Applying to public policy grad school with a background in pharmaceutical sciences

[almighty]

Ladies and Gentlemen of the forum, 

I am new to this,  so please excuse my mistakes if any.

I am an undergrad in pharma sciences but what i want for my masters is something related to public policy and governance,  that topic catches my attention anyday.

The pandemic has left me pondering more over how well health graduates with the proper background and training could tackle world wrecking  health problems.

I have tried exploring quite a few options but most of the public policy schools seem to ask for experience.

One school am particularly interested is the GraSPP at Todai, and also utokyo's global health program.

Since my undergrad stream happens to be a bit different,  i woul like to know from experienced seniors on how i should approach and how fair are my chances.

Thanks in advance
