Közi tweeted about this: ã¤ã‚‰ã„ã€ã€çªç„¶ã™ãŽã¾ã™ã‚ˆã€è³¢ã•ã‚“ã€
Badly translated it reads something like "Painful,, and too sudden, Ken"
Sugiya's tweet was longer: ã¾ã ä¿¡ã˜ã‚‰ã‚Œãªã„ã§ã™ã€‚ ZIZ&森岡賢コラボã‹ã‚‰ãƒ©ã‚¤ãƒ–や飲ã¿ã§ã”一緒ã™ã‚‹æ©Ÿä¼šãŒå¢—ãˆã€ã„ã‚ã„ã‚ãŠè©±ã§ããŸã‚Šæ¥½ã—ã‹ã£ãŸæ€ã„出ã—ã‹ãªã„ã§ã™ã€‚本当ã«æ®‹å¿µã§ãªã‚Šã¾ã›ã‚“。 è³¢ã•ã‚“ã®ã”冥ç¦ã‚’ãŠç¥ˆã‚Šã—ã¾ã™ã€‚
Which using online translators to get the jist of this, he wrote about it being unbelievable, ZIZ and more joining Ken Morioka live and drinks. Something about collaborating and fun memories. He ends it with rest in peace or praying for Ken's soul.
I'm sure someone who reads Japanese can come up with a better translation.
It is touching to see different artists pay their respect to Ken Morioka.
