Kokoro was a great hotel - really friendly staff, clean and comfortable with beautiful views of the Alps.
It’s a few hundred meters - mostly flat and easily walkable, even in ski boots / from both the main Gondola and the Nakiyama Chairlift (opposite directions).
The room we had was a twin/double - the space was big, but we still had a bit of trouble navigating four large suitcases (our fault for having so much luggage). We also put the beds together to form a massive bed.
Breakfast was good and hearty - Australian travelers take note though: don’t expect an Australian hotel style buffet breakfast. It’s more like a European continental buffet, but with sausages instead of cold meats; and amazing Japanese green tea/mango roll cake instead of pastries.
