A japanese twitter account

It is not normal for me to introduce or recommend something personal like twitter account to fellow HT81S lover. As HT81S are getting old, so are the news and updates available online. Hence I am looking more to something more personal for more news about HT81S and bump into this person from Japan twitter account. He got some pretty good picture about HT81S in his account which resulted the recommendation here.
If you have time, do look into his account below for picture of HT81S:-
