/*
 * Japanese Phone number formatting rule is a bit complicated.
 * Here are some valid examples:
 *
 * 022-229-1234 0223-23-1234 022-301-9876 015-482-7849 0154-91-3478
 * 01547-5-4534 090-1234-1234 080-0123-6789
 * 0800-000-9999 0570-000-000 0276-00-0000
 *
 * As you can see, there is no straight-forward rule here.
 * In order to handle this, a big array is prepared.
