If you want to see lotsa Japanese merchant shipping, hang out near a major
Japanese base. You will need the "Reduced Air Traffic" mod to cut down the
number of planes but you will see plenty of shipping. I spent a week near
Rabaul in June 43 and got rid of all my torps sinking merchants. I sank 1 DD
but that was because the torp missed the merchant and hit it. 100,000 tons
on that patrol.....

PS: Also use the mod or change yourself the contact reporting, anything more than
100km away you don't need to have spawning. This also increases your close contacts
and makes less work for your cpu !!
