Is the Japanese Stock Bull Run Still Worth Chasing? 5 High-Potential Japan ETFs to Follow Buffett’s Lead

·

Japan’s stock market has finally emerged from the shadows of its so-called "lost three decades." With strong corporate reforms, accommodative monetary policy, and surging foreign investment—fueled in part by legendary investor Warren Buffett—the Nikkei 225 has reached record highs, capturing global attention. For Taiwanese investors, gaining exposure to Japan’s revitalized economy through Japan ETFs offers a simple, efficient alternative to picking individual stocks.

This guide explores the top Japan ETFs available to investors in Taiwan, covering broad-market index-tracking funds, high-dividend options, and sector-specific plays in areas like semiconductors and trading companies. We’ll also examine the macroeconomic shifts driving Japan’s resurgence and help you assess whether now is the right time to invest—while highlighting key risks to consider.


Understanding Japan’s Two Key Market Indices: Nikkei 225 vs. TOPIX

Before diving into ETFs, it’s essential to understand the two primary benchmarks that most Japanese equity funds track:

Nikkei 225 Index

Compiled by the Nihon Keizai Shimbun (The Nikkei), this index includes 225 of the largest and most liquid companies listed on the Tokyo Stock Exchange. It uses price-weighted methodology, meaning higher-priced stocks have a greater influence on performance. As Japan’s most recognized index, it’s often seen as a barometer of the nation’s economic health.

TOPIX (Tokyo Stock Price Index)

Maintained by the Tokyo Stock Exchange, TOPIX covers all companies in the TSE Prime Market and uses market-cap weighting. This makes it a broader and more diversified representation of Japan’s overall equity market. Institutional investors often favor TOPIX for its comprehensive market exposure.

Types of Japan ETFs Available in Taiwan

Investors in Taiwan can access a range of Japan-focused ETFs through local brokers. These funds vary by tracking index, investment strategy, and risk profile. Below is a breakdown of the main categories.

1. Broad Market (Market-Cap Weighted) ETFs

These funds aim to replicate the performance of major Japanese indices, offering diversified exposure to the overall economy—ideal for investors bullish on Japan’s long-term outlook.

2. High-Dividend Japan ETFs

As Japanese firms prioritize shareholder returns, dividend-focused ETFs have gained traction—perfect for income-seeking investors.

3. Sector-Specific Japan ETFs

For investors with thematic views, these ETFs focus on high-growth or strategically important industries.

Semiconductors

Japan plays a critical role in the global semiconductor supply chain, especially in materials and equipment.

Trading Companies (Sogo Shosha)

These diversified conglomerates handle everything from energy to infrastructure and have surged in popularity thanks to Buffett’s investments.

4. Leveraged & Inverse ETFs

Designed for short-term traders, these products amplify daily moves but carry significant risk due to compounding effects.

Not suitable for buy-and-hold strategies.


Why Invest in Japanese Stocks Now?

Several structural changes suggest Japan’s equity market may be entering a new era of sustainable growth.

Corporate Governance Reform & the PBR Revolution

The Tokyo Stock Exchange has pushed companies with Price-to-Book Ratios (PBR) below 1 to improve capital efficiency. This has led to increased share buybacks, higher dividends, and better ROE—making Japanese equities more attractive to global investors.

End of Deflation & Wage Growth

After decades of stagnation, Japan is seeing inflation stabilize around 2%. Coupled with rising wages—driven by labor shortages—this could fuel stronger domestic consumption and break the deflationary cycle.

Monetary Policy Normalization

The Bank of Japan (BOJ) ended negative interest rates in 2024, marking a pivotal shift. While rates remain low, normalization supports financial sector profitability and boosts investor confidence.

Global Supply Chain Rebalancing

Geopolitical tensions have driven companies like TSMC to build fabs in Japan, revitalizing local tech ecosystems and creating spillover opportunities across sectors.

Buffett Effect

Warren Buffett’s continued增持 (increased holdings) in Japan’s五大商社 (Big Five Trading Houses) has drawn global attention to undervalued Japanese assets. His endorsement signals long-term confidence in Japan’s economic transformation.

Frequently Asked Questions (FAQ)

Q1: Do I need to worry about currency risk when investing in Japan ETFs?
A1: Yes. Since these ETFs hold yen-denominated assets, fluctuations between the JPY and TWD can impact returns. A weakening yen reduces your TWD gains even if the ETF rises in value. Some funds offer hedged versions, but they come with higher fees.

Q2: How do Taiwan-listed Japan ETFs differ from U.S.-listed ones like EWJ?
A2: Key differences include trading currency (TWD vs USD), settlement time, tax treatment (U.S. ETFs withhold 30% dividend tax), and trading hours. For most Taiwanese investors, local ETFs offer greater convenience and simpler tax reporting.

Q3: Why are Japanese trading companies suddenly so popular?
A3: These firms act as global intermediaries across energy, metals, and infrastructure. They’ve improved governance, raised dividends, and benefit from rising commodity demand—all while trading at historically low valuations.

Q4: Which type of Japan ETF is best for beginners?
A4: Broad-market ETFs like 00645 (TOPIX) or 00661 (Nikkei 225) are ideal starting points due to their diversification and lower volatility compared to sector or leveraged funds.

Q5: Are dividends from Japan ETFs taxable in Taiwan?
A5: Yes. Dividends are included in your annual comprehensive income tax declaration. There is no separate withholding tax for Taiwan-listed ETFs.
