All three previous answers are excellent -- you need to get to Ueno station and, depending on the type of transit pass you have/purchase, use either the Yamanote Line Local for Shinjuku / Ikebukuro (Clockwise) or the Ginza Line Local to Asakusa. As others suggested, using GoogleMaps is best. We found our way around Tokyo without problems (and often GoogleMaps solved a transportation challenge when trains were delayed, etc.)

hi ,im not sure about it maybe some palaces wheelchair accessible.its better ask to your hotel

Technically it is, however when I visited it was so crowded I could barely walk. So just beware.

Yep, they're open. Tax discounts are for Items to be brought out of the country. They are sealed in bags with the receipts placed in your passport. For credit cards, they allow use for purchases over 5K yen

good morning travellers "ameyoko" market , short name for ameya-yokocho, is an exiting place where you can get lost easily among a huge variety of food and cloth selling . As other places in tokyo at the end of the year they will close before 8 p.m. but the very best moment to visit it is in the morning till 2 p.m.

Didn’t see a single one

No halah restaurant but there are food stalls

Isakeyas (drinks and snack style restaurants) are usually open late, past midnight. No, not too crowded late into the night except where the bars are. Local bars and nightclubs abound a block south of the Ueno Park, close to Hotel Park Side.
