On October 19, 1987 (Monday), the Dow Jones plunged 22.6% in one day on the New York Stock Exchange, spreading to the Tokyo market the next day. The Nikkei 225 recorded a 3,836-yen drop (14.9% decline) on October 20. The causes were complex, including chain reactions from program trading, concerns over a weak dollar, and the widening U.S. trade deficit. However, the Japanese market recovered to pre-crash levels in about six months and subsequently entered the bubble era. The key to trading is whether you can capture the sharp rebound after the crash.

On December 29, 1989, the Nikkei 225 reached its all-time high of 38,957 yen. However, a sharp decline began in the new year, and by October 1990, it had fallen below 20,000. The Bank of Japan's rate hikes (raising the official discount rate from 2.5% to 6%), real estate lending restrictions, and the outbreak of the Gulf War all contributed. It marked the end of the era when 'buying always meant profits' and the beginning of Japan's 'Lost Three Decades.' A long-term downtrend that tests your ability to sell on rallies.

In July 1997, the shift to a floating exchange rate for the Thai baht triggered a chain of currency collapses across Asia. South Korea, Indonesia, and Thailand came under IMF control. In Japan, Yamaichi Securities and Hokkaido Takushoku Bank collapsed, deepening financial system anxiety. The Nikkei fell to 12,787 yen in October 1998. Credit contraction and bad debt problems persisted, with 'credit squeeze' becoming a social issue. This tests how you navigate amid panic selling.

The spread of the internet in the late 1990s pushed IT-related stocks to abnormal highs. In March 2000, NASDAQ peaked, and substantiless '.com companies' went bankrupt one after another. The Nikkei fell from the 20,000-yen range in April 2000 to 7,607 yen by April 2003. Not just IT stocks, but the entire Japanese economy fell into a deflationary spiral. A prolonged grinding decline where timing short-covering is difficult.

On September 15, 2008, U.S. investment bank Lehman Brothers filed for bankruptcy, triggering a global financial crisis. Credit contraction originating from the subprime mortgage crisis spread to the real economy. The Nikkei plunged to 6,994 yen on October 28, 2008 (approaching post-bubble lows). Central banks worldwide coordinated rate cuts and quantitative easing, with the market bottoming in March 2009. Experience the recovery from what was called a 'once-in-a-century crisis.'

At 2:46 PM on March 11, 2011, the Great East Japan Earthquake (M9.0) struck. The tsunami and the Fukushima Daiichi nuclear disaster caused enormous damage to the Japanese economy. The Nikkei dropped about 21% in four trading days, from 10,434 yen before the quake to 8,227 yen on March 15. Nuclear and power stocks crashed while reconstruction-related stocks surged. A unique market where different sectors diverged sharply during recovery from an unpredictable natural disaster.

In June 2015, China's Shanghai Composite Index crashed 30% in three weeks. The Chinese government's ad hoc market interventions (banning short selling, halting IPOs, introducing and immediately withdrawing circuit breakers) worsened investor sentiment. In August, the devaluation of the yuan compounded the situation, accelerating risk-off sentiment worldwide. The Nikkei fell from 20,868 yen in June to 16,901 yen in September. A scenario where dependence risks on emerging economies became apparent.

In late February 2020, the global spread of COVID-19 sent markets into a panic. The Nikkei dropped 30% in about a month, from 23,386 yen on February 21 to 16,358 yen on March 19. Emergency rate cuts, fiscal stimulus, and the Fed's unlimited quantitative easing triggered a sharp rebound. By year-end, it had recovered to the 27,000-yen range in a historic V-shaped recovery. Tests your timing in catching a 'falling knife' and riding the monetary easing wave.

On August 5, 2024, the Nikkei recorded a 4,451-yen drop (12.4% decline), surpassing the 1987 Black Monday as the largest single-day decline in history. The Bank of Japan's rate hike (0% to 0.25%) drove yen appreciation, combined with U.S. recession fears and escalating Middle East tensions. The following day, August 6, saw a record 3,217-yen gain, generating extreme volatility. A market where historic price movements were compressed into just a few days.

In 2025, President Trump enacted reciprocal tariff policies, imposing tariffs of up to 145% on China and 24% on Japan, causing global supply chain disruptions and escalating trade wars. Concerns about deteriorating performance spread, centered on export companies such as automakers and semiconductor firms, and the Nikkei fell sharply. An opaque market swayed by retaliatory tariffs and negotiations between nations. Tests your trading decisions when political risk dominates the market.

The Bank of Japan implemented significant rate cuts (5% to 2.5%) as a countermeasure against the yen appreciation recession following the 1985 Plaza Accord. Excess liquidity flowed into stock and real estate markets, and the Nikkei rose roughly threefold from the 13,000-yen range in 1986 to 38,957 yen at the end of 1989. The NTT listing frenzy (1987), the financial engineering boom, and the land price myth overheated. Experience the historic bubble market dominated by the optimism that 'buying stocks always pays off.' *Due to older data, volume data may be unavailable and some candlesticks may only show closing prices.

Following the inauguration of the Abe administration in December 2012, Abenomics launched with its 'three arrows' of aggressive monetary easing, flexible fiscal policy, and growth strategy. The Kuroda Bazooka (unprecedented easing) in April 2013 accelerated yen depreciation and stock market gains. The Nikkei rose about 2.4 times from the 8,600-yen range in November 2012 to 20,868 yen in June 2015. A strong uptrend led by export companies benefiting from yen weakness. Tests your ability to buy on dips.

From the COVID crash bottom (16,358 yen in March 2020), a strong recovery rally unfolded against a backdrop of global monetary easing and fiscal stimulus. Vaccine development hopes, the surge in DX-related stocks from stay-at-home consumption, and Warren Buffett's announcement of Japanese stock investments provided additional tailwinds. The Nikkei recovered to 30,000 yen in February 2021 for the first time in 30 years. An uptrend that tests your ability to discern the transition from a 'liquidity-driven rally' to an 'earnings-driven rally.'

On February 22, 2024, the Nikkei reached 39,098 yen, surpassing the December 29, 1989 record of 38,957 yen for the first time in 34 years and 2 months.

Although the market rebounded from the Lehman shock crash, a strong recovery never materialized, and the Nikkei traded in an 8,000-11,000 yen range for an extended period. Negative factors persisted, including the European debt crisis (Greece, Spain, etc.), the Great East Japan Earthquake, and extreme yen appreciation (75 yen per dollar). The directionless market continued for about three years until Abenomics launched at the end of 2012. A scenario where mean-reversion strategies at range boundaries are effective, while trend-following approaches tend to generate more stop-losses.

On January 29, 2016, the Bank of Japan announced an unexpected negative interest rate policy. Stocks initially rose and the yen weakened, but concerns about deteriorating bank profitability quickly reversed the move, and by February the Nikkei fell to 14,865 yen. The pattern of 'surprise easing, fading expectations, disappointed selling' became clear. In June, the Brexit shock compounded the situation. Experience the risks of a market whipsawed by central bank policy.

In March 2018, President Trump imposed additional tariffs on Chinese goods, escalating the U.S.-China trade war. Retaliatory tariff exchanges drove global risk-off sentiment. The Nikkei fell about 21% from 24,124 yen in January to 18,948 yen in December. The sharp October decline (over 3,000 yen in two weeks) was also called the 'VIX shock.' A market that swung on every development in U.S.-China negotiations, testing your ability to handle headline (news) risk.
