• Canon had 37.3% of Japanese camera market (fixed lens plus system cameras)
• Nikon had 26,7% of Japanese camera market
• Sony had 13,1% of Japanese camera market
• Olympus had 6% of Japanese camera market
• Ricoh had 5.8% of Japanese camera market

Compared to year ago (April 2018)

• Canon sold -1,3% less cameras (in number of units)
• Nikon sold -15% less cameras
• Sony sold -6,6% less cameras
• Olympus sold -13,8% less cameras
• Fuji sold +19,4% more cameras

Now if we look at value:

• Nikon got -28,5% less for sold cameras
• Sony got +14,5% more for sold cameras
• Olympus got -21,3% less for sold cameras
• Fuji got +0,6% more for sold cameras
