Spending HKD in Japan: what you need to know
Local currency
Japanese Yen (JPY) ¥
Cash necessity
High — Cash is king in Japan. Carry ¥10,000–20,000 at all times. Budget ¥5,000–8,000/day for food and transport.
Card acceptance
Cards accepted at major hotel chains, department stores, and some chain restaurants. Cash remains mandatory at most local restaurants, izakayas, temples, ryokans, and transportation.
ATM situation
Not all Japanese ATMs accept foreign cards. The two reliable networks are 7-Eleven (Seven Bank) ATMs — open 24/7, widely available, charge ¥110–220 fee — and Japan Post ATMs (in post offices, 9–5 Mon–Fri). Most bank ATMs (Mizuho, MUFG) do not accept foreign cards.
🇭🇰 Tip for Hong Kong travellers in Japan
Use a zero-forex card like Wise or Revolut to eliminate your home bank's currency markup on HKD conversions. This alone saves 2.5–3% per transaction.

Japan money tips for Hong Kong travellers
7-Eleven ATMs (Seven Bank) are the most reliable for foreign cards — available in every 7-Eleven convenience store 24/7.
Japan Post ATMs also work but close at night and on weekends.
Load your Wise card with JPY before you go — avoids the mid-trip conversion guessing.
IC cards (Suica, Pasmo) for trains can now be topped up with foreign Visa/Mastercard at some stations.
¥10,000 and ¥1,000 notes are most useful. Larger bills can be hard to break at small shops.
