This looks straightforwardly wholesome and pleasant - exactly what a normal, good aspiring culture would want in a deity.

One thing, however: the benevolent trader aspect might need a little more authority.
I think it would be good to add in that the Priests of Sakura are charged with watching over the commerce of their flock, to make sure none are harmed by unscrupulous practices.
I don't want to get into economic politics, but as we've seen in the recent recession, unchecked capitalism can lead to hardship for those at the bottom of the heap.
A good god of trade ought to make sure that doesn't happen. Part of the responsibility of the priesthood could then be a kind of auditing, checking the guilds for social responsibility and all that.
