I admit, it's hard to separate fact from fiction with these write-ups. I draw too close to the real teams, and it feels like a lesser effort. This divergence point is a matter of degrees...
Our next Nihon League team started in Shimonoseki, then moved to Osaka after that until a permanent home in Kawasaki was built. The team drew poorly there, blamed almost entirely on the quality of the stadium, and relocated to Yokohama in the late 1970s. The team was always named the Whalers
(and yes, they will borrow Hartford's look when I get there), but as the 1990s rolled on and Japan took flak for its ongoing whaling practices, team ownership decided a new name was in order.
The new name would reflect the futuristic Minato Mirai project being built on Yokohama's waterfront, and give an optimistic glance to the future.
Heck, the team tried to refer to Yokohama Bay because of that, but that often wound up with Bay getting added to the team's actual name.

I clearly had Buzz Lightyear and the LGMs on my subconscious when it came to this set. And y'all aren't even going to get the super-90s-space-program designs until we get to the historical stuff!
Font is American Captain, main logo borrows from
CatalystStuff on Freepik, and features six starbursts for the six districts of Kanagawa prefecture. The starburst itself is a repurposed Office 2010 clip art.

Three jerseys in this one, and the alternate_textured file made my ZIP go over 3MB in size...
- Home white
- Road purple, with a wordmark that's a scootch too big
- "Galaxy" alternate; clearly Yokohama found the screen printing equipment
