Slide 2 / Why

Why investing affiliate income via NISA
is "offensive wealth building"

Two points: peace of mind × aligned time horizons
  • Reason 1
    Peace of mindYour day-job salary is living infrastructure — there's resistance to reducing it. Side-income is "extra you wouldn't miss," so it's easy to steer into risk assets.
  • Reason 2
    Aligned time horizonsGrowing an affiliate business over 5-10 years aligns perfectly with long-term NISA investing. Both compound and grow.
Slide 3 / Allocation

The ideal way to allocate

Slide 8 / No-go

The 3 no-go cases
for NISA investing

Zero emergency fund · all-in investing · leverage concentration
  • NG1
    NISA with zero emergency fundTapping it during an income drop wipes out the long-term benefit. Keep six months of living expenses in an ordinary deposit.
  • NG2
    Routing all affiliate income into investingWithout reinvesting in the business, your core (affiliate) income stops growing.
  • NG3
    Concentrating in leveraged productsEven in NISA, high-risk concentration runs counter to the spirit of long-term contributing.

📋 In review

① Why offensive: peace of mind + aligned horizons
② Allocation: living 30 / reinvest 30 / NISA 30 / reserve 10
③ Conservative: all-world 60 + bonds 30
④ Standard: all-world 50 + U.S. 30 + high-dividend 15
⑤ Aggressive: U.S. 40 + emerging 20 + sector 20 + individual 20
⑥ Simulation: ¥100K/mo × 20 yrs = ~¥41.10M (estimate)
✅ Bottom line: Affiliate income is an "offensive asset" that pairs well with NISA investing. Even starting at 30% of ¥100K/month (¥30K), over 20 years a ¥12M principal grows to about ¥15.53M (estimate at 5%/yr). Pick the one of three patterns that fits your risk tolerance, and leverage the strength of variable income × flexible contributing.
