Can I register the contract holder's name in hiragana when it's asking for kanji (Chinese characters) for "Omatome Seikyu Service (combined billing method)" or "Web Billing" on the online application screen?
You can input kanji (Chinese characters), hiragana, katakana, numbers, alphabets, and symbols in the field of "kanji," and katakana, numbers, alphabets, and symbols in the field of "katakana."
