schedule of rocket launches from Tanegashima?

I’d like to find a list of scheduled or speculatively planned launches from Tanegashima so that I could plan a vacation there around one. However, I can’t any lists more than a month or two into the future…

What I’ve found so far:

* JAXA’s T-w-i-t-t-e-r account is supposed to have info about upcoming launches, but seems to have only ones in the near future
* JAXA’s Press Releases: this seems like a good source, but again, can only see planned launches a month or two into the future: https://www.jaxa.jp/press/2023/index_j.html
* tourist information from Minamitane: this has exactly necessary information, but again, only for the very near future: http://www.town.minamitane.kagoshima.jp/sightseeing/uchiage.html

Does anyone know where to find a list of tentatively planned launches for, say, the next year?
