What does Japan actually supply at each layer?
| Layer | Component | JP supplier | Evidence | Status |
|---|---|---|---|---|
| 1 — Raw material | Carbon fiber composites | Toray Industries (3402.T) | Nikkei Asia 2016: $2-3B multi-year deal for rocket body composites | CONFIRMED |
| 1 — Raw material | Carbon fiber alternative | Teijin (3401.T) | No public SpaceX link | NOT a JP supplier |
| 1 — Raw material | Specialty alloys / Inconel | Daido Steel (5471.T), JSW (5631.T) | No public SpaceX link (Daido in EV theme, JSW in nuclear/defense) | NOT confirmed |
| 2 — Subsystem | Raptor engine components | None publicly named | IHI (7013) does NOT supply Raptor; serves H3/JAXA only | NOT a JP supplier |
| 2 — Subsystem | Avionics / star trackers | None publicly named | Hamamatsu (6965 in light) supplies non-SpaceX scientific clients | NOT a JP supplier |
| 2 — Subsystem | Satellite components | None publicly named | NEC (6701) / MELCO (6503) serve JAXA, not SpaceX | NOT JP suppliers |
| 2 — Subsystem | Solar cells (silicon, Starlink) | None publicly named | Sharp (6753), Solar Frontier — no public SpaceX deal | NOT confirmed |
| 4 — End-product customer | Starlink satellite-to-cell | KDDI (9433.T) — au Starlink Direct | KDDI press release 2025-04-16 — Japan's first D2C satellite service | CONFIRMED (downstream) |
| 4 — End-product customer | Starlink satellite-to-cell | NTT Docomo (parent NTT 9432.T) — docomo Starlink Direct | Advanced Television 2025-10-27 + 2026-04-06 | CONFIRMED — but NTT already in light theme; cross-tag |
| 4 — End-product customer | Starlink satellite-to-cell | SoftBank (9434.T) | SoftBank announcement 2026-04 | CONFIRMED — but SoftBank already in dcpower theme |
Net result: out of all the noise, only 2 stocks have a CONFIRMED direct SpaceX link new to the space theme:
- Toray Industries (3402.T) — upstream supplier (CARBON FIBER)
- KDDI Corporation (9433.T) — downstream customer (STARLINK D2C)
Two new stocks added to space_companies.json
Toray Industries (3402.T) — HIGH conviction
| Layer | Materials / Carbon Fiber (upstream supplier) |
| Market cap | ¥1.69T |
| PE TTM / Fwd | 22.0× / 17.3× |
| Dividend yield | 2.23% |
| 52-week return | +18% (NO SpaceX halo priced in) |
| Share price (2026-05-14) | ¥1,163.5 |
| SpaceX link | CONFIRMED — multi-year carbon fiber supply deal announced 2016-08-17 |
Thesis (short): The only Japanese-listed company with a publicly confirmed direct SpaceX supply relationship. With SpaceX IPO targeting June 2026 at $1.75T-$2T valuation and Starship scale-up driving new composite demand, Toray sits at the upstream material choke. PE 22× is cheap by AI photonics standards (Fujikura 88, Furukawa 65) — and +18% 52w means the SpaceX IPO halo is NOT priced in yet. The contrarian buy ahead of the S-1 filing.
Confirmed supply chain:
- **SpaceX** — carbon fiber for rocket/space-vehicle bodies (TORAYCA series); $2-3B multi-year deal per Nikkei Asia 2016
- **Boeing / Airbus** — aerospace-grade carbon fiber for 777X, 787, A350; recent long-term agreement with Syensqo per CompositesWorld
- Defense / military aerospace — industry-standard supplier
Key dates:
- 2026-05-18 to 05-22: SpaceX public S-1 filing window — watch for material-supplier disclosures
- 2026-06-08: Roadshow begins
- 2026-06-30: Estimated SpaceX IPO pricing
KDDI Corporation (9433.T) — MEDIUM conviction
| Layer | Downstream / Starlink customer (au Starlink Direct) |
| Market cap | ¥10.07T |
| PE TTM / Fwd | 14.4× / 12.9× |
| Dividend yield | 3.31% |
| 52-week return | +3.7% (essentially unpriced) |
| Share price (2026-05-14) | ¥2,645.5 |
| SpaceX link | CONFIRMED — au Starlink Direct (first JP direct-to-cell satellite service) April 2025 |
Thesis (short): First Japanese telco to deploy a direct-to-cell satellite service using SpaceX Starlink — covers all of Japan including mountainous regions and disaster zones via Starlink LEO constellation. With SpaceX IPO June 2026 spotlighting Starlink as the revenue engine inside SpaceX, KDDI's Starlink partnership becomes a strategic differentiator vs Rakuten (AST SpaceMobile). Downstream customer link (KDDI pays Starlink wholesale) is a different supply-chain direction than upstream supplier (Toray sells to SpaceX) but equally legitimate exposure.
Confirmed supply chain:
- **SpaceX Starlink** (KDDI = CUSTOMER) — Starlink LEO satellite capacity for au Starlink Direct D2C service; nationwide JP coverage per KDDI Newsroom and RCRWireless 2025-04-16
- Consumer mobile users (KDDI's downstream) — au brand, satellite-direct coverage
HALO ONLY — the 8 existing space stocks (AP03 concept-stock flag)
The existing `space_companies.json` has 8 stocks. NONE of them has a publicly confirmed direct SpaceX supplier or customer relationship. Their fundamental exposure is to JAXA, Japan Space Strategy Fund (¥1T over 10 years cabinet-approved 2023), and domestic JP space programs.
If these stocks rally on the SpaceX IPO buzz, that's AP03 concept-stock behavior — bid on the wrong story.
| Ticker | Name | JAXA / JP exposure | SpaceX link |
|---|---|---|---|
| 290A.T | Synspective | SAR satellites — JAXA fund recipient | None |
| 464A.T | QPS Holdings (iQPS) | SAR satellites — JAXA fund recipient | None |
| 6701.T | NEC Corporation | JAXA satellite primes + IOWN | None (NEC is Open APN customer of NTT, not SpaceX) |
| 186A.T | Astroscale Holdings | Debris removal — JAXA + ESA contracts | None |
| 9348.T | ispace, inc. | Lunar landers — JAXA + commercial | None |
| 402A.T | Axelspace Holdings | Earth observation small-sat constellations | None |
| 6503.T | Mitsubishi Electric | H3 rocket payload, satellite buses | None (MELCO already cross-tagged in light theme for InP EML) |
| 7013.T | IHI Corporation | H3 rocket engines (LE-9) | None (IHI is JAXA supplier, not SpaceX) |
Mitigation: Don't size these stocks based on SpaceX IPO narrative. They're legitimate JP-space plays based on the ¥1T Japan Space Strategy Fund and JAXA programs — but the rerating from SpaceX IPO is sentiment-only.
Anti-Pattern Check (per research_philosophy.md)
AP01 — Peak Earnings Trap
Toray (3402): +18% 52w, PE 22 — pre-rally, no peak risk
KDDI (9433): +3.7% 52w, PE 14 — pre-rally, no peak risk
8 halo names: stocks like 290A Synspective, 464A QPS, 186A Astroscale have already rallied 50-150% 52w on JAXA fund + space theme buzz — AP01 flag for those names as SpaceX IPO catalyst piles on top
AP02 — Capacity Hangover
No JP capacity over-build flagged. Toray's carbon fiber lines are tight; SpaceX additional demand absorbs capacity. KDDI's satellite-direct doesn't require capex on KDDI's side.
AP03 — Concept Stock Trap — CRITICAL FLAG
This is the MOST IMPORTANT check for the SpaceX IPO catalyst.
The 8 existing space stocks are at moderate-to-high risk of AP03 concept-stock behavior if retail / theme flows bid them on SpaceX narrative. The most exposed:
- 9348.T ispace — already +50%+ on lunar lander narrative; if bid further on SpaceX IPO halo, peak-rally with no fundamental SpaceX link
- 186A.T Astroscale — debris removal narrative; not a SpaceX supplier or customer
- 402A.T Axelspace — Earth-observation constellation; competitive with Planet/Starlink at the EO layer but no SpaceX supply link
Mitigation: the markdown export explicitly labels each existing stock as JAXA-oriented, not SpaceX-oriented.
Trade construction — confirmed vs halo allocation
| Bucket | Allocation | Picks | Rationale |
|---|---|---|---|
| CONFIRMED upstream | 12% | Toray 3402 | $2-3B multi-year SpaceX carbon fiber deal; PE 22 / +18% 52w = cheap pre-catalyst |
| CONFIRMED downstream | 8% | KDDI 9433 | au Starlink Direct (first JP D2C); PE 14 + 3.3% yield = stable defensive carrier with embedded SpaceX exposure |
| Other JP telcos with Starlink exposure | — | NTT 9432 (Docomo Starlink Direct — already in light theme), SoftBank 9434 (already in dcpower) | Cross-tagged but not re-added to space |
| HALO core space (JAXA-funded) | 5% each, max 15% combined | 290A Synspective, 464A QPS Holdings | JP space sector exposure ex-SpaceX |
| HALO satellite/lunar narrative | 0-3% each | 9348 ispace, 186A Astroscale, 402A Axelspace | Speculative; size small; don't double-up on SpaceX halo |
| Anchor diversifieds (existing in space theme) | 5% each | 6701 NEC, 6503 MELCO, 7013 IHI | Conglomerate JP space-program exposure; not SpaceX-linked |
| AVOID | 0% | Companies bid as "SpaceX supplier" without on-chain evidence | Watch trade press for false "Toray2" claims |
Total HIGH-CONVICTION SpaceX-IPO-exposure portfolio: 20% allocated to confirmed (Toray + KDDI), 15% max to halo space basket, rest to anchors or cash.
Risks to this thesis
- Toray deal disclosure: the 2016 Nikkei article is the most recent public confirmation. If SpaceX has since renegotiated to a different carbon fiber supplier (Hexcel US), the thesis weakens. SpaceX S-1 should disclose material-supplier concentration risk — watch for it.
- IPO postponement: SpaceX IPO could be pulled for market conditions, regulatory pushback, or Elon Musk public-company aversion. If pulled, halo deflates immediately; Toray's underlying business continues but the catalyst window closes.
- KDDI Starlink economics: wholesale rate not disclosed. If post-IPO Starlink raises rates, KDDI margins compress.
- Better-priced JP space play emerging: if a smaller JP supplier (e.g., specialty alloy maker) gets named in the S-1, that becomes the primary trade.
SpaceX IPO S-1 monitoring checklist (2026-05-18 to 05-22 publication window)
| Item | What to look for | Stock impact if found |
|---|---|---|
| Risk factors — supplier concentration | Named supplier disclosures (esp. "carbon fiber composites") | Toray 3402 explicit naming = UPGRADE to STRONG conviction |
| Risk factors — Starlink revenue concentration | Carrier wholesale breakdown by country/customer | KDDI / SoftBank / Docomo named = UPGRADE; if NOT named = neutral |
| Business overview — Starship | Carbon-fiber-bodied components for heat shields, payload fairings | Confirms Toray ongoing relationship |
| Use of proceeds | Capex for Starlink V3 expansion | Justifies broader space ecosystem rerating, neutral to JP names |
| Customer concentration | Top customers (NASA, USSF, etc.) | Strengthens defense theme — IHI 7013 indirect exposure remains weak |
| MD&A — geographic | Japan revenue from Starlink | Confirms KDDI Starlink revenue contribution to SpaceX |
