty of countries keep launch-site operation domestic by design. But it does mean the test case to watch here isn't whether a Japanese company applies; it's which Indian company does.

• Skyroot and Agnikul. The two private launch companies this series has already tracked building out integration and testing capacity in the same district are among the few private Indian space companies plausibly large enough to clear the EOI's balance-sheet bar on their own, though neither has publicly confirmed a bid.
• The money stays Indian either way. Whether a launch major, a large diversified conglomerate, or a space-tech unicorn ends up winning, the EOI guarantees the operating contract itself — unlike a tenancy at Khoraj or Thoothukudi's shared facility — goes to a company with no Japanese capital in it.

Japan's Own Rocket Is Flying Again

The H3 rocket itself has had a better three weeks than the diplomacy has. Part 5 noted in passing that Mitsubishi Heavy Industries' contract to fly ispace's Mission 3 ULTRA lunar lander depends on the same H3 that failed a December 2025 launch, when a malfunctioning second-stage engine left a navigation satellite short of its planned orbit. JAXA returned the rocket to flight on June 12, 2026, with a new H3-30 configuration — a lighter, booster-free variant flying three first-stage engines instead of the usual two-plus-boosters layout — carrying a JAXA test payload and six smallsats, including one for the French company Unseenlabs, successfully to orbit. A second consecutive successful flight since then, carrying the Cabinet Office's Michibiki No. 7 positioning satellite, has Japanese coverage describing the rocket as back to normal operations.

That matters beyond Japan's own domestic program. Both Mission 3 ULTRA and the joint ISRO-JAXA Chandrayaan-5/LUPEX lunar mission — the clearest tangible India-Japan space project this series has flagged — are now scheduled to fly on the same rocket family. A grounded H3 was a risk to both; a flying one removes it, even though neither mission is launching soon.

A Date Is Finally on the Calendar

Parts 4 and 5 both tracked diplomatic visibility accumulating between Japan and India faster than signed deals — IAC's shared stage, JAXA's president's own Antalya remarks pointed at Turkey, and two defence ministers' statements over the summer promising a fourth Japan-India 2+2 Ministerial Meeting "later this year" without naming a date. An October 28 joint statement from the two countries' defence ministries repeated that commitment, confirming the meeting is still planned for Tokyo before the year is out, building on the direction the two prime ministers gave at July's Annual Summit. Space had a line in each of the two previous 2+2 statements, in 2023 and 2024, both committing to "deepen bilateral cooperation in the field of space and cyber" without naming a specific project. A confirmed Tokyo window, even without a confirmed day, is the first concrete marker this series has had since IAC closed for whether that boilerplate finally produces something a reader of this series could point to.

What's Missing

Five months after Khoraj and Thoothukudi's shared facility opened, and three weeks after IAC closed without a single bilateral India-Japan deal, this part adds detail rather than resolution: a specific reason one Tamil Nadu facility won't see a Japanese tenant, a specific reason the H3 risk to two flagship missions has eased, and a specific window to watch for the next real test of whether Tokyo and Delhi's shared language on space turns into shared paperwork. Still missing: a confirmed day for the 2+2, a named bidder for Kulasekarapattinam, and — six parts into this series — a single signed India-Japan commercial agreement in the space sector specifically.

If you build, supply, or operate in India's or Japan's space sectors — or if you're the Indian company sizing up a bid for Kulasekarapattinam — get in touch. Watching for the right introduction at the right moment is exactly the kind of work India Japan Kaizen wants to do.

This is Part 6 of India Japan Kaizen's Space Industry Series, publishing weekly. Part 5 tracked IAC's close and the deals it produced for everyone except each other; Part 7 will check whether the fourth Japan-India 2+2 Ministerial Meeting gets an actual day, whether Kulasekarapattinam names a winning bidder, and whether the diplomacy this series has tracked for a year and a half produces its first signed India-Japan commercial deal in the space sector.
