Around 40 Otoko no Isekai Tsuuhan

Kenichi Hamada, a man nearing forty, wakes in a dangerous forest in another world with no explanation for how he got there. He has no heroic spell or legendary weapon, but he does discover an ability far better suited to his practical nature: he can still access a Japanese online store and order modern food, tools, and equipment.

Kenichi quickly learns that selling a few Earth-made goods can earn him a comfortable living in a nearby town. He has little interest in building a commercial empire, though; what he really wants is a secluded cabin and a quiet, self-sufficient life. Unfortunately, unusual merchandise attracts unusual attention, and every person he helps seems to bring another reason his supposedly peaceful new life refuses to stay peaceful.
