Dentetsu Toyama baggage delivery opening hour

Hi.

I will be doing the Tateyama Kurobe Alpine Route on 23th May from Toyama side.

I've learnt that there is no online booking for the train from Dentetsu Toyama to Tateyama.
I've made reservation for the Tateyama cable car at 7am. Hence, i plan to take the first train from Toyama (5.28am).

Will the baggage forward counter at Dentetsu Toyama station open before the first train? I'm worried I have no enough time to settle my luggage and queue for the train ticket. If i missed the first train, i'll not be able to take the 7am cable car.

This page (though in Japanese):

Tells me that from Dentetsu Toyama they take luggage forwarding �gfrom the first train (till 9:50),�h so it looks like they take care of it.

Or is there any way you can send it from your hotel in Toyama city?

I have emailed the hotel and waiting for their reply.

Thanks for the reply.
