Is it cheaper to use a JR Pass?

Only if you are traveling to multiple cities like Kyoto and Osaka. If you are staying solely within Tokyo, a local subway pass is much cheaper.

Do I need to tip in Tokyo?

No. Tipping is not practiced in Japan and can even be considered rude.

Exploring Tokyo on a Budget

You can experience Tokyo for $80–$100 per day by utilizing local train passes, eating at convenience stores or tachinomiya (standing bars), and prioritizing the city's vast array of free observation decks and parks. Avoid taxis entirely and skip the pricey guided tours in favor of walking tours or independent exploration.

Get a Tokyo Subway 72-hour Ticket. Purchase the 1,500 yen ($10 USD) 72-hour pass at the airport or major tourist offices. This covers all Tokyo Metro and Toei Subway lines, saving you significant money compared to single-ride fares.
Use Convenience Stores for Breakfast and Lunch. Stop at 7-Eleven, Lawson, or FamilyMart. A high-quality onigiri, egg salad sandwich, or bento box will cost between $3 and $6, which is a fraction of the cost of a sit-down cafe.
Visit Free Observation Decks. Skip the paid Tokyo Skytree or Tokyo Tower. Head to the Tokyo Metropolitan Government Building in Shinjuku, which offers panoramic city views from the 45th floor for free.
Master the 'Standing' Dining Scene. Look for 'tachinomiya' (standing bars) or ticket-machine ramen shops. You can get a hearty bowl of ramen or a set of yakitori skewers for $7–$12.
