Regarding the "iTunes Connect: App Store Changes for China and Japan" mail iTunes Connect just send us,
Effective October 1, 2015, new tax laws go into effect in Japan with respect to foreign business that provide electronic commerce to Japanese residents. You may now be required to administer Japanese Consumption Tax (current rate of 8%) imposed under these new tax laws. Further details on the tax law changes can be found at Ministry of Finance Japan website.
Anyone reach out a tax advisor regarding the obligation (or not) to administer Japanese Consumption Tax? The way I understand it, is that you are only required to adminster it if your sale in Japan are over 10M JPY.
