The yield may look attractive compared with deposits, but a corporate bond carries credit risk, price fluctuation risk if sold before maturity, and liquidity risk.

This article summarizes the terms, schedule, yield, and risks to check before buying Tohoku Electric Power’s 584th bond.

This is not a recommendation to buy the bond. Before investing, confirm the prospectus, pre-contract documents, selling-company terms, tax treatment, and the issuer’s financial condition.

What Matters Most

This is a three-year domestic retail bond with a 1.89% coupon.

It may catch the eye of investors looking for a higher return than bank deposits, but it is not the same as a principal-guaranteed deposit.

Point to check	What to confirm
Coupon	Whether 1.89% is enough for the capital lock-up
Term	Whether the money can be held until June 19, 2029
Credit risk	How to assess Tohoku Electric Power’s finances and ratings
Early sale	Whether price loss is possible if rates rise or markets deteriorate
Liquidity	Whether the bond can be sold at a desired price when needed

If held to maturity, the bond is designed to redeem at par unless the issuer defaults.

But money that may be needed soon, emergency savings, or near-term spending funds should not be placed in a product that may need to be sold before maturity.

Basic Terms

According to Tohoku Electric Power’s announcement, the 584th bond is an unsecured corporate bond for individual investors.

Proceeds are planned for capital expenditures, bond redemption funds, and loans to Tohoku Electric Power Network.

Denomination	100,000 yen
Issue price	100 yen per 100 yen of face value
Redemption price	100 yen per 100 yen of face value

The 100,000 yen denomination is accessible for retail investors.

However, the risk types do not change because the ticket size is small. Corporate bonds are not covered by deposit insurance. They are investments in the issuer’s credit.

Offering Schedule

Acceptance times and allotments differ by securities company.

Mizuho Securities’ notice states that its online offering period runs from 9:00 on June 1 to 15:30 on June 18, 2026.

Because sales amounts are limited, subscriptions can close before the final date.

How To View The 1.89% Coupon

The pre-tax coupon is 1.89% per year.

Mizuho Securities’ notice shows an after-tax coupon of 1.506% per year, reflecting Japan’s 20.315% tax on interest.

For a 100,000 yen investment, simple pre-tax annual interest is 1,890 yen.

100,000 yen x 1.89% = 1,890 yen per year before tax

Actual proceeds vary depending on tax treatment, holding period, account type, and interest payment periods.

The key is not to look at coupon alone. This is a product that pays 1.89% per year in exchange for locking funds for three years and taking issuer credit risk.

If rates rise after purchase, the price may fall if sold before maturity.

Ratings Are High, But Risk Is Not Zero

The bond is rated A+ by R&I and AA by JCR.

As a domestic electric utility bond, it may be viewed as relatively high quality.

But a rating is not a guarantee of principal or interest.

The issuer’s financial condition can change because of fuel costs, electricity supply and demand, regulation, interest rates, capital investment burden, nuclear policy, and transmission/distribution policy.

The order of analysis should be:

Coupon
↓
Issuer credit quality
↓
Can the money be held to maturity?
↓
Early-sale price risk
↓
Concentration within the portfolio

This should be viewed as accepting credit risk for a higher coupon than deposits, not as “safe because it is an electric utility.”

What Is The Pari Passu Clause Among Bonds?

This bond has a pari passu clause among bonds.

In simple terms, if Tohoku Electric Power later provides collateral to other unsecured bonds, this bond would receive equivalent treatment.

This is an investor-protection clause.

However, it does not mean the bond is secured from the start. The bond is an unsecured bond.

Benefits

Benefit	Details
Clear fixed coupon	1.89% per year
Three-year term	Maturity is visible and not ultra-long
100,000 yen denomination	Accessible for individual investors

The fixed coupon makes interest income easier to estimate.

The three-year term is easier to manage than a long 10-year bond. The 100,000 yen denomination also makes it easier for individuals to try bond investing in small size.

But visible coupon does not mean no risk.

Risks To Check

Risk	Details
Credit risk	Deterioration in Tohoku Electric Power’s finances may affect principal or interest
Price fluctuation risk	Early sale price can fall due to rates or credit conditions
Liquidity risk	It may not be possible to sell at the desired price
Rate-rise risk	If rates rise after purchase, existing bond prices tend to fall
Concentration risk	Too much exposure to one issuer or sector

The most important practical risk is loss on early sale.

Even if you intend to hold to maturity, unexpected cash needs can arise. Corporate bonds do not always sell at par.

Who Might Consider It?

Potentially suitable investor	Reason
Has surplus funds not needed for three years	Easier to hold to maturity
Wants a higher coupon than deposits	Fixed 1.89% coupon is visible
Does not want stock-like volatility	Bond-oriented investment
Understands issuer credit risk	Corporate bonds depend on issuer credit

It is less suitable for:

Less suitable money	Reason
Money needed within a few months	Early sale may be required
Emergency savings	Not a principal-guaranteed deposit
Money seeking capital gains	Corporate bonds mainly provide interest income
Investors who do not want issuer analysis	Credit risk is central

Conclusion

Tohoku Electric Power’s 584th bond has simple, easy-to-understand terms: 1.89% coupon, three-year maturity, 100,000 yen denomination, and ratings of A+ by R&I and AA by JCR.

It can be seen as an option for investors seeking income above deposits.

But a corporate bond is not a deposit.

If sold before maturity, price fluctuation can occur. Credit risk and liquidity risk also remain.

The key question is not only whether 1.89% is high.

Is this money unused for three years?
↓
Can you accept Tohoku Electric Power credit risk?
↓
Can you assume no early sale?
↓
Is the exposure size appropriate within total assets?

If the answer is unclear, the coupon alone should not drive the decision.
