Potential semiconductor hubs in Japan: Kyushu, Tohoku, and Hokkaido

Date: 06/11/2023
Market researcher TrendForce has come out with its latest study on how Japan is attempting to establish advanced semiconductor manufacturing during this geopolitical upheavals.

TrendForce Has identified three potential semiconductor hubs that might emerge in Japan, located in Kyushu, Tohoku, and Hokkaido.


Below are the more details shared by TrendForce on the potential of each of these places:

I. Kyushu

Kyushu has swiftly ascended as a semiconductor hotspot, thanks in part to the advent of JASM (TSMCís Kumamoto Plant). Even prior to TSMCís entry, Sony and SUMCO, a behemoth in raw wafer production, have been operating in the region for several years. Additionally, numerous small and medium-sized semiconductor-related enterprises have established themselves in the region, rightfully earning Kyushu the title of "Silicon Island."

With JASM slated for completion, it is set to house one of the most advanced semiconductor factories in the region, embracing manufacturing processes ranging from 12 to 28nm. Even a future migration to more advanced processes is on the table depending on customer demand.

Given its strategic location adjacent to Sonyís existing CIS factory, and considering Sonyís stake in JASM, expect a synergy that strengthens their collaboration in semiconductor manufacturing and packaging and testing technologies.

II. Tohoku

If Japan is considered a global hub for the production of semiconductor raw materials, then the Tohoku region serves as the heart of this crucial industry. This region, enveloping areas around Sendai and Fukushima, is home to the Renesas Yonezawa plant, and major raw wafer producers SUMCO and Shin-Etsu. Bolstered by Tohoku Universityís reputation in semiconductor materials research and a rich talent pool, Tohoku stands out.

On October 31st, PSMC officially unveiled plans to build a 12-inch wafer plant in Sendai, initially focusing on the 40nm process node, with advanced processes in the roadmap. Automotive electronics will be a production priority, further amplifying Tohokuís semiconductor significance.

III. Hokkaido

Rapidus, a Japanese enterprise aiming high with 2nm semiconductor technology, has surprisingly chosen Hokkaido as its base, catapulting the region into Japanís third semiconductor stronghold. Government plans indicate that Rapidus could be a magnet for upstream equipment and material suppliers to flock to Hokkaido, potentially sparking a semiconductor community boom. Its proximity to Chitose Airport also promises seamless talent and resource flow. With the factory under construction and set to complete in 2024, and mass production earmarked for 2027, Rapidus is on track, with much of its R&D conducted in collaboration with IBM in the United States, showcasing Japanís ambition to spearhead advanced semiconductor manufacturing.

Japanís resurgence in the semiconductor arena is palpable, with the Ministry of Economy, Trade, and Industry fostering multi-faceted collaborations with the private sector. With a favorable exchange rate policy aiding factory construction and investments, the future looks bright for exports. However, the looming shortage of semiconductor talent in Japan is a concern. In response, there are generous subsidy programs for talent development. Japan is strategically positioning itself to reclaim its former glory in the world of semiconductors.

"Taiwanese firms collectively command a hefty 65% market share in global foundry revenue, with TSMC alone claiming a whopping 56%. This underscores Taiwanís crucial position globally and has motivated regions worldwide to establish semiconductor industries within their territories while considering a multitude of factors." stated in the release by TrendForce.
