Nintendo released a Winter 2020 magazine in Japanese, a 100 pages of features and various ads for Nintendo Switch titles.
They did the same for a Summer 2020 magazine, and many pages feature Nintendo characters in stylish Winter fashion from their respective games – and the last page even includes the following Winter calendar of Peach/Toad!

A western release of this will probably never ever happen, which is a shame if you ask us.
