How to change language to English

It depends on the component. For example, if it is the dash cluster, you need a high-end scanner like my Xtool, which is full-function and can reset the language; even changing it from km to miles is the same for many cars. Others, like the R35 GT-R, require an Autel scanner or dealer tool to do it, unless you have an Xtool or other all-system scanner that has been coded to bypass the security systems on the GT-R ECU. Desoldering the EEPROM is generally less of a pain for DIYers. Radios are generally similar in cars with this problem where a OBD2 tool is needed, but some radios allow for change without it except for some JDM imports from Honda and Toyota.

I mention the R35 because of how locked down it is in terms of ECU and dash cluster access - at one point, it took the tuners a good minute to break it for tuning. Once they got in Nissan tried in subsequent MYs after the 2009 was cracked but even they gave up and went to checking for tune flags.

My scanner (Xtool iP616) can scan the whole car, but cannot do ADAS or reset the Honda clusters at all. You will likely be looking at an Autel scanner to change it.
