Sticks and stones may break my bones, but names can be an inspiration and a diverging point. See here...
Tokyo had a team in the Zenkoku League at the outset, and they were trying their best to be respectable. Reusing the "Senators" nickname from a previous entity, they were granted entry to keep the ZL at 6 clubs. During their first year of operation, the team was nicknamed the Tokyo Blue Stockings by the media after an influential feminist magazine from earlier in the century. It wasn't meant as a compliment,
so the team changed it to something more emotive but the team liked the idea so they ran with it.
After a time, the Tokyo Blue Sox (changed from Stockings) would come under new management, who gave the team a more imposing name that still sounded similar and eventually moved them out of the crowded Tokyo area to an unclaimed market - Sapporo.

In katakana,
buruu sokkusu and
buruuzaasu are sound-alikes, thus the change in that direction.
The logo is by Brandon Lamarche from what looks like a WHA team in Philadelphia. You know Japan would love a kangaroo mascot! And yes, I had to hand-outline the roo to remove the bell background from the original.
Font is
Kernit, outline on the logo and filled on the jerseys.

And although JPBO and [LEAGUE REDACTED] teams don't usually have non-letters as small logos, I liked the boxing glove enough to separate it out.

Just two jerseys in this one - our other pinstriped team, and a sharp blue/red combo away.
Other two teams will come one-a-day this week!
