Today, Microsoft still struggles to sell consoles in Japan. Of the 46.9 million Xbox Ones sold worldwide through the second quarter of 2019, just 0.3% of them have been in Japan, according to the International Data Corporation.
According to Famitsu. XBOX ONE sold 108,000 in Japan (as of September 2019.)
108,000 ÷ 0,003 = 36,000,000
