tips for collecting 'Fukei-in' postmarks
If you'd like to collect 風景印 'Fukei-in', scenery postmarks in Japan.
1. PREPARE a mount with a stamp of a value greater than the postcard's postage cost 63JPY(0.57USD) as of today, or an official postcard (官製はがき Kansei-hagaki) you can buy at every post office.
2. VISIT a post office which has a 'Fukei-in' postmark. Not always have it, you should search before you visit. Post offices in tourist areas often have it.
3. GET your 'Fukei-in' at the post office! You should say '風景印を押してください (Fukei-in wo oshite kudadai)' means 'Please stamp it with a Fukei-in.'
