@@transcoder9even before that Ladakh was a part of tibet and zhangzhung and not separate from it. Kingdom of Ladakh only became after the 900 AD fall of Tibetan empire.
Thank you for visiting Ladakh, please take rest for 24 hrs atleast before you go out, Japanese people live at sea level so it would be difficult but drinking warm water and eating chocolate will help a lot. If possible take high altitude sickness pill 12 hr ealier before visiting by plane. I’m glad you met the japanese lady, she would’ve given you good instructions. Ladakhi people are usually very kind but people from lower India are coming to work here and spoiling the atmosphere. Anyway, very nice editing kudos to you sir.
