Tokyo in late winter is special. Clear skies, crisp air, fewer tourists, and neon reflections on cold pavement set the backdrop for late-night ramen runs and incredible sushi. It is also the smartest window to catch lower airfares to one of the world's best food destinations.
A full trip for two typically runs about $5,000. You do not need to hand over all that cash at once if you spread the cost over time using a predictable monthly payoff plan.
Remember that 0% interest is a strict payoff deadline, not free money. If you still have a balance when the 18 months end, regular interest rates will kick in on the remaining amount.
