1. Macro Theme: Japan Nuclear Restart

Status (March 2026)

15 reactors now operating out of 32 operable (~33 GW combined) NRA, EIA, WNA
TEPCO's Kashiwazaki-Kariwa Unit 6 restarted February 2026 — world's largest nuclear plant ANS, NucNet
3 more have NRA approval; 6 under review

Policy: "Reduce" → "Maximize"

7th Strategic Energy Plan (Feb 2025): Targets ~20% nuclear by FY2040 (vs 8.5% in FY2023) METI/ENECHO, IEA
Removed "reduce nuclear dependency" language from Fukushima era
60+ year reactor lifetime extensions approved — structural shift
~15 more restarts needed to reach target (one per year pace)

Data Center Demand: Underappreciated Catalyst

Japan DC power consumption projected to triple by 2034: 19 TWh → 57-66 TWh Wood Mackenzie Aug 2025
DCs = ~60% of Japan's total power demand growth through 2034
Hyperscaler capex: Amazon ¥2.26T by 2027, Google ~$690M
Tokyo power connection queues: 5-10 years

Near-Term Pipeline

3. Rankings & Recommendations

#1. Kansai Electric (9503.T) TOP PICK — HIGH CONVICTION

Thesis: Best-in-class nuclear utility at compelling valuation with income growth runway.

Nuclear fleet leader: 8 reactors operating (Mihama-3, Takahama 1-4, Ohi 3-4) — confirmed by NRA Jan 2026
Valuation: PE 6.8-7.2x, P/B 0.84-0.87 (below book), EV/EBITDA 7.5x
Quality: ROE 12.4% (above TSE 8% target), EBITDA margin 21.3%
Income: 3.4% dividend yield with 15.4% payout ratio — could 2-3x dividends
Catalysts: Reactor life extensions, Kansai DC demand, dividend increases

Scenarios: Bull (margin→15%, PE→10x) = ~35% upside | Base = 3.4% yield | Bear (quake) = ~25% down

#2. Kyushu Electric (9508.T) STRONG VALUE — HIGH CONVICTION

Thesis: Deepest-value quality utility with proven nuclear ops.

Cheapest: PE 4.9-5.0x, P/B 0.74-0.76, corrected forward PE ~6-7x
Best ROE: 16.8% — highest among all utilities
Proven: Sendai plant reliable since 2015 restart
Risk: D/E at 283% — highest leverage. Main concern.
Catalysts: Genkai restarts, TSMC/Kumamoto DC ecosystem

Scenarios: Bull (P/B→1.0x) = ~33% upside | Bear (rate shock, P/B→0.5x) = ~33% down

#3. IHI (7013.T) AEROSPACE/DEFENSE — MEDIUM CONVICTION

⚠ CRITICAL CORRECTION: Forward PE of 6.1x was a DATA ERROR caused by yfinance mishandling IHI's October 2025 7-for-1 stock split. True forward PE is ~26.7x. IHI's forward EPS is ¥117.49 (post-split), not ¥578.

At PE ~27x with ROE 23.6%, IHI is fairly valued — not a deep-value play
Aero = 34% of revenue but 77% of operating profit (22.1% margin) — this is the real driver
Nuclear is only ~25% of revenue, ~10% of profit (3.9% margin)
Currently -33% from Feb 2026 high (¥4,698→¥3,138) — potential entry point
Analyst targets: ¥3,400-¥3,730 (both neutral)

#4. Chubu Electric (9502.T) VALUE + OPTION — MEDIUM

P/B 0.66x (deepest discount), PE 8.9x, EPS growth +79.4%
Hamaoka restart = free option (market prices minimal probability)
D/E 96% is moderate; 2.7% yield

#5. TEPCO (9501.T) SPECULATIVE — LOW

Fwd PE 3.0-3.7x, P/B 0.33 — priced for permanent impairment
Binary: K-K full operations = potential 2-3x; further delays = distress continues
ROE -21.5%, no dividend, D/E 211%, current ratio 0.49
Max 5% allocation

#6. MHI (7011.T) AVOID AT CURRENT PRICE

PE 43-49x, P/B 5.1-5.8x — priced for perfection
Great franchise (sole J-PWR maker, defense, gas turbines) but no margin of safety
Any earnings miss → sharp correction. Wait for PE <30x.

4. Recommended Portfolio

Weight	Stock	Ticker	Logic
40%	Kansai Electric	9503.T	Core: best quality utility, cheapest valuation, 3.4% yield
25%	Kyushu Electric	9508.T	Core: PE 5x, P/B 0.76, highest ROE (16.8%)
15%	Chubu Electric	9502.T	Value: P/B 0.66, Hamaoka option
10%	IHI	7013.T	Growth: aero/defense pullback entry
5%	TEPCO	9501.T	Speculative: K-K binary bet
0%	MHI	7011.T	Avoid: PE 45x+ = overvalued

What the Market May Be Missing

DC demand acceleration — utility valuations don't price in power demand tripling
Kansai's dividend runway — 15% payout with 12.4% ROE = dividends could 2-3x
Kyushu corrected forward PE 6-7x — even cheaper than initially thought
Policy shift is structural — "maximize nuclear" + 60yr extensions = 15-20 year tailwind

6. Key Theme Risks

Seismic event near operating reactor → forced shutdowns, sector selloff
NRA regulatory delays — conservative post-Fukushima stance
Rising interest rates — utilities carry 127-283% D/E; BOJ tightening hurts
Public opposition — local consent required per restart
Yen strengthening — reduces fuel import costs, offsets nuclear benefit
Global nuclear incident — any international event impacts J-stocks
