If I'm not mistaken it is just the opposite.The Japanese built a large number of Arisakas modified to meet the needs of the Italians,and chambered for the 6.5 Carcano.Can't find my reference just now,but if memory serves me correctly there were about 35,000 of them in that contract.
If I'm correct,I believe they will feed from a mauser type magazine,as opposed to the manlicher clip system of the carcano.
