Toreko: There are several 20% discount codes. Can I use any of them for a Japanese-yen account?
USK: Check the currency first. Fintokei’s official FAQ excludes JPY accounts from BLACKFRIDAY20. A discount percentage alone does not tell you whether the code will work for your purchase.
Codes with the same discount can have different currency and purchase conditions. We have separated terms confirmed in Fintokei’s official information from USK’s referral code and a historical checkout record, and offers listed by other code promoters.
1. Five codes and their sources
| Code / discount | Published source | Eligibility | Expiry | Unverified / notes |
|---|---|---|---|---|
| FINVUBSK 30% OFF | USK referral / Oct 27 checkout record | First purchase; JPY StartTrader 2.0 ¥1m recorded | Unverified; not a claim of indefinite validity | ¥5,500 → ¥3,850 incl. tax on Oct 27. Current validity, all-plan coverage and stacking unverified. |
| OLRSE25 25% OFF | Official campaign | JPY SwiftTrader; up to 3 uses per person | Nov 30, 2026, 23:59 JST | XP benefit: pass by Dec 15; cutoff time unstated. |
| BLACKFRIDAY20 20% OFF | Official FAQ | JPY excluded; new and existing users | Nov 29, 2026; time zone unstated | No combination with other codes. Published start dates differ. |
| TCZ20 20% OFF | TradeCZ promoter article | Listed as “all purchases”; JPY and StartTrader unverified | Listed until end of Nov 2026; exact cutoff unverified | Promoter listing, not a verified checkout result. Usage limit unknown. |
| FXCG10 10% OFF | F.X.C.G. Education listing | Repeat purchases; JPY and all-plan coverage unverified | Unknown; no end date stated | Not a claim of indefinite validity. Usage limit unknown. |
The “all purchases” wording for TCZ20 comes from its promoter. USK has not verified that the code applies to JPY accounts or every plan. Promoter information is distinct from terms established in Fintokei’s official conditions or checkout.
Fintokei Official website Before choosing a code, check the official restrictions for your plan and purchase history. Check coupon rules (Japanese) → USK referral couponFINVUBSK30% off a first purchase
FINVUBSK is USK’s referral coupon for 30% off a first purchase. Check eligible plans, current validity and the discounted total at checkout.
On October 27, 2026, a purchase screen for the JPY StartTrader 2.0 plan with a ¥1 million account showed the tax-inclusive fee reduced from ¥5,500 to ¥3,850, a ¥1,650 discount. This is a historical result for that specific plan, not a guarantee of current validity or eligibility across all plans.
SwiftTrader eligibility, combination with other codes and the expiry date are unverified. An unconfirmed expiry does not mean the code is valid indefinitely.
Review the official coupon restrictions (Japanese) →2. OLRSE25 for JPY SwiftTrader
The offer covers JPY-denominated SwiftTrader plans, called Sokko Pro in Japan. The official campaign runs from November 3 to November 30, 2026 at 23:59 JST, with 25% off and a limit of three uses per person.
- The minimum interval between reward requests is reduced from 14 days to three days. This also applies to future requests on the professional account reached after passing.
- Pass the evaluation by December 15 to receive double the XP earned on that purchase. The additional XP is awarded after eligibility is assessed.
The announcement does not state a cutoff time for December 15. The purchase deadline and the pass-by deadline for the XP benefit are separate.
Toreko: Does that mean the reward reaches my bank every three days?
USK: It is the request interval that becomes shorter. You still need to meet the conditions. It is not a promise that the money will arrive within three days.
SwiftTrader has a one-step evaluation, but its product page also specifies a 6% profit target, 2% daily loss limit, 3% overall loss limit, and a 3% profit target for each reward payment. A discount or shorter request interval alone cannot determine whether a plan suits your trading. SwiftTrader product page in Japanese

The official FAQ lists all account sizes for StartTrader, SwiftTrader, ProTrader and ProTrader Swing, while excluding JPY accounts. New and existing users are eligible. The code cannot be combined with other codes.
The stated end date is November 29, 2026, without a specified time zone. The start dates differ: the official English landing page says November 2, while the official English FAQ says October 30. We do not choose one as the definitive start date.
The phrase “all programs” on an English page should not be read as confirming eligibility for every Japan-market plan.
Check currencies and conditions in the official FAQ → Fintokei Official website BLACKFRIDAY20 excludes JPY accounts. Check eligible currencies before selecting a plan. Check Black Friday conditions → 4. TCZ20 and FXCG10 are promoter listings
Toreko: If the promoter lists the code, can I assume those conditions apply to me?
USK: We can confirm the listing, but your purchase still needs an eligibility check. Where a condition is unclear, we should leave that uncertainty visible.
TCZ20: listed as running until the end of November
A TradeCZ article dated November 3, 2026 describes a special Fintokei offer of “20% off all purchases until the end of November.”
The listing does not establish eligibility for JPY accounts or StartTrader, the number of permitted uses, or an exact cutoff time. Check the final conditions, including purchase-history restrictions, at checkout or with Fintokei.
Read the TradeCZ article (Czech) →FXCG10: 10% off repeat purchases, expiry unknown
F.X.C.G. Education lists FXCG10 as a 10% discount for repeat purchases. No end date is stated, so we classify its expiry as unknown. JPY eligibility, coverage across all plans and usage limits are also unverified. An unknown expiry does not mean the code is valid indefinitely.
Read the F.X.C.G. Education listing →We do not present either as a USK-exclusive code. These links identify the promoters’ listings; we do not claim that the codes are linked to USK’s referral account or guarantee a discount.
5. FKRMW20 remains unverified
We did not find official information or public terms from an identifiable source for FKRMW20 in this research. Its discount, eligibility and expiry are not supported by the sources available to us, so it is excluded from the five-code comparison. This does not establish that the code is invalid.
6. What to check before paying
- Choose a plan that fits your trading method.
- Check whether its account currency, plan and your purchase history qualify for the code.
- Confirm the final price after entering the code and the conditions for any extra benefits.
- Do not raise your intended fee budget just to obtain a discount or benefit.
The official FAQ says coupon use requires a MyFintokei login, and individual codes may be limited to particular plans or first purchases. Official coupon troubleshooting FAQ in Japanese
During this research, an error on the official purchase page prevented a fresh code-application test. This is separate from the historical FINVUBSK application record of October 27. If a listing differs from what you see at checkout, ask Fintokei before paying.
Toreko: So, plan and currency first. Then the coupon.
USK: Yes. Narrow it down to codes for the same purchase conditions, then compare the fee and benefits. A coupon should not make you compromise on trading rules that suit you.
If you are considering your first purchase, also read the new StartTrader conditions (Japanese). Keep past campaign records separate from current offers.
Fintokei accounts operate in a demo environment. Participation fees apply. Passing, rewards and recovery of the fee are not guaranteed.
