Ryujo was also flush-deck, and much smaller than the Carrier in the pic (the french "bearn"
).
In fact the Ryujo was intended to be under the 10.000 ton line so it could be built out of the washington treaty tonnage limitation
According to that treaty a carrier was a ship displacing more than 10k tons, so the japanese took advantage of this loophole by building a ship which nominally displacced less than that ammount, so its tonnage won't count for the total.
In the end the ship was a disaster, and had to go through a thorough rebuild which increased its displacement over the 10k mark.
WEll summing it up, no, it's not ryujo
