Tell me which currency you mean by '50-60 Thousand' — INR (Indian rupees), USD (US dollars), JPY (Japanese yen), or another currency. This changes what’s realistic for flights, accommodation, meals and transport.
Do you prefer budget (hostels/guesthouses), mid-range (3-star hotels), or comfort (4-star)? Also, which city will you arrive into (Tokyo or Osaka) or do you need flight suggestions?
