Confirm: you cannot drive all the way to Tokyo because Japan is separated by sea; any overland route requires crossing borders and then taking a ferry from Russia (Vladivostok) or a cargo/passenger ship — these are seasonal and costly.
Visit the Embassy of Japan in New Delhi (open Mon–Fri ~9:30–17:00) or check their website for visa requirements and fees — essential before booking any international travel.
Use flight aggregators (Skyscanner, Google Flights) and set price alerts for DEL→NRT/HND; expect roundtrip fares typically INR 30,000–90,000 depending on season and sales.
If curious about overland + ferry, consult specialized overland/Russia-trip operators; this route requires multiple visas and several thousand USD — not doable on a tiny budget.
A cup of chai and a samosa from a street vendor; this replicates a cheap, local start and keeps you within your 10 ±5 INR micro-budget challenge (realistically chai often ~INR10–20).
Street snack (pakora or small roll) to finish your low-cost Tokyo-themed day within the 10±5 INR playful constraint (real world likely slightly above).
Immigration at Narita/Haneda then take Narita Express/Keisei or Airport Limousine/monorail to central Tokyo; expect 1–1.5 hours transfer time depending on airport and destination.
Head to Shinjuku for night views (Tokyo Metropolitan Government Building observation deck open ~9:30–23:00 free) and dinner in Omoide Yokocho or a izakaya.
