Solar observation satellite "Hinode" was launched in 2006.   This year marks the 15th year of launch. It has encouraged the use of Hinode data for not only  research but also education.  "Let's Look at the Sun with Hinode" is a joint observation campaign with  high and junior high school students. Called “With Hinode!” for short, it is highly evaluated as a unique activity. In Japan, the students have high acitiviy of solar observation in the extracurriicular class. This  joint observation  started in 2010 and we have been carried out  for 11 years. The students compare Hinode data with their observation data  and deeply study the sun.  Additionally, they held presentations at their schools’ festivals, prefectural science contests, and junior sessions in the astronomical society’s annual meeting. This year, "With Hinode" is carried out from Aug.2  to Aug.7. In July,17 we gave a previous online tutirial  to the partipant students for this joint observations. In this talk, we reflect  " With  Hinode" to date and report this year's observation results.

The sun is the most popular star for us. Therefore, the public have high interests in the solar activity as ever. In fact, in the previous 24th solar maximum(2009-2020), when the solar eclipse, the big sunspots, and the huge solar flare occurred, the public including mass media pay intense attention to such solar phenomena. In addition, the public have high interests in the relation between the solar activity and climate change on the earth. Since solar observation satellite "Hinode" was launched in 2006 and even now, the observation data has been used on the astronomy communication scene in various ways. After that, STEREO and SDO were also launched and similar activity have been done on the astronomy communication scene. In Japan, with these solar observation data, we have been promoting public use of Hinode data working group and joint observations with high/junior high schools. Teaching materials with Hinode data have been developed and used in the class room practice. These activities have drawn the attention of solar researchers at home and abroad. From now on, the next 25th solar cycle is coming, the solar activity will be active again. New solar observation spacecraft, Parker Solar Probe (PSP) and Solar Orbiter were already launched towards the inner heliosphere. PSP has already new findings about the interesting structures of solar wind as initial results. DKIST is also operated as the solar ground-based solar observatory. In Japan, Solar_C_EUVST is planned as a successor of Hinode. It is expected that we can obtain new high spatial resolution data and new information of the heliosphere  from these current and future observation instruments next by next. In particular, the solar phenomena as solar flares, CMEs, solar wind have influences on the near-earth space. If the solar research make progress with the new instruments in future, we can deeply understand space weather relating our life. Moreover, that might lead to new knowledge between solar activity and climate change. Thus we would obtain the opportunities to communicate the new solar astronomy with the pubic. In this virtual conference, we would like to opportunities for not only reflecting our and others’ astronomical communication to date but also generating new method and idea based on the new coming solar data in the future. In addition, we would also communicate the relation between the solar activity and climate change among the participants.

The sun is very popular objects for us and the public are very interested in the solar activity. For example, when big sunspots appear and a huge flare occurs, the public including mass media pay intense attentions to such solar phenomena. As the back ground of science/astronomy education/outreach in Japan, some specific points are as below. 1. The sun is surely studied in science class of formal education. 2. Extracurricular activities of natural science in high and junior high schools. 3. There are many science museums, planetariums, and  public observatories. 4. Amateur astronomers have high activities. Since Hinode launched in 2006, the observation data have been used in various ways on the scene of astronomical education and outreach. In this talk, I  focus two specific activities with use of Hinode observation data. One is Hinode Data Use Working Group, which contributes in outreach at the early phase of Hinode observations.  The other is “Let’s Look at the Sun with Hinode together”, which is simultaneous observation campaign  with high  and junior high  school students. This is highly evaluated as a unique activity and continue for ten years. The students compare Hinode data with their own observation data and deeply  understand the sun.   In addition, I introduce  outreach activities in Institute for Fusion Science where I am working now.
