Rakuten Acquires Giants’ Catcher Takuya Kai in Cash Trade — Mid-Contract Switch Breaks the Mold

From our other sites

The story

On the 30th, Rakuten announced it has acquired catcher Takuya Kai (33) from the Giants in a cash trade. Kai had only just joined the Giants as a free agent from SoftBank in the 2024 offseason, signing a reported five-year, ¥1.5 billion deal — which makes a mid-contract trade like this a rare occurrence. This season he started behind the plate in just 3 of his 13 appearances, trailing behind Ohshima and Kishida on the depth chart. On 5ch, posters debated everything from which team is actually covering the rest of his contract to what exactly Rakuten stands to gain from the move.

It was decided on the 30th that Rakuten will acquire Giants catcher Takuya Kai (33) in a cash trade.
Kai exercised his domestic free-agent rights in the 2024 offseason while with SoftBank and moved to the Giants on a reported five-year, ¥1.5 billion contract. In his first season there, 2025, he missed time after fracturing his right middle finger in August, but still made his presence felt on both sides of the ball, batting .260 with 4 home runs and 20 RBIs in 68 games. This season, though, he's started behind the plate in just 3 of his 13 appearances, with playing time going mainly to Ohshima and team captain Kishida instead.
This is the second year of his five-year deal, which had run through 2029 with the Giants — making this a mid-contract trade with very few precedents.

Dead serious, LMAO

They already picked up Watanabe too — they're really stockpiling catchers huh
32AnonymousOct 30, 2026 12:11

Re: #16
They cut 3 guys outright, and Ohta might be leaving too
19AnonymousOct 30, 2026 12:10
This is basically the front office admitting the signing was a bust.
Can't believe they actually went through with it
36AnonymousOct 30, 2026 12:11

Re: #19
The Giants are a player-first organization
so if a guy's not getting playing time, they'll trade him out for his own good
42AnonymousOct 30, 2026 12:12

Re: #19
It's basically an 'unagi' switcheroo (slang for a bait-and-switch deal)
51AnonymousOct 30, 2026 12:13
Well they're starting rookie Watanabe right out of the gate, so of course there's no playing time for Kai
56AnonymousOct 30, 2026 12:14

Re: #51
Way too early to make Watanabe the sole starter
52AnonymousOct 30, 2026 12:13
Is Kai gonna be next year's 'banished hero' isekai protagonist? (a web-novel trope where the exiled MC thrives elsewhere)
75AnonymousOct 30, 2026 12:17

Re: #52
Even if Rakuten makes the Japan Series next year, is Kai even gonna see the field?
63AnonymousOct 30, 2026 12:15
If they're planning to use him as a backup catcher, that's way too pricey — Rakuten's lost it
77AnonymousOct 30, 2026 12:17

Re: #63
Ohta's leaving via free agency and they already cut Ishihara, so without a move like this they couldn't even field a farm-team game

Thought this was a joke but it's actually real

In a case like this, does the salary carry over too? Or do they redo the contract from scratch?
88AnonymousOct 30, 2026 12:19

Re: #71
The contract carries over exactly as it is
That original five-year deal transfers with him
72AnonymousOct 30, 2026 12:16
Just like with Sumitani, they toss catchers they don't need anymore straight in the trash lol
122AnonymousOct 30, 2026 12:23

Re: #72
The only real issue is the salary clearly doesn't match the role — they don't want him as the main guy,
but as a rotating/platoon catcher he's totally fine
76AnonymousOct 30, 2026 12:17
If the Giants are covering the salary that's one thing,
but if Rakuten's footing the bill, isn't that just dumb?
86AnonymousOct 30, 2026 12:18

Re: #76
Hint: it's a cash trade
89AnonymousOct 30, 2026 12:19

Re: #86
Wait, isn't the Giants the side paying the cash here?
111AnonymousOct 30, 2026 12:22

Re: #86
Even if Rakuten only pays the Giants some small trade fee, they're still inheriting Kai's remaining 3 years at ¥300 million a year — that's a massive loss lol
78AnonymousOct 30, 2026 12:17
This is basically a tragedy caused by long-term, big-money contracts
Could NPB just ban multi-year deals or something?
85AnonymousOct 30, 2026 12:18

Re: #78
What would be the point of banning them?
103AnonymousOct 30, 2026 12:20

Re: #78
It's not a tragedy at all
The player gets paid big and is happy, and the club wanted him enough to pay that much
80AnonymousOct 30, 2026 12:17
Rakuten taking on the rest of his contract salary — aren't they loaded?
Also, if the Giants treat a guy who chose them as a free agent like this, nobody's gonna want to sign there anymore
87AnonymousOct 30, 2026 12:18

Re: #80
Vissel Kobe was throwing cash at washed-up veterans too — they genuinely just have money to burn
83AnonymousOct 30, 2026 12:18
So who's gonna pick up Ohta then?
96AnonymousOct 30, 2026 12:20

Re: #83
It's a bidding war between Hiroshima, Hanshin, and Chunichi
110AnonymousOct 30, 2026 12:22

Re: #83
Apparently he himself wants to go to Hiroshima
94AnonymousOct 30, 2026 12:20
Catcher Tobashira's gonna see this news and just need to lie down lol
105AnonymousOct 30, 2026 12:21

Re: #94
Honestly it only makes sense he went FA because the Giants came calling
102AnonymousOct 30, 2026 12:20
What's actually in this for Rakuten?
108AnonymousOct 30, 2026 12:21

Re: #102
They get to stay cozy with the Yomiuri Group
124AnonymousOct 30, 2026 12:23

Re: #102
It's them clearing out Kakizawa
104AnonymousOct 30, 2026 12:20
Even if he's just there to mentor Watanabe, that's one seriously expensive coach
113AnonymousOct 30, 2026 12:22

Re: #104
Guess that just shows how much they're counting on him
Getting his SoftBank-era data/insight is huge
109AnonymousOct 30, 2026 12:21
Even heading into his free-agent year, both Ohshima and Kishida were already reasonably solid options — it was really just [manager] Abe who wanted Kai specifically
Guess this is what happens once Abe's not around anymore
119AnonymousOct 30, 2026 12:22

Re: #109
Well, back then Ohshima had been moved to a different position anyway
125AnonymousOct 30, 2026 12:23
Is the salary split 50/50 with the Giants on this?
There's no way it benefits Rakuten to inherit all ¥300 million
130AnonymousOct 30, 2026 12:24

Re: #125
Developing Watanabe, plus the SoftBank data

Background and Key Debates

Multi-year contracts signed after exercising free-agent rights aren’t unusual in NPB, but it’s extremely rare for a player to get traded to another team in the middle of one of those deals. Kai had only just moved from SoftBank to the Giants as a free agent in the 2024 offseason, and this trade carries that entire contract over to Rakuten intact. What split opinion in the thread was how the remaining salary would be divided between the Giants and Rakuten — since this is officially a ‘cash trade,’ Rakuten presumably has to put up some money of its own, but the exact split hadn’t been disclosed at the time of reporting, so even the comments never got past speculation. As for Rakuten’s motive, posters floated several theories — mentoring rookie catcher Watanabe, tapping into his SoftBank-era data, strengthening ties with the Yomiuri Group — but it’s worth noting none of these are official explanations from the club, just fan speculation. Kai’s playing time had dropped off sharply after his free-agent move largely because of how deep the Giants’ catching corps is, and how this trade plays out for his career will depend entirely on how Rakuten chooses to use him going forward.
