It might be a shock to you, but Japanese sources say otherwise.
Sometimes the claims were close, sometimes exaggerated.
Same thing goes with the Jpanese claims of allied aircraft.
For example, look at the SBD claims, 138 kills? Those are totals that look more like a fighter group. Look at the PB4Y claims. 210? Thats quite some tally for an airplane that hardly saw any action in the the big air battles in the SW pacific, and CBI.
