Hello Bhudda, welcome to Jref!! Great to know we got someone from Kobe in here, because I will be moving to Kobe myself in 45 days! Hope you will have fun on the forum, and make some friend up here, and that you are able to find what you are looking for.
I am sorry I don´t know anything about what to do in Toyama, and the surrounding areas in the golden week. But maybe others in here know it!
