Their first single: Subarashii Ongaku O Subarashii Uta, was released September 29, giving them only six days to promote.

March 18, It was announced that Boss Huang Ning would be graduating August 11,2010:

Tsunku's Comment:

Ever since releasing her first book, it seemed like Huang would be writing more and more often. She even wrote Pure Form!!. Huang is very wise when it comes to writing, but it seemed was becoming a priority over being an idol. Huang skipped two practices to work on her writing! so I sat her down one day,with assisant manager Akami and we talked. Huang told us that she wanted to graduate from Happy Jikan. Akami decided a graduation date for her: August 11,2010.

Huang's Comment:

I love Hello!Project and all my fans. But, I am deciding to leave Happy Jikan. Ever since I released my book, I felt like I was actually tempted to leave Happy Jikan, and since I am leader now, I tried to be responsible and forget it. But things started to get worse. The itch started to come back and bother me even more, to the point where I felt that it was taking over my responsibilities as the leader, so when I sat down with Tsunku and Akami, I just confirmed it with them, and eventually talked to the company about my choice. Even though I have chosen to leave, I will never stop supporting the members and I will always remember to check up on them. I have learned so much from them, the seventh generation have even started to represent the group better than I ever did when I was younger! I'm putting the group into their and Yin Lu's hands. So, August 11, 2010 I will be graduating to attend college and later on, become an author and maybe a director, since I've also taken a big interest in movies and script writing'. Until the end, let's continue to have fun together!

  • Every two years, they have a 'Birthday' concert for the formation of the group in 2000. 
  • Shiawasena Christmas was Happy Jikan's first single to not be sold in China. The reasoning for this is because the group had a limited amount of time to prepare for the single, thus focusing on promoting in Japan only.

  • Happy Jikan was the first Hello!Project group to be fully made up of Chinese/Taiwanese members.
  • Happy Jikan is currently the only group to have a boss and a co-boss. (Other groups are known for just using the term "Leader/Sub-leader").
  • All Happy Jikan auditions have five rounds.This is because instead of having the fourth round being the final round like most Hello!Project auditions,the fourth rounds is used to teach the auditionees more advanced Japanese.
  • Da Meihui is the shortest girl to join Happy Jikan,being only 139 cm when she joined the group. By the time Da graduated,she was only 142 cm.
  • Happy Jikan's former dance instructor, Inochi Amaya, quit in 2006 afte rumors spreading of her being racist and saying abusive things towards the members in class. Since then ,Usa & Usagi have been their official dance instructors.
