Japan Market Close: Semiconductor Stocks Plunge, Nikkei Average Reverses Sharply 日本市場引け: 半導体関連株急落と日経平均大幅反落
On the 28th, the Japanese stock market saw a sharp decline in the Nikkei Average as semiconductor-related stocks faced a flood of sell-offs. Concerns over the previous day's decline in US semiconductor stocks and the entry of Chinese companies into the semiconductor manufacturing equipment market soured investor sentiment.
Nikkei Average Trends
The Nikkei Average closed on the 28th at 62,364.92, down 2,566.27 yen from the previous trading day, marking a significant drop that brought it below the 63,000 yen level for the first time in approximately two months. The TOPIX (Tokyo Stock Price Index) also followed suit, closing down 102.48 points at 3963.59.
In addition to concerns about over-investment in AI, reports of Chinese companies commencing production of immersion deep ultraviolet (DUV) lithography equipment intensified selling pressure on semiconductor-related stocks, significantly dragging down the indices.
Trading by Investor Type
While the specific breakdown of trading by investor type for the 28th has not yet been released, data from the third week of July (July 13-17) shows that foreign investors turned to a net selling position of 286.3024 billion yen in the cash equity market. Conversely, retail investors were net buyers of 407.4795 billion yen, and trust banks were net buyers of 58.80041 billion yen. This week saw a significant decline in the Nikkei Average, with foreign investors actively selling while retail investors engaged in buying the dip.
Individual Stocks and Sectors in Focus
Semiconductor-related stocks, in particular, experienced significant declines today. Sell-offs concentrated in index-heavy stocks such as Advantest and Tokyo Electron, contributing heavily to the widening of the Nikkei's decline. Background factors include a roughly 5% drop in US Nvidia shares the previous day and reports that a Chinese state-owned enterprise has begun manufacturing DUV lithography equipment, strengthening caution about intensifying competition in the semiconductor market.
Japan Exchange Group's stock price also saw a temporary decline of 3.2% at one point. Despite the announcement of an increased profit forecast for the fiscal year ending March 2027, the positive news had a limited impact, overshadowed by the overall deterioration of market sentiment.
Factors Driving the Market and Future Outlook
Today's sharp decline in the Japanese market was primarily driven by a combination of receding exuberance in global AI-related stocks and concerns over intensified competition due to China's accelerated efforts towards semiconductor technological self-reliance. Negative sentiment related to semiconductors spread across the Asian market, with South Korea's KOSPI index triggering a circuit breaker after an over 8% drop.
Future market focus will likely center on earnings reports from domestic and international companies, US economic indicators, and the results of the US Federal Open Market Committee (FOMC) meeting, which begins tonight. These announcements are expected to provide crucial clues that will influence the current volatile market sentiment.
Today's development, where a broad sell-off in semiconductor-related stocks dragged down the entire market, once again highlighted the significant impact of global technology sector trends and geopolitical competition on the Japanese market. Investors are advised to maintain a cautious stance, paying close attention to upcoming key economic events and corporate earnings announcements.
Sources: atpress.ne.jp, diamond.jp, prtimes.jp, yahoo.co.jp本日28日の日本株式市場は、半導体関連株への売りが殺到し、日経平均株価が大幅に反落しました。前日の米国市場での半導体株安や、中国企業の半導体製造装置市場参入への懸念が広がり、投資家心理が悪化しました。
日経平均株価の動向
本日28日の日経平均株価は、前営業日比2,566円27銭安の62,364円92銭で取引を終え、約2ヶ月ぶりに63,000円を割り込む大幅な下落となりました。TOPIX（東証株価指数）も同102.48ポイント安の3963.59ポイントと、連れ安となりました。AIへの過剰投資懸念に加え、中国の液浸型深紫外線（DUV）露光装置製造開始報道が半導体関連銘柄に売り圧力を強め、指数を大きく押し下げました。
投資主体別売買動向
本日28日の投資主体別売買動向はまだ公表されていませんが、直近でデータが確認できる7月第3週（7月13日～17日）の現物市場では、海外投資家が2,863億240万円の売り越しに転じました。一方、個人投資家は4,074億7950万円の買い越し、信託銀行は588億41万円の買い越しとなりました。この週は日経平均株価が大きく下落した週であり、海外勢の売りが目立つ中で個人投資家が押し目買いに動いた形です。
注目された個別銘柄とセクター
本日は特に半導体関連株が大幅に下落しました。アドバンテストや東京エレクトロンといった指数寄与度の大きい銘柄に売りが集中し、日経平均の下げ幅拡大に大きく寄与しました。背景には、前日の米エヌビディア株が約5%下落したことや、中国政府系企業がDUV露光装置の製造を開始したとの報道があり、半導体市場における競争激化への警戒感が強まりました。
また、日本取引所グループの株価も一時3.2%安となる場面が見られました。2027年3月期の増益見通しが発表されたものの、市場全体のセンチメント悪化に押され、ポジティブな材料への反応は限定的でした。
市場を動かした要因と今後の展望
今日の日本市場の急落は、主に世界のAI関連株に対する過熱感の後退と、中国の半導体技術自立加速化による競争激化懸念が重なったことによるものです。韓国KOSPI指数が8%超の下落でサーキットブレーカーが発動されるなど、アジア市場全体で半導体関連の悪材料が波及しました。
今後の市場の焦点は、国内外の企業決算や米国の経済指標、そして今晩から開催される米連邦公開市場委員会（FOMC）の結果に集まるでしょう。これらの発表が、現在の不安定な市場心理を左右する重要な手掛かりとなると考えられます。
半導体関連株への一斉売りが市場全体を押し下げた今日の展開は、グローバルなテクノロジーセクターの動向と地政学的な競争が、日本市場に与える影響の大きさを改めて示しました。投資家は、次の重要な経済イベントや企業業績発表に注目し、慎重な姿勢を保つことが求められます。

Yeah, it's no wonder the sell-off is concentrated in semiconductor-related stocks. China's moves are concerning.そりゃあ、半導体関連に売りが集中するのも無理ないか。中国の動きは気になるね。
The rise of Chinese semiconductor manufacturers is indeed a cause for concern. It's a bitドキドキ (excitingly nervous) to see how the competition will unfold from now on.中国の半導体メーカーの台頭は、確かに懸念材料だよな。これからの競争がどうなるか、ちょっとドキドキするね。
Yikes, Japan's Nikkei took a beating today. Saw the news about those chip stocks getting hammered. Guess the US market dip yesterday and China's semiconductor push really spooked everyone over there. Hope my own portfolio isn't feeling this chill.Yikes, Japan's Nikkei took a beating today. Saw the news about those chip stocks getting hammered.
