SoftBank Group Surpasses Toyota as Japan’s Highest-Valued Company by Market Capitalization

SoftBank Group overtook Toyota Motor as Japan’s most valuable company on Monday. Shares of the technology group climbed 14 percent in Tokyo trading, lifting its market capitalization above Toyota’s for the first time since 2000. The rally pushed SoftBank’s market value above ¥48 trillion, while Toyota’s stood near ¥46 trillion.

Toyota shares have fallen more than 10 percent this year, contrasting with SoftBank’s gain of more than 90 percent. AI-related stocks lifted technology shares across the region and contributed to the advance in SoftBank shares. The last time SoftBank briefly held the top position occurred during the peak of Japan’s internet bubble.

"Shares of SoftBank group climbed as much as 10% in Tokyo trading Monday, as AI-related shares climbed across the region," Reuters reported on June 1, 2026. The company is led by Masayoshi Son. The feat was last achieved only briefly during the peak of Japan’s internet bubble in 2000, based on market value including treasury shares.

The rally has propelled SoftBank shares up more than 90% this year, pushing the company’s market value above ¥48 trillion, higher than Toyota’s around ¥46 trillion.
