For a long time in Japan, the physical cards were limited because of IC inventory shortage. There was a big push to get people to use their phones during this time.

Also, travelers beware: some of the special "Suica" sold at Haneda (and maybe Narita, too?) expires and is completely dead after 30 days, even if it has a balance. I found this out the hard way. Buy a proper Suica at Shinagawa or another non-airport station.
