alpine route ticket late november

hello, i want to go to murodo from ogizawa side on 12th nov 2024, but in web ticket website it can only purchased until 4th nov, when i can buy web ticket for 12th nov online? or it can't bought online? thankyou

I believe a main reason why advance purchases are not offered after November 4 is that the route frequently gets interrupted by snow, and it would be a hassle to offer refunds for these tickets. Also, it is considerably less busy along the route, so there is less of a need for advance reservations at the entrance points.
