When you type romaji on a Japanese keyboard do some letters change to numbers?

Yes, when typing romaji on a Japanese keyboard, certain letters can change to numbers due to the input method settings. For example, typing "1" may produce "い" (i) if the keyboard is set to automatically convert input based on context. This behavior is intended to assist with kanji conversion, but it can lead to unexpected results if the user is not familiar with the keyboard layout. Adjusting the input settings can help prevent this issue.
