Input method does not change the keyboard layout.
Do you mean switching input sources does not change the keyboard layout? If so, why switching from Japanese Kana Kanji to German using Supser+Space changes the layout for German? And, why is the reverse not true? I don't think it is intuitive and convenient if switching sources from A to B changes the layout while B to A does not. Or, don't I get your points?
Because the German engine is XKB layout. Once you switch the engine to German, you will use German layout between kkc and 'de'. That means it would be good the session layout to 'de'.
If you need to switch the layout, you need to add 'JP' keyboard layout besides kkc. Or probably you can set the keyboard layout in kcc with the kkc setup dialog, /usr/libexec/ibus-setup-kkc
Actually, I use Japanese and German sources, which are not compatible with each other. According to you, to switch from German to Japanese, you have to switch German -> JP (Japanese plain) -> Japanse Kana Kanji. Don't you think that is annoying? The reverse is just Japanese Kana Kanji -> Germany.
If you use the multiple XKB engines, I'd suggest to configure kkc to set the preferred layout 'jp' likes ibus-setup-kkc.
