For Japanese investors considering property abroad, the Bangkok–Tokyo comparison is the first analysis they should make. Here's a direct head-to-head of what 20 million yen (approximately 5M THB) buys you in each market, and which investment makes more sense for different goals.

Head-to-Head: 20M JPY (5M THB) Budget

Factor	Tokyo (23 wards)	Bangkok (central)
What you get	25 sqm studio in outer ward	45 sqm 1BR near BTS in good area

What ¥20M Buys You

City	Property	Features

Bangkok (Phra Khanong)	35 sqm 1BR, near BTS	Modern finishes, 24hr security, river views possible

The Depreciation Problem in Japan

Unlike Thailand, where well-located condos hold their value, Japanese residential property depreciates predictably. A new Tokyo condo loses 20% of its value in the first 3 years and continues declining. This depreciation is by design — Japanese buildings are regularly rebuilt to incorporate earthquake safety and modern amenity standards.

In Bangkok, a 10-year-old condo in a prime location like Thonglor or Phrom Phong has typically maintained or increased its value.

Operating Cost Comparison

Annual Cost	Tokyo (1BR condo)	Bangkok (1BR condo)
Property tax	0.7–1.4% of assessed value	0.02–0.1% of assessed value
Management fees	200,000–400,000 JPY	30,000–60,000 JPY
Repair reserve	100,000–300,000 JPY	Included in management fees
Earthquake insurance	20,000–50,000 JPY	N/A (low risk in Bangkok)
Rental management (if rented)	5–10% of rent	20–35% of rent
Total annual cost	350,000–800,000 JPY	60,000–150,000 JPY

Which Investment Wins?

Choose Bangkok If You:

Want positive cash flow (yield > costs)
Can accept Thai legal system risk (it's manageable with proper advisors)
Want lower entry prices and better space
Plan to use the property for retirement or holidays
Are comfortable with Thailand's political and economic cycles

Choose Tokyo If You:

Value Japan's legal system and property rights above all else
Need a property in Japan for residency or tax purposes
Cannot accept any non-Japan legal or currency risk
Are buying as a primary residence (not investment)
Prefer zero-foreign-quota limitations

The Hybrid Strategy

Some sophisticated Japanese investors take a hybrid approach:

Buy in Bangkok for cash flow — A 5M THB condo yielding 6% generates 300,000 THB/year (approximately 1.2M JPY)
Buy in Tokyo for capital preservation — A small Tokyo unit holds its value in yen terms
Use Bangkok rental income to offset Tokyo holding costs

This approach diversifies currency and market risk while generating positive cash flow from the Thai portion.

REVR Verdict: For pure investment returns, Bangkok wins decisively — higher yields, lower costs, and capital appreciation. Tokyo only makes sense for primary residence, tax residency, or those unwilling to invest outside Japan.
