Is it OK to climb Mt. Fuji the week before the official climbing season opens?

Congratulations for a great online resource on Mt Fuji and Japanese culture.

I've read a lot of your supplied information but I was hoping to ask your opinion of our plans, if I could trouble you for a moment.

A Norwegian friend and I would like to climb Mt Fuji however our window is the week just before the season opens, 25 June - 1 July 2019.

Some things that I've read indicate that pre-season climbing is difficult to organise and ill-advised... however I note that some of the guest houses seem to be open in late June.

Could I ask if you have any thoughts as to whether its possible and which trails to use / guesthouse we might book into? We like the idea of trekking up late afternoon, resting in the guesthouse, then aiming for the sunrise summit and descent the next day... but would open to what ever you recommend. We are 50 yrs old but experienced snow campers / trekkers in Australia and Norway.

Many thanks for any assistance, regards

Adam
