## PHASE 2: SSW Type 2 (Years 6-15) — Realistic Projection

### Assumptions for SSW-2 Transition
- Successfully upgraded to SSW-2 after passing advanced exam + 2–3 yrs supervisory experience

### Monthly Expenses for SSW-2 (Low Spending)

SSW-2 workers typically move to better housing and have family considerations, but **maintaining minimal spending:**

**Housing:**
- No longer in company dorm; renting independently

### SSW-2 Monthly Savings

**Net Income - Expenses = Savings**

¥270,000 - ¥142,000 = **¥128,000/month**

In Rupiah: **Rp 13,754,460/month**

**Annual Savings (SSW-2):**
- ¥128,000 × 12 = **¥1,536,000/year**

## Reality Check: Low Spending Challenges

⚠️ **Important Notes:**

1. **Dining & Social Costs:** Many SSW-1 workers report feeling unable to save much because the ¥140,000–¥160,000 take-home feels inadequate when not subsidized. This projection assumes *strict* discipline.

2. **Housing Reality:** SSW-1 gets company housing support, but the typical setup charges ¥20,000–¥30,000 monthly support costs paid by the employer (not the worker). This projection already accounts for that.

3. **Unexpected Expenses:** Medical, visa renewal, plane tickets home, emergency repairs—not included.

4. **Inflation:** Japan's inflation is low (~2%/year), so these figures hold reasonably.

5. **Exchange Rate Risk:** Rupiah fluctuates vs. Yen. A weaker Rupiah means your savings buy less in IDR terms.

## Alternative Scenarios

### If You Reach Higher Salary in SSW-2 (¥400,000/month gross):
- Net: ¥310,000 after taxes
- Expenses (same): ¥142,000
- **Monthly savings: ¥168,000** (vs. ¥128,000)
- **10-year SSW-2 total: ¥20,160,000** 
- **15-year grand total: ¥24,690,000 (Rp 2,652,184,500)**

### If You Add Side Income (freelance coding, tutoring, etc.):
- ~¥50,000–¥100,000/month additional
- This could realistically double or triple total savings

## Financial Stability Assessment

**Conservative 15-Year Outcome: Rp 2,137,164,600**

For context (April 2026 Indonesian prices):
- Average Jakarta rent: Rp 8–12 million/month
- Motorcycle: Rp 15–25 million
- Car down payment: Rp 50–100 million+
- University tuition: Rp 20–80 million/year

**Summary:** This ¥19.89M is meaningful capital for your Japan re-entry strategy, but **real wealth accumulation requires**:
1. Disciplined spending (as shown)
2. Possible side income during SSW years
3. Strategic investment of accumulated savings (not just sitting in bank)
4. Family financial support for the initial visa/setup costs

---

## Revised Goal: What's Realistic?

**Minimum capital for Japan self-sufficiency:**
- Initial visa/setup costs: ~¥1–2M (flights, COE, first month)
- Post-SSW security (6 months living expenses): ~¥800K–¥1M
- **Total needed: ~¥2–3M upfront**

**What you'd have after 15 years if you saved this way:** ¥19.89M

**Verdict:** You could fund an additional 10+ years *beyond SSW expiration* if transitioning to permanent residency or another visa. The money exists—it requires discipline.

---

## Next Steps

1. **Confirm eligible SSW-2 industries** for your IT skills (Manufacturing/IT sectors)
2. **Verify salary ranges** for your specific role in chosen region
3. **Plan housing location** early (cheaper prefectures vs. Tokyo)
4. **Set up automatic savings** (transfer ¥75K/month SSW-1, ¥128K/month SSW-2 to dedicated account)
5. **Research Permanent Residency pathways** for post-SSW-2 security
