The hotel website does a great job in displaying the rooms. One of the picture is an AR walk-through type that you can go in and explore. The Grand Prix Circuit View King - where we are at now - has a lot of space. The living room has a large very comfortable couch. There is a smaller size couch in the bedroom with a lazy chair as well. Balconies have a small-ish day bed and patio chair/table set. The suite also has its own powder room in addition to a separate closet area.

Breakfast is kind of standard Japanese 4/5 star offering, the usual western offerings, mixed w Japanese items. Pastries are ok, fresh squeeze juice, and a few items off the egg menu. We asked for a French toast - which is not on the menu - and the chef happily obliged. Breakfast is done at the Trofeo restaurant. My Japanese hotel experience is not too extensive - I guess Conrad Tokyo breakfast would be the closest comparison to Fuji Speedway.

The other vibe that sticks out for us - and we like it a lot! - is the lack of crowd density so to speak. The hotel feels big in space, but really low on people count, so it never felt like you're just a group in the crowd. I read the first post - and kind of surprise - that there are only 120 rooms. The front desk staff told us that they are quite busy - but it just never felt like it. It felt like a place for special retreat with excellent motorsports tie ins.

To answer one of the above question abt track experience:
Sadly no. The hotel can help coordinate - but the available date among other was 4/18 - and that was our arrival date - so we did not get to participate. We did watch a few Super GT practicing (among others) - an AMG GT that has mean backfires/burbles every time it shifts, and a pair of NSX which looked really tidy when navigating some of the curves.
