What is the most expensive brand in Japan?

I'm curious to know, which brand in Japan holds the title of being the most expensive? Is it a luxury automaker known for its precision engineering and exquisite craftsmanship, or perhaps a high-end fashion house renowned for its intricate designs and use of premium materials? Alternatively, could it be a tech giant specializing in cutting-edge electronics, offering products that command a premium price due to their advanced features and exclusivity? I'm eager to find out which brand stands out as the pinnacle of luxury and exclusivity in Japan.
