Jesus Christ is this so embarrassingly basic and full of MC ass-kissing, it's hitting all the cliché "superior Japanese culture/knowledge" tropes. Most template of template isekais.
Edit: Having read all the chapters, it surprisingly has several good moments that don't go the way you expect.
Nono,
It cant be generic.
1) He isnt trying to make soy sauce
2) there is no swimsuit scene
3) there isnt a harem
4) he isnt trying to make pasta-machine/well-pump/carriage-suspension.
But yes, he has had item box, appraisal, and all magics handed to him on a plate.
And already has a "love" flag set up with the very first guild receptionist he met.
Also whilst his character had struggle, when he landed in the body, every suddenly started smelling of roses...
