The calendar for collab café and merch pre-order deadlines is on its way. Stay tuned!
We will list pre-order, post-event mail-order and lottery deadlines based only on official announcements, with calendar subscription (ICS) support.
Akiba glossary
- Denki-gai (Electric Town)電気街
- Akihabara's cluster of electronics, computer and parts shops, which grew out of post-war street stalls selling radio parts. Many used smartphone and PC parts shops are still here.
- Jigo tsūhan (post-event mail order)事後通販
- Online orders for merch that was originally venue-only, opened after an event or collab café ends. The order window is often short, and many shops ship only within Japan.
Right after a new iPhone launches, the previous models tend to get cheaper toward the end of the year. I'll keep watching every day.
