[News] TSMC’s Kumamoto Fab Influence Expands, Economic Spillover Effect Expected to Exceed JPY 10 Trillion

TSMC’s fab in Kikuyo, Kumamoto Prefecture, Japan (Kumamoto Fab 1) is expected to begin mass production by the end of 2024, with plans for a second fab in the region. Thus, the influence of TSMC’s presence continues to expand, as per the latest estimates from local financial institutions.

Over the next decade, from now until 2031, the economic spillover effect of TSMC’s operations in Kumamoto is projected to surpass 10 trillion yen, marking a 60% increase from a previous estimate in August 2023.

According to a report from Nikkei citing Kyushu Financial Group (Kyushu FG), a new impact estimate has been released on September 5, showing that TSMC’s operations in Kumamoto Prefecture are projected to generate an economic spillover effect of approximately JPY 11.2 trillion over the next 10 years, until 2031.

This marks a 60% increase from the previous estimate of JPY 6.9 trillion published in August 2023. The projected impact on Kumamoto Prefecture’s GDP over the same period has also risen from JPY 3.4 trillion to JPY 5.6 trillion.

Reportedly, the previous estimate from Kyushu FG last August only considered the benefits of TSMC’s Kumamoto Fab 1. The latest report, however, includes the planned construction of the Kumamoto Fab 2 in its evaluation.

The upward revision is attributed to the expanded magnetic pull of TSMC’s Kumamoto operations (both fabs). The number of companies expected to set up or invest in the region has increased to 171, roughly double the previous estimate.

Initially, the first Kumamoto fab attracted strong interest from suppliers like Sony and Mitsubishi Electric. Following TSMC’s announcement in February to build a second fab, further investments are expected, not only from within Kumamoto but also from other prefectures and overseas suppliers, particularly from Taiwan.

Additionally, the economic impact is expected to extend to wage levels in Kumamoto Prefecture, with an estimated increase of JPY 380,000 in per capita annual income.

Meanwhile, as stated in an report from Bloomberg on May 11th, Kumamoto’s newly appointed governor, Takashi Kimura, once claimed that he would spare no effort to persuade TSMC to establish a third fab in the region.

In addition, a recent report from Kyodo News citing the interview with Taiwanese Minister of Economic Affairs J.W. Kuo has also hinted that TSMC plans to build a third fab in Japan, but with a projected timeline after 2030.

If the third fab is realized, the economic spillover effect is anticipated to expand further.
