ATM Machine vs Staffed Counter — Head-to-Head Comparison

We compared these rates against a staffed walk-in counter (Kabukicho Money Exchange, Shinjuku) photographed two days earlier on June 26, 2026.

Bottom line: The self-service machine charges 5–10% more spread than a staffed counter. On ¥50,000 exchanged, that's a ¥2,500–5,000 difference.

💡 When to use a machine vs counter:

• Machine (Smart Exchange): You need ¥5,000–10,000 quickly, no time to walk to a counter, or it's your first time using yen and you want a simple, multilingual interface.
• Staffed counter: You're exchanging ¥30,000 or more and rate matters — walk 8 minutes to Kabukicho or use Wise + Seven Bank ATM.
