Basically the same but the Type 99 for the 7.7 Japanese has many features which were incorporated to reduce production time and cost.
Some of the things done include a flat sided extractor rather than contoured, a stamped rather than forged TG and FP, a slotted left lug rather than the solid lug on the Type 38, much less hand fitting and polishing, and less extensive heat treatment.
The Type 38 is an extremely well made and finished military rifle.
The Type 99 is an adequate military rifle but pales in comparison to the Type 38.
