Online Brokerages and Points|High Cashback on Opening an Account and Choosing for Asset Building by Economy Zone

Online brokerages: opening an account itself is a high-value points offer, and with credit-card investing cashback, economy-zone linkage, and new-NISA support, it also helps with asset building. Brokerages invest advertising money to win new account openers, and part of it comes back as a performance reward to users who open via a point site. Which brokerage you choose changes the points you accrue from monthly investing and the quality of bank/card linkage.

That said, a brokerage account is the gateway to investing, and investing carries a risk of principal loss. It isn't something to choose by cashback size alone, or to over-invest for cashback. This guide organizes, as a judgment axis for not losing out, the difference between "earned on opening" and "earned on deposit/trade", the traits of major brokerages by economy zone, choosing by credit-card investing/new NISA/bank linkage, the caution of not opening too many accounts, and how to face investment risk. For brokerage accounts, see the Brokerage Account Guide; for credit-card investing, the Credit-Card Investing Guide; and for new NISA, the New NISA Guide.

Telling "Earned on Opening" from "Earned on Deposit/Trade"

The first thing to check on an online-brokerage offer is the cashback condition. It splits broadly into two types, differing in difficulty and amount.

Offer typeCashback conditionTrait
Account-opening typeEarned on opening an accountLower hurdle
Deposit/trade typeEarned on a set deposit/tradeHigher cashback, but deposit/trade required

With "earned on opening" offers, just opening an account earns cashback. With "earned on deposit/trade" offers, a set deposit or a set number/amount of trades is the condition; the amount is higher, but you must actually move money. Always check on the offer page whether "opening alone is enough," "a deposit/trade is required," and "the type/amount of eligible trades" before routing. Absolutely avoid over-investing or making unnecessary trades to meet a deposit/trade-type condition.

Major Online Brokerages by Economy Zone

Choosing an online brokerage to match the economy zone you use (points, card, bank) makes points accrue more easily from monthly investing. Use the table below as a guide and choose one fitting your economy zone.

※ Credit-card investing rates, supported points, and account-opening offers get revised. Confirm the latest on each company's official site. SBI has the largest account base with wide credit-card investing options; Rakuten Securities is popular for Rakuten Card investing and Rakuten Bank linkage. Monex and au Kabucom are also worth choosing by economy-zone fit. Matching the economy zone where you usually accrue points is the basis.

Choose by Credit-Card Investing / New NISA / Bank Linkage

Beyond the opening cashback, choosing a brokerage on three points — credit-card investing, new NISA, and bank linkage — assuming continued use, makes long-term gains more likely.

  • Economy zone and credit-card investing: Rakuten = Rakuten Securities × Rakuten Card, au = au Kabucom, SBI line = SBI Securities. Points accrue from monthly investing. Credit-Card Investing Guide.
  • New NISA support: Confirm the tsumitate (regular) investment slot and credit-card investing support. Tax-free, you can start small. New NISA Guide.
  • Bank pairing: Brokerage × online-bank linkage gives rate perks and smooth deposits/withdrawals. Online Bank Comparison.
  • Products / fees: Confirm the handling and fees for the products you want (funds, stocks, US stocks, etc.).
⚠️

A brokerage account is the gateway to investing, and funds and stocks fluctuate with a possibility of principal loss. Don't decide a brokerage or your investing by cashback size alone. Collecting high-value opening offers is fine, but over-investing or making unnecessary trades to meet a deposit/trade-type condition defeats the purpose and can invite losses. Always invest with spare funds, within your risk tolerance. Use methods you can sustain, like starting small with the new-NISA tsumitate slot plus credit-card investing. Investment decisions are your own responsibility; understand the product's mechanism and risks, and when unsure consult a professional such as a financial planner. Keep routing/cashback to "making asset building you were going to start anyway cheaper."

Steps to Not Miss the Opening Cashback

  1. ① Check the offer's cashback conditionCheck whether it's "earned on opening" or "earned on deposit/trade" on Pointnavi. For deposit/trade type, also check the eligible trade type/amount. Not meeting the condition means zero cashback.
  2. ② Choose a brokerage fitting your economy zoneChoose to match your usual points/card/bank economy zone. Confirm credit-card investing and new-NISA support too. Brokerage Account Guide.
  3. ③ Route right before the opening formProceeding straight from an opening page open in another tab can miss cashback. Re-entering from the point site right before opening is sure.
  4. ④ Invest a little monthly via credit-card / consolidateAfter opening, accrue points via monthly credit-card investing and use the tax-free slot. Consolidate credited points into your main economy zone. Expiry Prevention Guide.

Common Mistakes and How to Avoid Them

  • "Made unnecessary trades to meet a condition for cashback": Don't over-invest for a deposit/trade-type condition. Invest with spare funds, within your risk tolerance.
  • "Chose a brokerage not fitting my economy zone and points didn't accrue from investing": Choose to match your usual economy zone. Confirm the supported credit-card investing card.
  • "Opened too many accounts and couldn't manage them": Don't open too many even for high-value offers. Narrow your main to 1–2 and keep it manageable.
  • "Thought a deposit/trade-type offer paid on opening": Misreading the condition means zero cashback. Confirm opening-type vs deposit/trade-type before routing.
  • "Forgot to route before opening, zero cashback": Make re-entering from the point site right before the opening form a habit.

What to Sort Out Before Opening an Account

A little sorting beforehand lets you choose a brokerage that fits and start asset building you can sustain.

  • Confirm your usual economy zone: Confirm the points/card/bank you use often, and choose a brokerage fitting it.
  • Decide your goal and spare funds: Decide what for and up to how much you can invest comfortably. Don't touch living funds.
  • Think about how to use new NISA: Think of a sustainable method, like starting small with the tsumitate slot. New NISA Guide.
  • Confirm the condition: Confirm whether it's "opening only" or "deposit/trade required," on the premise of not making unnecessary trades.
  • Open after routing: Finally confirm you routed through the point site right before opening. No routing means no cashback.

FAQ

Which online brokerage is best in the end?
It comes down to the economy zone you use and credit-card investing. Rakuten = Rakuten Securities × Rakuten Card, au = au Kabucom, SBI line = SBI Securities. Choose a combo where points accrue easily from monthly investing. Confirm the credit-card investing rate and new-NISA support too. Don't open too many — narrowing your main to 1–2 is recommended.
Can I get a reward for just opening an account?
It depends on the offer. With "earned on opening" offers, just opening earns cashback, but "earned on deposit/trade" offers require a set deposit or trade. Check the eligible trade type/amount on the offer page. Either way, forgetting to route means zero cashback. Don't make unnecessary trades to meet a condition.
Is it OK for beginners?
You can start small with the new-NISA tsumitate slot plus credit-card investing. But investing carries a risk of principal loss, so start with a comfortable amount. Invest with spare funds, and start after understanding the product's mechanism and risks. When unsure, consulting a professional such as a financial planner is reassuring.
How do I check the credit-card investing cashback?
Credit-card investing rates and supported cards differ by company and get revised. Confirm the latest rate and supported card on each company's official site. Check whether your economy-zone card (Rakuten Card, Mitsui Sumitomo Card, etc.) is supported and the cap. Choose by sustainability and economy-zone fit, not just the rate.
Can I open several accounts?
High-value opening offers tempt you to open many, but keep it manageable. Narrow your main to 1–2 and use credit-card investing and new NISA there — it's efficient. Opening too many makes management complex and leaves dormant accounts. Opening offers are appealing, but choose on the premise of continued use.
