We chose this transport formethod of transport in order to discover some places far from mass tourism.

FirstThe first few hours on the road wasere pretty impressive, fortunately, he is a good driver!

SOn the same day, we were oin a big supermarket and we discovered a large choices of japanese foods!

“On a supermarket” would mean you were standing on top of the roof

We needed to translate all productthe , but the translation was not very effective.

For exeample, on the back of asome packaging, the traducnslation with Google Lens was "Big wave, him, old man, old woman, fairy tail, moon."

Just for sushi, the gap with the fFrench price was astonishing!
