Shirakami Sanchi is a vast region of forested mountains in northern Japan, straddling the border of Aomori and Akita prefectures. It is home to one of the largest virgin beech forests in the world, which has had barely any human impact over the centuries. That is why the core area of Shirakami Sanchi has been registered as a UNESCO World Heritage site since 1993. On this edition of Journeys in Japan, Catalin Munteanu visits this ancient forest, which is also a popular destination for trekking and river activities, such as rafting.

Yamanashi Prefecture has been a pioneer in winemaking in Japan since the mid-19th century when farmers began converting rice and mulberry fields into vineyards for the native Koshu grape. Nowadays, the crisp white wine has been winning awards at global wine events. On Journeys in Japan, we meet the passionate people behind the most talked about Koshu labels -- some coming from old winery families and others from unrelated industries.
