I attended Comic Market 106 (夏コミケー) on August 16-17, 2025.

I arrived at the early entry queue at 7:30 and stayed until 14:00. There is a pre-queue for early entry ticket exchange. This year, there was also a “cool relief” area in east hall 8, which was appreciated.

I used the same bag I used in c105_report. However, I did bring:

• 3x 900mL pocari sweat
• Daiso “cooling neck ring”
  • This seemingly was ineffective. According to the literature, I guess it will only be effective at low temperatures throughout a day, not necessarily during a prolonged event. I found that it melted slowly, and was fully melted by the time I left.
• A lot of snacks that I didn't eat (almost all were destroyed by heat)
• Lots of “energy” gel, which realistically was a mix of types focusing on replacing nutrients that would've been obtained by eating but weren't.

The temperature was about 32C at the peak during the waiting line. Compared to previous summer events, it felt like this was a lot less intense. The main thing I would say is that the shade might make it seem more tolerable but it really doesn't change much. I still drank about the same amount of liquids as I would expect to in warmer weather. I think that basically at this heat you can't really sweat more than the max. At the event specifically, I ended up drinking 3200mL of sports drinks (3x pocari sweat, plus the event specific sports drink).

For some reason, I developed a very bad headache during the waiting line, but I took ibuprofen and it was overall fine. I know it wasn't heat stroke because I didn't have any of the other signs. I suspect caffeine withdrawal, since I had been avoiding it going into the event and carefully ensuring I was hydrating properly.

I added a clipboard with a small amount of capacity, but I didn't feel it did anything substantial to help. I ended up sharing my circle.ms login with a friend so he could add his items directly to my list, and also asked him to provide a PDF with his desired items. I printed the venue map too, since east halls 1, 2, and 3 were closed. I found that having this accessible on paper was significantly better than relying on saved images on a phone.

I basically left earlier than usual only because I didn't get a lot of sleep the night before, and wanted to rest a little before preparing for the second day.
