Format guide
Yokohama address format
A Yokohama address follows the Japan order: 〒 postcode, prefecture, city/ward, chome-banchi. Samples on this page keep the city field fixed to 横浜 so the rest of the form can be checked against a stable value, and phone fields use the +81 country code.
Postal codes
Postal codes for Yokohama follow the Japan pattern: 3 digits + hyphen + 4 digits (〒). A representative value looks like 160-0022. Because the city stays 横浜, you can use these samples to verify that your form rejects a postal code paired with the wrong city.
Typical use cases
Yokohama samples are fictional and are meant for layout checks, validation rules, and format learning. Do not use them for checkout, identity verification, shipping labels, or to work around regional restrictions.
How to use test data
In development you can use these samples to check field length, line breaks, international characters, and responsive layouts. For payment, identity, logistics, or compliance flows, use official sandbox data from your provider—do not submit these samples to live systems.
