What's actually disappearing from your ¥100,000 transfer — 2026 cost reality across 4 corridors
"Zero fee" is not cheap. Once you include FX markup, the true cost can be 3-10× the headline fee. Based on yensend.jp's live data feed, this is what really happens to your money across PHP / VND / KRW / NPR.
You've probably seen "zero fee" or "no commission" remittance ads. Yet for ¥100,000 transfers to the Philippines, Vietnam, Korea, or Nepal, a service charging ¥1,000+ in fees often delivers MORE money to the recipient than a "zero fee" alternative. The reason is FX markup — an invisible cost that only shows up when you compare what the recipient actually receives.
1. Remittance cost has two components
The total cost of a single transfer breaks into a visible "sender fee" (e.g., ¥499, ¥1,400, ¥3,500) and an invisible "FX markup" — the gap between the mid-market rate (the publicly quoted reference rate) and the rate a provider actually offers you. On a ¥100,000 transfer, an FX markup of 0.5% costs you ¥500; 2.5% costs you ¥2,500. A provider charging zero in headline fees but pricing FX 1.5% above mid is more expensive than a provider charging ¥1,500 with FX at mid.
2. How to back out FX markup from received amount
yensend.jp records the gap between mid-market (Wise public API as our mid-market reference) and provider offer rates daily. The math: (a) compute the theoretical amount your recipient would receive at mid-market for ¥100,000, (b) compare to what each provider actually delivers, (c) the gap is the hidden FX cost. Add the headline fee and you get true total cost. yensend.jp's comparison board sorts by total cost (ascending) — never headline fee — to keep this honest.
3. PHP (Philippines) — Up to ¥3,800 difference across 7 providers
PHP is the most competitive of our four corridors, with 7 providers compared on yensend.jp. As of 2026-05-02, ¥100,000 produces between roughly 34,716 PHP (worst) and 38,720 PHP (best). That ~3,800 PHP gap (~¥9,800 equivalent) means choosing the wrong provider once a month costs you ~¥4,800 per year for the recipient — and the gap stays even with "zero fee" providers because they recover via FX markup.
4. VND (Vietnam) — FX dominates over headline fees
VND has only 4 providers in this corridor as of 2026, but the rate spread is dramatic. ¥100,000 yields between ~15.39 million VND (worst) and ~16.65 million VND (best) — a gap of ~1.24 million VND (~¥6,800 equivalent). "Zero fee" providers are not always best here because their FX margins compensate. Always compute total received amount.
5. KRW (Korea) — The traditional bank advantage no longer holds
Korea was historically a banker's corridor — SMBC, Mitsubishi UFJ. But on rate × fee combined, specialist remittance services now win. SMBC: ¥3,500 fee + 9.18 rate → ~886,069 KRW received. Wise: ¥1,313 fee + 9.37 rate → ~924,976 KRW received. ~¥4,100 equivalent gap per transfer; ~¥50,000 per year for monthly senders.
6. NPR (Nepal) — Fewer providers, wider rate spread
NPR has only 3 providers compared on yensend.jp (Wise, Instarem, Rakuten Bank). ¥100,000 yields between ~88,547 NPR (worst) and ~95,950 NPR (best). The ~7,400 NPR (~¥7,800 equivalent) gap is wider than PHP because supply-side competition is thinner. Even "zero fee" providers can lose to mid-fee competitors here. Always compare 2-3 services minimum.
7. A short checklist for finding the actually-cheapest option
(1) Don't decide on headline fee alone — check FX markup. (2) "Zero fee" is a warning signal: check the provider's offered rate vs. mid-market. (3) Multiply the gap by your monthly send count: ¥3,000 per transfer × 12 months = ¥36,000/year. (4) Compare what the recipient receives in destination currency, not what you pay in JPY. (5) Note the gap between cached display rate (often 60s-30min old) and the rate at lock-in time. Most large providers lock the rate for 30 min – several hours after submission. (6) For bank wires, check intermediary bank fees and which side pays them — often a hidden ¥1,000-3,000.
