Possible - around 4km. But why would you want to walk instead of taking the subway/jr trains?

Visa waiver to US unlikely IMO. The moment US waive visa to Malaysian, that very month cases of jump aeroplane increase by 9000% liao

If can't find Kobe in Tokyo then just go for the other "Big Three" Matsusaka / Ohmi lo.

No worry, this rule is more relaxed for female tag Some more female tag + staff tag
Anyway u buy tix liao? If not yet, why not fly open jaw KL - Tokyo then Osaka - KL. then only need to shinkansen one way.

Depends how many days in total you have for Tokyo/Kanto area. For example if you only had 3 days in Tokyo then it might make more sense not to take any day trips.

Quoting this because I didn't know LYN supports auto tables

Read properly man. That website gives a list of countries for which "visa is granted automatically on your arrival into Japan." Any country not on the list, you can still get temporary visitor status but you need to apply visa from home country before travelling.

Malaysia not on the list presumably because if your passport not ICAO compliant you still need to apply visa.
