Learning Investment Basics to Start Building Wealth

Why Investing Is Necessary Now
Japan's ordinary savings interest rate has hovered around 0.001% for years. Depositing one million yen yields only 10 yen in annual interest. Meanwhile, Japan's inflation rate has recently exceeded 2%, meaning savings alone cause your real asset value to gradually erode.
Investing is a mechanism for "putting your money to work." While it involves risk, it offers higher expected returns than savings over the long term. The key is to acquire fundamental knowledge and understand your risk tolerance before you begin investing.
Fundamental Investment Concepts
The Relationship Between Risk and Return
For example, in the investment world, risk and return are two sides of the same coin. Investment products with higher expected returns also carry greater price volatility risk. Savings offer principal protection but virtually zero returns, while stocks offer high potential returns but carry the risk of losing principal.
The Importance of Diversification
The saying "Don't put all your eggs in one basket" succinctly captures a fundamental investment principle. Concentrating investments in specific stocks or asset classes means suffering significant losses if their value declines. Diversifying across multiple asset classes such as stocks, bonds, and real estate helps mitigate risk.
The Power of Compound Interest
Compound interest, reportedly called "mankind's greatest invention" by Einstein, is an investor's greatest ally. Investing one million yen at 5% annual return grows to approximately 1.63 million yen after 10 years, 2.65 million yen after 20 years, and 4.32 million yen after 30 years. Time is the key to wealth building. Studying the fundamentals through an investment primer makes it easier to put theory into practice.
Recommended Investment Systems for Beginners
Tsumitate NISA
For instance, tsumitate NISA is a system where investment gains on up to 1.2 million yen annually are tax-exempt. Normally, investment profits are taxed at approximately 20%, but this is waived in NISA accounts. Eligible products are limited to investment trusts carefully selected by the Financial Services Agency, making it relatively safe for beginners.
iDeCo (Individual Defined Contribution Pension)
iDeCo is a system specialized for retirement fund building, offering the significant tax advantage of full income deduction for contributions. However, funds generally cannot be withdrawn until age 60, so it should be funded with surplus money.
Which Should You Start With
If you prioritize liquidity, Tsumitate NISA is suitable; if you want to maximize tax benefits, iDeCo is the better choice. Using both simultaneously is also possible. A common approach is to first get comfortable with investing through Tsumitate NISA, then add iDeCo when you have more financial room.
Mindset for Avoiding Investment Mistakes
Don't React to Short-Term Price Movements
Stock markets fluctuate daily. Major downturns like the Lehman shock or COVID crash can occur. However, historical data shows that markets have recovered and continued growing over the long term. Panic selling during short-term declines is what leads to the greatest losses.
Secure Emergency Funds Before Starting
Money allocated for investing should be limited to surplus funds you won't need in the near future. A sound approach is to secure three to six months of living expenses as emergency funds, then invest amounts beyond that. A practical guide to asset management can also serve as a helpful reference.
How to Get Started
Opening a brokerage account can be completed online, with trading available as early as the next business day. Online brokerages offer low fees and allow starting with small amounts, making them ideal for beginners. Start with monthly investments of around 10,000 yen, and gradually increase the amount as you become more comfortable. (Related books may also help)
For investment targets, global equity index funds are widely recommended for beginners. A single fund provides diversified investment across stocks worldwide, with low management costs. Since selecting individual stocks requires knowledge and experience, building a foundation with index investing first is advisable.
